Systems & Backend Engineer

Gurugram, India

I build backends — the unglamorous parts that still have to hold up.

Currently building: Backend services at a stealth startup
Currently learning: Inference engineering & ML systems

Selected projects

All code on GitHub

A distributed key-value store in Rust — hands-on with consensus, replication, and keeping data sane when nodes disagree.

Experience

Stealth Startup

Backend Developer Remote

Jan 2026 – Present

Built the AI assistant on Next.js — UI and API routes in one place, fewer moving parts.
Quota system for API calls, tokens, and uploads — per plan, enforced cleanly.
Three microservices and subscriptions on AWS Lambda, connected with REST and queues.

More about the work

Integrated four services (subscriptions + three internals) so teams could ship independently.
Slack, HubSpot, Pipedrive, and email via custom webhooks so users can connect their own tools.

July 2025 – Dec 2025

Backend for attendance and employee tools that HR used day to day.
Contributed to an Electron + Next.js AI desktop app — mostly services, some UI glue.
Shared auth / SSO so one login opened the full product suite.

Tools I use TypeScript, Node.js, Next.js, Redis, PostgreSQL, AWS Lambda.
