Software Engineer — Full-Stack Developer

I build full-stack web apps end to end, from database models to React interfaces. At Louisa AI I shipped the GitHub integration, workflow APIs and Slack notifications for a release automation platform.

About

Schema to last component.

I'm a full-stack developer who likes owning a feature from the database schema to the last React component.

Outside work I build tools that make software more trustworthy: retrieval bots that cite sources, tests that expose stale coverage, and streams that never silently drop events.

Discipline: Full-stack development
Most recent role: Software Engineer Intern, Louisa AI
Degree: B.E. Computer Science and Engineering, Jadavpur University
Core stack: React, Next.js, Node.js, Hono, Bun
Data: MongoDB, PostgreSQL, Redis

Experience
