Backend APIs
Node.js with Fastify or Express, REST or GraphQL, request validation with Zod, pagination and versioning done properly, and rate limiting that survives real traffic.
TypeScript Full Stack Development — Node, PostgreSQL, Typed End to End
One language from the database row to the rendered component, with the types actually connected rather than re-declared in three places. I build TypeScript products where a schema change surfaces as a compile error instead of a production incident.

Who this is for
- Founders who need one engineer to own the whole stack and ship a real product, not a prototype.
- Teams with a JavaScript codebase that has outgrown itself and needs types, tests, and structure retrofitted.
- Products where auth, billing, or multi-tenancy have to be correct the first time.
What I deliver
Database & data modelling
PostgreSQL with Prisma or Drizzle — schema design, indexing, migrations that run safely against live data, and row-level security for multi-tenant products.
Authentication & security
JWT with refresh-token rotation, OAuth2/OIDC, passwordless and WebAuthn, session hardening, and the OWASP basics covered rather than assumed.
Typed frontends
React and Next.js App Router with Server Components and Server Actions, end-to-end type inference from the database through to the form.
Testing & CI
Vitest and React Testing Library for units, MSW for network boundaries, Playwright for the flows that would cost you money if they broke.

How we'll work together
01
Scope
Define the data model and the handful of flows that matter. 30-min call, free.
02
Foundation
Schema, migrations, auth, and CI first — the parts that are expensive to change later.
03
Build
Weekly sprints, each ending in something deployed you can click through.
04
Ship
Production deploy, monitoring, and handover with documentation and a typed API surface.
FAQ
How much does a full stack TypeScript build cost?
A focused MVP with auth, database, and a core workflow: ₹40,000-₹1,50,000. A larger multi-month product build runs ₹2,00,000-₹4,00,000+ depending on scope.
Can you add TypeScript to an existing JavaScript codebase?
Yes, and incrementally — allowJs on, strict mode off, then file-by-file with the highest-risk modules first. A big-bang rewrite of a working codebase is almost never the right trade.
Prisma or Drizzle?
Prisma for most teams: better migrations and a gentler learning curve. Drizzle when you want SQL-shaped queries and a smaller runtime, particularly on edge deploys. I pick based on your team, not fashion.
Do you write tests?
Yes, on the parts where a regression costs real money — auth, billing, and the primary user flow. I do not chase a coverage percentage for its own sake.
