01 · ABOUT
Backend-first engineer, agent-minded builder.
I'm Paramveer — a full-stack developer and agentic AI engineer with a strong backend focus. I build scalable web apps, production RAG pipelines and LLM agents with the unglamorous parts done right: provenance, evals, observability and infra as code.
As a GSSoC '24 project admin I led 50+ contributors and kept deploys green at zero downtime. These days I'm building AI systems in public — open source, documented trade-offs and all.

Edge to agent: this portfolio is 100% Astro — zero client JS framework, ships from the edge. My day job is RAG pipelines, not landing pages.
