About

Shivank Bhardwaj

Who I am, where I've worked, the stack I use day to day, and what I'm looking for next — the short version, with the full timeline below.

I'm a Software Engineer who builds backend systems and production AI agents — and ships them end to end, working directly with the people who'll use them.

Over the last four years I've worked across aviation, finance, and energy — Cognizant, Universal Weather & Aviation, Indigo, BlackRock, and now Bidgely — integrating external partner systems, migrating live databases, building a back-office app from scratch in two months, and owning billing logic end to end. The throughline is ownership: sit with the stakeholders, turn messy needs into UI flows and API contracts, then ship and stand behind it in production.

Most of my recent work sits where backend engineering meets applied AI — internal agents with tool calling and retrieval, eval suites that gate every release, and personal projects in multi-agent systems, MCP, and production RAG. I care about the unglamorous parts: evals, idempotency, observability, and writing the decision down so the next person doesn't have to reverse-engineer it.

Open to Forward Deployed, backend & applied-AI engineering roles. If that kind of work resonates, I'd like to hear from you.
