React Apps That Don't Become Spaghetti
We build React applications that are still maintainable two years and three developers later. Strict TypeScript, sensible state management, real testing, real performance budgets, and an honest opinion about when Next.js is the right call and when it isn't. No 400-component prop drills, no useEffect hell, no "we'll refactor it later".
You don't need another rewrite.
You need a frontend that scales with your team.
Most React codebases don't fail because React is bad. They fail because nobody set the rules in week one: no state strategy, no folder convention, no testing bar, no performance budget. Six months in you have 14 ways to fetch data, three competing form libraries, and a bundle that takes 8 seconds to load on a hotel WiFi. We build React the way it should have been built from day one.
A 6,000-line file nobody wants to touch
Components that fetch, transform, render, animate and route — all in one place. Every change breaks something else. The team has stopped opening pull requests on it.
The bundle is 4MB and the page takes 9 seconds
Moment.js, lodash, three icon libraries, the entire MUI catalogue, and a date picker that ships its own copy of React. Lighthouse score in the 30s. Mobile users bounce.
useEffect chains that nobody understands
State syncs back and forth between five hooks, fires three extra renders, and triggers a request loop on Tuesdays. The original developer left. The new one is afraid to change anything.
What You Actually Get
No vague deliverables. Here's exactly what lands in your hands.
A documented architecture
Folder structure, state strategy, data fetching pattern, form pattern, routing pattern — all written down in an ARCHITECTURE.md so the next developer is productive on day one, not week six.
Tests that actually run in CI
Vitest or Jest for units, React Testing Library for components, Playwright for end-to-end. Coverage thresholds enforced. PRs blocked when coverage drops.
A real performance budget
Bundle size budget per route, LCP/INP/CLS targets enforced in CI via Lighthouse, real-user monitoring (Sentry / Vercel / SpeedCurve) wired in from day one.
Source in your repo, deploys in your account
Your GitHub org, your Vercel/Netlify/Cloudflare account, your CI. No vendor lock to us. If we walked away tomorrow, your team ships on Monday.
A Real Frontend Engineering Team
Shipping React well is more than one developer with a Figma file. Six roles you get on every Pillai Infotech React build.
Senior React Engineer
TypeScript, hooks done right, Suspense, Server Components, concurrent rendering. Has read the React source code and can tell you why your component re-renders.
UI Engineer / Design Systems Lead
Tailwind, Radix, shadcn, Storybook, design tokens, accessible primitives. Builds the component library so the rest of the team stops reinventing buttons.
Frontend QA & Test Lead
Playwright, Testing Library, visual regression with Chromatic or Percy. Catches the bugs your unit tests miss because they only test what the developer remembered.
Performance Architect
Sets the bundle, LCP, INP and CLS budgets. Code-splits, tree-shakes, lazy-loads, prefetches. Cares when a route gains 40KB.
Accessibility Lead
WCAG 2.2 AA, keyboard nav, screen reader testing, focus management, ARIA only when necessary. Files an issue when the developer reaches for a div instead of a button.
API & Data Integration Lead
TanStack Query, RTK Query, SWR, tRPC, GraphQL clients. Owns the contract between frontend and backend so neither side ships broken JSON at 5pm Friday.
You See Everything. In Real Time.
Every Pillai Infotech project comes with a dedicated client dashboard. Kanban boards, live logs, test results, meeting notes — it's all visible the moment it happens. No status-report theatre, no "we'll get back to you", no surprises at the demo. You work with us like you work with your own team.
Kanban Board, Live
Every epic, every story, every task — visible on your dashboard. Drag, comment, reprioritize. It's the same board our team works from.
Documented Everything
Every decision, spec, API contract, and architecture diagram lives in the dashboard. Searchable, versioned, linked to the tasks they shaped.
Live Logs & Test Results
Build logs, deployment logs, test suite results — streamed to your dashboard the moment they run. You never have to ask "did the build pass?"
Meetings → Tasks, Automatically
Every meeting is recorded, transcribed, and every action point is auto-converted into a tracked task assigned to the right person. Nothing gets lost between calls.
Sprint Burndown & Velocity
See exactly how much work is done, how much remains, and our velocity over time. If a sprint is slipping, you see it the same moment we do.
Comment, Approve, Decide — In-Place
Comment on any task, approve designs, sign off on specs, and raise blockers directly in the dashboard. Everything tied to the work, not buried in email threads.
React Apps We Know How to Ship
We pick the React shape that fits the problem — SPA, SSR, SSG, or RSC.
🖥️ SaaS dashboards
Multi-tenant admin UIs, complex tables, charts, filters, role-based UI. Built with TanStack Table, virtualized lists, and a state model that survives 200 widgets on one screen.
🛒 E-commerce storefronts
Next.js commerce, ISR, edge caching, Stripe / Razorpay checkout, headless CMS. Lighthouse 95+ on mobile, because that's where the conversions are.
