About Me

I am Paalamugan, a full stack engineer in Chennai with 9 years on Next.js and TypeScript products. I take the whole slice: the React app, the Node service behind it, the Postgres schema both depend on, and the CI that ships them.

At Glidewell Dental I shipped payment scheduling and AutoPay in Next.js, tRPC and TanStack Query, and built the lab management system that 500+ dental labs use every day. Before that, Node microservices for General Motors at 99.9% uptime, and four SaaS products at NamLabs serving 50,000+ users.

Right now I am building a multi-tenant CRM for a real-estate builder: Next.js 16 and NestJS on Prisma and Postgres, with 233 row-level security policies enforcing tenant isolation across 32 models, covered by 208 Vitest files. I publish the @paalstack React packages I build it with.

What I do all day

Frontend

Frontend

React 19, Next.js and TypeScript, with Tailwind and a design system built on Radix-style primitives. I care about bundle size, Core Web Vitals and keeping the Lighthouse score above 95.

Backend and data

Backend and data

NestJS and Express services on Prisma and Postgres. Row-level security for tenant isolation, Redis for pub/sub, and uptime I can put a number on: 99.9% on the General Motors platform.

Platform

Platform

pnpm and Turborepo monorepos, Vite Module Federation and single-spa for micro-frontends, GitHub Actions for CI, and Vitest and Playwright suites that actually run before merge.
