What we do for clients

Discovery, design, engineering, deployment and the maintenance afterwards — one team, accountable for the whole thing. We do not hand a project between departments and we do not disappear at go-live.

AI Integration & Automation
Most AI features fail not because the model was wrong but because nobody could tell when it was. We build retrieval grounded in your own data, with sources attached to the answer and a person in the approval path wherever the output carries consequences — assistants, document and workflow automation, and search that understands intent rather than keywords. The model sits behind an interface as a dependency rather than an architecture, so cost, latency and quality stay measurable and changing provider is a configuration change.
AI Assistants & ChatbotsLLMs & GenAIRAG & Smart SearchWorkflow AutomationEvaluation & guardrails
Custom Software Development
Systems built around how your business actually runs, rather than how a package expects it to. Internal tools, operations platforms, multi-module systems — the work usually starts by mapping a process somebody is currently running in spreadsheets.
Web Application Development
Applications, not brochures: dashboards, portals, admin systems and SaaS products where people work all day. Built to stay fast as the data grows, and structured so the second year of changes costs about what the first did.
Mobile App Development
Android applications, native or cross-platform depending on how much of the device the product actually needs. Built against real networks and real battery budgets, and released through a pipeline rather than from a laptop.
E-Commerce Solutions
Storefronts and marketplaces where payments, stock and fulfilment reconcile. Most e-commerce work we are called into is not the storefront — it is the order and inventory data sitting behind it.
API Development & Integration
REST and GraphQL services with authentication, rate limiting and versioning designed in rather than added later. Integrations that fail loudly and retry safely, because a silent integration failure is one your customer discovers first.
Cloud, DevOps & Hosting
AWS and Cloudflare infrastructure released by pipeline, with monitoring and alerting configured before launch instead of after the first incident. Accounts in your name, so the infrastructure is yours from day one.
UI / UX Design
Interfaces designed against the real workflow, with a component system so the tenth screen costs less to build than the first. Accessible by default — keyboard, contrast and screen readers — not retrofitted before launch.
Maintenance & Support
Someone who knows the system is still there in month eighteen. Dependency and security updates, performance work as the data grows, and the small changes that otherwise queue up for a year.
MVP & Product Strategy
Mostly deciding what not to build. We scope the smallest version that can genuinely be tested with users, ship it, and leave the architecture open exactly where the answer is not yet known.
Industries

Domains we have shipped into

Twelve so far. Domain expertise is not something a studio has on day one — it is what you are left with after sitting with the people who do the work. Here is the constraint each of these turned out to be about.

E-Commerce & Retail

Inventory that is right in two places at once, and a checkout that survives the one day a year traffic triples.

Healthcare & Wellness

Records with consent and retention rules attached, and audit trails that assume somebody will ask who read what.

Education & E-Learning

Progress that survives a dropped connection, and assessment nobody can quietly reorder after the fact.

Fintech & Payments

Money as exact integers, idempotent transactions, and reconciliation designed before the first payment is taken.

Logistics & Supply Chain

State that changes in the field, offline, and must merge without inventing a shipment that never existed.

Real Estate & Property

Listings with a lifecycle, documents with versions, and enquiries that route to a person the same day.

Travel & Hospitality

Availability that cannot be double-sold, and prices that recompute correctly when a rule changes mid-season.

Astrology & Spiritual Tech

Real astronomical computation rather than templated content — the difference our own StarTime is built on.

Marketing & SaaS

Multi-tenant from the first table, usage metering that bills honestly, and onboarding that is not a support ticket.

Media & Entertainment

Large files, rights windows, and a delivery path that stays fast when a piece unexpectedly finds an audience.

Manufacturing & ERP

Processes that already exist on paper, mapped exactly before they are automated, not redesigned around the software.

Non-Profit & Government

Reporting formats that are not negotiable, accessibility as a requirement rather than a preference, and long support horizons.

How we engage

Four ways to work with us

Every engagement starts with a written scope and a fixed number, so you approve the cost before anything is built. Which shape fits depends on how well defined the work already is.

01 · Discovery
Discovery sprint
For an idea that is not yet a specification. One to three weeks turning goals into something buildable.
  • Requirements and scope document
  • Architecture and stack decision
  • Wireframes for the core screens
  • Costed delivery plan
02 · Build
Fixed-scope build
For work that is defined. An agreed scope, an agreed price, delivered in demonstrable iterations.
  • Fixed price against a signed scope
  • Working software every iteration
  • QA, deployment and handover
  • Code and IP transferred to you
03 · Team
Dedicated team
For a roadmap rather than a project. Named engineers working to your priorities, billed monthly.
  • Named senior engineers
  • Your backlog, your ceremonies
  • Scale the team up or down
  • 30 days' notice, no lock-in
04 · Run
Support & maintenance
For software already live — ours or someone else's. Kept patched, monitored and moving forward.
  • Monitoring and incident response
  • Security patches and upgrades
  • An agreed monthly budget for changes
  • Takeover of an existing codebase
Selected Work

Case studies

We do not only build software for clients — we own and operate three platforms of our own. Each was the whole job: architecture, product decisions, interface, deployment, and the burden of keeping it running afterwards. That is the same team you would be hiring.

