👋 About me

I'm a full-stack software engineer with 3+ years of experience, based in Gurugram, India. I own features end to end, from MySQL schemas and backend APIs to the UI, across commerce, fintech and document-processing platforms, and I like turning ambiguous requirements into clean, scalable systems.

  • 🛒 Frontend lead on Ratio, a multi-tenant commerce platform. I've shipped storefronts for 7+ brands, plus Cardify, a drop-in product-card app that is live on 16 storefronts.
  • 🤖 I build AI-augmented engineering tools: multi-agent pipelines, MCP servers and approval-gated automation.
  • ⚙️ Strong on the backend: I design and ship APIs in Node.js / NestJS / Express and Python / FastAPI, model data in MySQL, build SSO and secure auth, and own AWS + Docker deployments.
  • ⚛️ And on the front: React and Next.js (App Router), TypeScript and Tailwind, with a focus on performance (100% Lighthouse scores on multiple production pages).

⚙️ Backend & architecture

What I've built and owned
APIs and services Node.js / NestJS / Express and Python / FastAPI services, BFF proxy layers over multi-service backends, and multi-tenant architecture
Data MySQL schema design and query optimisation for a large-scale document-upload platform, plus MongoDB
Auth and security Single Sign-On across frontend and backend, and secure custom document rendering
AI and document pipelines Backend APIs for large-scale PDF processing that structure financial documents for LLM pipelines, working with an AI team to lift response accuracy to 85–90%
Migrations and integrations Discount and reviews migration APIs that pull live data from Shopify into a custom data model with zero loss, plus a custom order-confirmation package, front and back
Cloud and delivery AWS (S3 and deployments), Docker containerisation in production, and CI/CD
