Full Stack Developer in Thane, open to product engineer roles

I build the systems restaurants actually run on. Multi-tenant SaaS, GraphQL APIs, and three POS integrations inside a seven-service TypeScript monorepo.

Selected work

Four things I owned end to end.

Every one of these shipped inside ChoosePOS, a multi-tenant restaurant commerce platform running on a seven-service TypeScript monorepo.

ChoosePOS01

Storefronts that deploy themselves

A no-code builder that generates a restaurant's site and pushes it live through the Vercel API. Nineteen section families, every one themed from CSS-variable design tokens the owner controls.

  • Next.js 15
  • Vercel SDK
  • Design tokens
Integrations02

Three POS platforms, one menu

Square, Clover and Toast wired in behind OAuth, with scheduled token refresh and bidirectional menu and inventory sync running on BullMQ workers.

  • OAuth 2.0
  • BullMQ
  • Webhooks
Pricing03

A price the client cannot argue with

Server-authoritative pricing resolves items, nested modifiers, discounts, promo codes, delivery fees and tax on the backend. No client-side price trust, and order creation stays atomic.

  • Fastify 5
  • TypeGraphQL
  • MongoDB
Async04

Everything slow moved off the request

An event-driven layer on BullMQ, Redis and SQS carries POS sync, transactional and marketing email, delivery dispatch to DoorDash and Uber Eats, and scheduled reporting.

  • Redis
  • AWS SQS
  • node-cron