01 In production

ZivaOffice

HR, payroll and utilization for services firms that bill people to clients

6
Modules, one data model
0
Rounding errors, by construction
100%
Payroll runs reproducible
Challenge
Services firms run payroll in one system, timesheets in another and utilization in a spreadsheet. Bench cost stays invisible until month-end, and billed hours never reconcile with what was invoiced.
What we built
A multi-tenant platform joining employee master, leave and attendance, salary structures, payroll runs and statutory filings to clients, projects, timesheets, allocation and rate cards. Held to payroll-grade standards: money as exact integers rather than floating point, effective-dated records rather than overwrites, and an audit trail on every change.
Result
Bench cost is visible the same day instead of at month-end, and a payroll run from any prior period reproduces exactly — verified by an integration suite that runs against a real MySQL instance, not an in-memory substitute that quietly disagrees with production.
02 In production

ZivaPilot

All-in-one growth platform for small businesses

5
Tools replaced by one
4
Lead channels, one inbox
6
Modules on shared data
Challenge
A small business owner needs a website, a card to share, somewhere for enquiries to land, a social presence, and someone to say what to do next. They end up paying for five disconnected tools, none of which talk to each other.
What we built
One dashboard combining a website builder, digital business card, auto-captured contact book, a unified leads inbox spanning web forms, WhatsApp, social and Google, scheduled social posting, and an AI growth advisor that reads the business’s own metrics and returns a prioritised list of actions.
Result
Four lead channels land in a single pipeline, so an enquiry gets answered rather than discovered later in an inbox nobody was watching. Each of those channels is a third-party API that fails in its own way, so the engineering is retry semantics, idempotency and partial-failure handling — a silent integration failure is a lost customer.
03 In production

StarTime

Vedic astrology, re-engineered as a life-intelligence platform

3
Languages, one core
3
Chart systems computed
0
Sun-sign templates
Challenge
Astrology apps serve generic sun-sign content. An authentic reading requires sidereal astronomy computed from an exact time and place of birth — precision consumer apps rarely attempt, because it is real computation rather than a lookup.
What we built
A computation engine built on the Swiss Ephemeris with the Lahiri (Tirukanitha) ayanamsha, producing Rasi, Navamsa and Dasamsa charts, Vimshottari dasa periods, transits, Sade Sati, compatibility, muhurtha and remedies — delivered through daily-to-yearly guidance, an AI assistant that answers in plain language, and typeset PDF reports.
Result
Every chart is computed from the user’s own birth time and place rather than served from a template, in English, Hindi and Tamil off a single computation core. A calculation wrong in the fourth decimal produces a chart that reads perfectly and is entirely wrong, so accuracy here is not a quality target but the product itself.

Client engagements are covered by confidentiality agreements, so they are not published here. We are glad to walk you through relevant work and put you in touch with references on a call.

How we deliver

Five stages, and you see the work at every one

No black boxes and no surprise reveal at the end. Each stage has a defined output you receive and sign off before the next one starts.

01

Discover

1–3 weeks

Goals, users, constraints and the systems already in place. We come out with a scope somebody can build against and a number you can approve.

DeliverableScope, architecture & costed plan
02

Design

1–3 weeks

Screens, flows and the data model. The interface is designed before it is written, so the arguments happen in Figma rather than in code review.

DeliverableWireframes & design system
03

Build

4–16 weeks

Shipped in iterations with a working demo at the end of each. Tested, reviewed and deployed continuously — never a single reveal at the end.

DeliverableWorking software, every iteration
04

Launch

1–2 weeks

QA, performance, security review, monitoring and a controlled go-live. Handover includes the accounts, the repository and the documentation.

DeliverableLive system, IP transferred
05

Operate

Ongoing

Monitoring, incident response, security patching and the next set of features. The team that built it is the team that keeps it running.

DeliverableRetainer or fixed monthly budget
Engineering

The standards we hold our own systems to

Money as exact integers. Records versioned rather than overwritten. Completed payroll runs frozen so any of them reproduces years later. Nobody preparing and approving the same payment. Tests against real databases, never a substitute.

About

A studio that ships and then stays

Most studios describe how they work. The more useful question is what they have already had to get right, and what happened when it mattered.

ZIVARA is a software engineering studio in Villupuram, Tamil Nadu, working with clients worldwide. We build systems that have to keep running long after the launch, and we are usually the ones still running them.