📰 Content & marketing sites
Next.js or Astro, MDX, headless CMS, sub-second LCP, perfect SEO scores. Built so the marketing team can ship landing pages without filing a ticket.
📊 Internal tools & admin panels
Form-heavy CRUD, audit trails, RBAC. We use the boring tool (RHF + Zod, TanStack Table, Radix) because internal tools are about reliability, not novelty.
🎮 Realtime & collaborative apps
WebSockets, CRDTs, Yjs, Liveblocks. Cursor presence, optimistic updates, conflict resolution. The hard parts that make or break a collaborative product.
🧩 Embedded widgets & micro-frontends
Sandboxed React widgets you embed on third-party sites, or Module Federation setups for teams shipping independently. Versioned, isolated, observable.
The React Stack We Use
We default to boring, proven choices. Novelty has to earn its way in.
Core
UI & Styling
State & Data
Quality & Delivery
A Six-Stage React Delivery Process
Built so the codebase is still healthy in year two, not just demo-day pretty.
Discovery & Architecture Call
SPA or SSR, Next.js or Vite, REST or GraphQL, what does state look like, who owns the design system. Decided in week one, in writing, with trade-offs.
Foundation Sprint
Repo, CI, lint, format, test runner, design tokens, component library skeleton, auth scaffolding, error boundary, analytics. Two weeks of unsexy plumbing that pays back forever.
Vertical Slice Builds
One end-to-end feature shipped per sprint, behind a feature flag. Real data, real auth, real error states. No big-bang reveal.
Performance & Accessibility Pass
Bundle audit, route-level code split, image strategy, Lighthouse run in CI, screen-reader pass, keyboard pass. Numbers, not vibes.
Hardening & Launch
Cross-browser pass, error monitoring wired up, 404/500 pages, robots/sitemap/OG tags, analytics, consent banner, smoke tests in production.
Post-Launch Monitoring
Weekly review of LCP, INP, CLS, error rate, bundle size. Hotfix process ready. Ecosystem patches (React/Next majors, security advisories) scheduled.

Honest Answers to React Reality Questions
The questions every smart buyer asks before signing. Here's what we tell them.
Next.js, Remix, Vite, or Astro?
Depends on the app. Marketing or content site — Astro or Next.js (App Router). SaaS dashboard with auth and lots of client interaction — Vite + React Router or Remix. E-commerce or anything SEO-critical with dynamic data — Next.js. We benchmark the trade-offs against your actual product, not against Twitter trends, and we'll tell you when you don't need a framework at all.
Do we need Redux? Zustand? Recoil? Context?
Most apps need much less global state than they think. We default to TanStack Query for server state, React state + Context for local UI state, and Zustand only when there's genuine cross-tree client state. Redux Toolkit is fine when the team already knows it. We don't pick the state library to feel modern — we pick the smallest one that solves the problem.
JavaScript or TypeScript?
TypeScript. Always. Strict mode, no `any`, no `@ts-ignore` without a comment. The cost is a week of ramp-up. The benefit is catching half your bugs in the editor and onboarding the next developer in days, not months. We don't take JavaScript-only React projects anymore.
Server Components — production-ready?
Yes for content-forward apps on Next.js App Router. Less so for highly interactive dashboards where the client/server boundary becomes a foot-gun. We use them where they win and we're honest when they don't. We won't ship a half-RSC half-client mess that nobody can debug.
How do you handle forms?
React Hook Form + Zod for the schema, every time. Server-side validation with the same Zod schema where possible. Accessible error messages, focus management on submit, optimistic UI when it makes sense. Forms are where most React apps actually live — we treat them as a first-class concern.
How do you keep the bundle small?
Route-level code splitting from day one, dynamic imports for heavy widgets, tree-shaking audited with rollup-plugin-visualizer or @next/bundle-analyzer, no Moment, no full lodash, no three icon libraries. We set a per-route budget in CI and break the build when it's exceeded. It's the only way to keep it honest.
What about accessibility?
WCAG 2.2 AA is the bar. Radix or React Aria primitives so the keyboard and screen reader behaviour is correct out of the box. Axe in CI, manual screen reader passes before launch, focus management on route changes. We don't treat a11y as a phase 2.
How do you handle design system / component library?
shadcn/ui copied into the repo and customized with your design tokens, or a Storybook-driven internal library when there are multiple apps. We don't reinvent buttons, modals or selects — those are solved problems. We invest the time in the components that are actually unique to your product.
Can you take over an existing React codebase?
Yes — that's a lot of what we do. We start with an audit (architecture, dependencies, tests, performance, accessibility), give you a written rescue plan with priorities and effort, then execute it incrementally. No "burn it down and rewrite" unless the audit genuinely says so, and we'll tell you honestly when it does.
Can you sign an NDA before we share details?
Always. NDA before the first call. Source and design assets stay under your control. Happy to work inside your tooling and your repo if compliance requires it.
