Frontend development in Chennai
Long-lived SaaS products built in Chennai often carry several generations of front end at once: a legacy framework in the settings pages, React in the newer modules, and three different date pickers depending on which team built the screen. Customers notice the inconsistency, the product feels older than it is, and larger customers ask whether every screen works from a keyboard and a screen reader.
We consolidate these front ends without stopping feature work. A shared component library in React and TypeScript that new screens use from day one, older screens migrated in priority order behind the same routes, and accessibility built into the components so each migrated screen gets keyboard and screen-reader support for free. Visual regression tests catch the screen nobody touched breaking. The migration is measured and reported, so you know how much is left.
Chennai is where Indian SaaS learned to sell to the world. Zoho is headquartered here and has grown without venture capital. Freshworks was founded here in 2010 by two former Zoho employees, and Chargebee was started in a Chennai apartment a year later by a team with Zoho roots, with Freshworks as an early customer. That lineage produced a distinctive kind of company: product-led, careful with money, selling to small and mid-sized businesses on several continents from offices in Chennai. Chennai's SaaS teams tend to be strong on product and short on specific capacity, not on talent in general.
The city's second identity is industrial. Chennai is often called the Detroit of Asia, with vehicle plants including Hyundai's and BMW's on its outskirts, a large base of component and electronics manufacturers, and a major port. Those firms have the same problem as manufacturers everywhere in India: their operations have outgrown the spreadsheets and older systems that run them, and their information arrives late and in the wrong format. Around the port, freight forwarders, customs brokers and warehouse operators face the same problem with paperwork instead of parts, and the cost of a lost document is a container that sits on the quay.
Its third is healthcare. Chennai is often called the health capital of India, and hospital groups such as Apollo Hospitals and specialist centres such as Sankara Nethralaya draw patients from across the country and abroad. Healthcare software here has to earn trust. Health records are among the most sensitive data there is, and hospital systems increasingly need to exchange data with each other and with the national digital health stack rather than sit in isolation. Referrals, international patient coordination, patient apps and group-wide reporting all need building. Getting consent, access logging and integration right matters more than the interface.
We are in Bengaluru and share your time zone, so the working day is the same on both sides and a question asked in the morning is answered that morning. You talk directly to the engineer who writes the code. Most of the work happens in your repository, your issue tracker and a shared chat channel, which suits teams used to working in writing, and the runbooks and architecture notes are written as we go.
We are the right fit for a defined piece outside your team's usual specialism, a migration with an end date, or the gap while your next hire serves their notice. Start with a fixed-price two-week piece and judge us on what ships. Chennai agencies and product studios can also bring us in white-label, under their own name.
Four ways this arrives.
We measure on real devices and real traffic first, not a lab score on a fast laptop. The fix is usually less JavaScript: a smaller bundle, images sized for the screen, and third-party scripts that stop blocking the first render.
A procurement checklist, a customer complaint, or a letter from a lawyer. We fix the causes rather than the line items: real buttons, labelled forms, focus that lands somewhere sensible, and automated checks in CI so it stays fixed.
Global state that everything reads, no types, and three versions of the same modal. We add TypeScript file by file, put tests on the flows that make money, and move shared pieces into one component library as screens are touched.
Usually for search visibility or first-load speed. We move it route by route behind the same URLs, so the old app keeps serving while the new one takes over, and nobody has to sign off a risky weekend cut-over.
A Next.js web app with five operational dashboards and Tableau reports rendered in place, without a second login.

How do you work with teams in Chennai?+
We are in Bengaluru and share your time zone, so calls, reviews and releases fit inside your normal working day. We work in your tools, Slack, GitHub and Linear or whatever your team already uses, and most of the conversation happens in writing, where it lasts. You talk directly to the engineer writing the code, from the first 30-minute call onwards, and runbooks and architecture notes are written into your repository as we go.
Can you work inside a mature SaaS product without slowing our team down?+
Yes. We read your code and conventions before changing anything, follow your review and release process, and take a defined piece of work, such as a billing migration, a new integration, a performance problem or an infrastructure move, so the changes stay in one place rather than spreading across the product. We work in Node, Python and TypeScript, inside your repository, and leave runbooks and architecture notes for your team.
How does your rate compare to hiring in Chennai?+
PayScale puts a mid-career software engineer in Chennai at about ₹12 lakh a year. Our published rate is $35 an hour, with a $5,000 minimum. That buys a senior engineer who writes the code, works in your Slack, GitHub and Linear, and starts within days, with no recruiting round, notice period or employment overhead. Begin with a fixed-price two-week piece at $2,800 and judge us on what ships.
Can you build software for Chennai's hospitals?+
Yes. FM360, the platform we built for a healthcare estate, runs its facilities and maintenance in production. For hospitals and diagnostic chains we build referral and patient-coordination platforms, patient apps in Tamil and English, and warehouses that join every branch's systems into one set of numbers. Consent is recorded per purpose, every access to a record is logged, and integrations use standards such as FHIR where the other side supports them.
Do we need to move to Next.js?+
Not always. If the app sits behind a login and nobody finds it through search, a well-built React single-page app on Vite is simpler to host and easier to reason about. Next.js earns its keep when first load and search visibility matter, or when you want rendering close to the data. We will tell you which case you are before anyone rewrites a route.
Can you work from our Figma files?+
Yes, and we will ask questions about them. Designs rarely show the loading state, the empty state, the error, or what happens when a name is twice as long as the mock-up assumed. We raise those early and propose something, rather than inventing it quietly in code and leaving your designer to find out in review.
Will you build us a design system?+
We will build the one your product needs, which is usually smaller than people expect: design tokens, the components you actually use, and Storybook to show them. We extract it from the screens you already have rather than designing it in isolation, because a component library nobody migrates to is just a second way of doing things.
How do you handle accessibility?+
We build to WCAG 2.2 AA by default, test with a keyboard and a screen reader, and run automated checks in CI so regressions are caught before they ship. Automated tools find only part of the problem, so we also test the key journeys by hand: sign-up, checkout, and anything a user does every day.
Do you only do the front end, or the API as well?+
Either. A lot of front-end pain is really an API shaped for a different screen, and when that is the case we can fix both sides. If your backend team owns the API, we write down what the front end needs from it and agree the contract with them, rather than working around it in the browser.
