About Me

Param Vansjalia
Open to contract work

Hi, I'm Param - a Full-Stack Developer.

I build production applications on Angular and NestJS, with hands-on distributed systems work across Kafka, Redis, MongoDB, and PostgreSQL. At Kevit Technologies, I ship features end-to-end across a multi-tenant chat automation platform serving 2,000+ business accounts and 5 million+ daily messages.

I recently led a 5-month initiative to make our production codebase agent-operable - designing a layered context architecture, a reusable subagent library, automated error triage, and hook-based visual regression testing. I care as much about the systems that build software as the software itself.

I'm based in Rajkot, Gujarat, and available for contract work with daily overlap into US Eastern and UK hours.