Client engineering is one half of the business. The other is our own — ZivaOffice for HR, payroll and utilization, ZivaPilot for small-business growth, and StarTime for Vedic astrology across three languages. Operating them ourselves means we carry the consequences of our own architecture decisions, which is the shortest way we know of learning to make better ones.

It also means the standards we ask of a client’s system are the ones we already hold our own to. Nothing on this site describes a practice we have not had to live with at two in the morning.

Why a studio that runs its own products is a different proposition

An agency hands over a system and finds out it was wrong from a support ticket, if at all. We find out because it is our phone that rings. Running ZivaOffice, ZivaPilot and StarTime in production means we carry our own architecture decisions for years, and pay for the cheap ones ourselves.

That changes what we recommend. We are cautious about dependencies because we have had to upgrade them. We insist on effective-dated records and audit trails because we have had to answer “what did this say in March” about our own data. We test against real databases because we have been burned by an in-memory one that quietly disagreed with production. None of it is unusual engineering — it is ordinary engineering held to a standard, learned in the only way that sticks.

The three case studies above are the evidence. They are our own systems, so we can show you the inside of them in a way client work under NDA does not allow.

Our Studio

Built from Villupuram, Tamil Nadu

We work from a first-floor studio and are building out the second. Clients are worldwide and most engagements run remote, but the engineering itself is done here — by people on our own payroll, in one room, not routed to subcontractors you never meet.

Talent and technology decide software; addresses do not. The cloud we deploy to, the languages we write in and the standards we review against are not geographically scarce. What a smaller city gives us is continuity — engineers who stay with a product long enough to remember why it was built the way it was, which is the part a client actually feels.

Careers

Join ZIVARA

We hire engineers who want ownership of what they build rather than tickets to close. You will work on production systems with real users, alongside people who review your code properly.

Software Engineers
React, Java and Spring Boot, Node.js, Python. You will own features end to end — schema to screen — on systems people depend on to get paid and get work done.
AI & ML Engineers
LLMs, retrieval and automation inside products we run ourselves, which means you watch how your work behaves in production rather than in a notebook.
UI / UX Designers
Design systems and interfaces for software people use all day — payroll screens, admin tools, dense tables. The unglamorous surfaces, where clarity actually decides whether the work gets done.
Interns & Freshers
You will read a great deal of code before you write much of it, and your first pull requests will be reviewed properly. We take interns on to keep them, not to staff a quarter.

Don’t see your exact role? Reach out anyway — the fastest way to apply is right below in Get in Touch.

FAQ

Questions, answered

The questions buyers actually ask before a first call.

We build custom web and mobile applications, e-commerce platforms, APIs and cloud-hosted products — from early-stage MVPs for startups to complex, multi-module systems for established businesses. We are a poor fit for pure staff augmentation, or for work where nobody on your side is able to make a decision.
One conversation about what you are trying to build, then a written scope. Which of our four engagement models fits depends on how well defined the work already is — a discovery sprint if the idea is still forming, a fixed-scope build if the specification is settled. Nothing is billed before you have the scope and the number in writing.
Any studio that quotes before understanding your scope is guessing. Cost tracks the size of the team and how long it is engaged, so a focused MVP and a multi-module platform sit an order of magnitude apart. We scope first and put a number in writing; what you are buying is priced before it is built, never discovered afterwards.
A focused MVP is usually a few weeks; a multi-module platform runs to several months. We work in defined stages with a demo at the end of each, so progress is something you see rather than something you are told about, and the timeline is re-checked against reality at every stage rather than promised once at the start.
React and Vite on the front end; Java with Spring Boot, Node.js and Python on the back end; Android for mobile; AWS and Cloudflare for cloud and hosting; and LLMs such as Claude and OpenAI for AI features. We pick the stack per project rather than forcing one on every client — our full default stack and the engineering standards behind it are published on our engineering page.
Yes, and it is a large part of what we build: AI assistants and chatbots, LLM-powered search over your own data, document and workflow automation, and predictive insights. We integrate Claude, OpenAI and custom models. The harder part is usually not the model but grounding it in your data and making its output something users can check — that is the work we do.
Yes. Maintenance, monitoring, security patching and continued feature work are a standing engagement model, not an afterthought. The team that built the system is the team that keeps it running, which is why our own three platforms are still in production.
You do. On client engagements the source code, the repository and the IP belong to you on delivery, and infrastructure accounts are created in your name and handed over. We sign an NDA before you share anything sensitive, and we never reuse your code in someone else's product.
Most of our work is remote and always has been. Indian Standard Time gives us a full working-day overlap with the UK and Europe, and we shift hours to cover US mornings where a project needs it. You get a named point of contact rather than an account manager, a written update every week, and access to the same tracker we use ourselves.
