About

Engineer who ships, not just writes code

Full-stack engineer who ships production SaaS — React, Next.js and TypeScript on the front, Node and Python on the back. I turn ambiguous problems into shipped features: AI-powered OCR pipelines, real-time dashboards, and APIs built to scale. Currently building at TechRays Labs, and always architecting the next thing.

I care about the boring parts that make products real: query indexing that cuts latency, CI/CD that ships without downtime, and tests that let you refactor without fear. Outside of work I'm deep in DSA, system design, and building my own products.

What I Do

End-to-end engineering, built to ship

From the first wireframe to the production deploy, I work across the whole stack — turning ambiguous ideas into products that scale and stay maintainable.

01

Full-Stack Product Engineering

Designing and shipping production SaaS end-to-end — React/Next.js front ends wired to typed APIs, with the polish users feel and the architecture teams can maintain.

  • React, Next.js & TypeScript UIs with reusable design systems
  • Server components, code-splitting & memoisation for speed
  • Accessible, responsive interfaces that ship fast
02

Backend & APIs

RESTful microservices and data layers built to scale — auth, integrations, and the unglamorous reliability work that keeps products up.

  • Node.js / Express & Python / FastAPI services
  • JWT / OAuth2 auth across 5+ third-party integrations
  • PostgreSQL & MongoDB schema design and query optimisation
03

AI-Powered Features

Turning models into product — OCR pipelines, RAG assistants and AI workflows wired into real user flows, not demos.

  • OCR extraction pipelines (~92% field accuracy)
  • RAG over vector DBs with grounded, cited answers
  • LLM features wired into production UX
04

DevOps & Deployment

Ship continuously and sleep at night — Dockerised CI/CD, cloud infra and zero-downtime releases.

  • AWS (EC2, S3, RDS) & Azure deployments
  • Dockerised GitHub Actions CI/CD pipelines
  • Nginx, monitoring & zero-downtime releases

Things I'm building

A growing suite of products — from a personal productivity OS to real-time and AI systems. Some are live, the rest are inbound.

LifeOS — Operating System for Self

In Progress

A single command center for your life. It unifies habits, goals, health, finances and learning into one signal, then turns that signal into AI weekly reviews that surface what actually moved the needle — so you optimise yourself like you'd optimise a product.
