Rajat Yadav

About

I build software that tries to feel considered.

I'm Rajat, a full-stack developer based in India, working across product engineering, DevOps and applied AI. Over the last couple of years I've shipped complete systems: an ERP platform for a business (finance, school, learning, CRM, HR and payments), a roadside-assistance marketplace with customer and driver apps, a fintech expense-splitting app with a shopkeeper khata ledger, a queue-driven e-commerce backend, and an AI agent that orchestrates open source contributions.

I work across the whole stack — Python (FastAPI, NestJS, Frappe), TypeScript (React, Next.js, React Native, Flutter), and the infrastructure around it (PostgreSQL, MongoDB, Redis, Docker, Railway, AWS). I care about the parts that make production software trustworthy: idempotent webhooks, atomic state transitions, audit trails, and secrets that never reach git.

When I'm not shipping a product, I'm contributing to open source — 55+ pull requests across CCExtractor, Zulip, SveltyCMS and more — or tinkering with LLM integrations and agent workflows.
