Hi, I'm

Full Stack Developer

Turning complex operations into clean, automated software. From inventory systems to payment gateways — I build things that scale.

Scroll

I build tools that scale with precision.

Full stack developer with 4+ years building high-performance, production-grade systems — from a metro ticketing platform serving 50,000–100,000 daily users across 4 cities to procurement dashboards that auto-calculate reorder quantities from 4 sales channels simultaneously.

I specialise in taking messy, manual workflows and replacing them with fast, reliable software — Zoho integrations, multi-platform analytics, cloud infrastructure on AWS, and admin tooling teams actually want to use.

Capabilities
  • Full stack delivery — schema to UI
  • Business automation & workflow tooling
  • Payment gateways: Razorpay, Cashfree
  • Multi-platform data dashboards
  • Zoho CRM, Books & Inventory integrations
  • AWS infrastructure & CI/CD pipelines
