Hi, I'm Prathmesh. I build AI products end-to-end.
From LLM tool calling agents and RAG pipelines to the full stack that ships them. Currently sole engineering a live AI video SaaS serving thousands of paid users, contributing to open source, and prototyping at the edge of what LLMs can actually do in production.
Rebuilt a UK client's AI video generation platform as the sole engineer from unstable prototype to a product serving 1,800+ users. Own the full stack end-to-end: Next.js 16 + React 19 frontend, tRPC + Drizzle + Postgres backend, AWS Lambda-powered rendering, plus auth, payments, AI pipelines, and infra. Shipped a Remotion Lambda pipeline with durable job lifecycle via RunPod webhooks, a multi-provider AI SDK v6 setup (Gemini, Replicate, RunPod, Inworld Voices, Grok Imagine), and a remote MCP server so the product runs inside Claude one of the earlier MCP apps in the AI video space.

Joined a team building the next generation of skills-based hiring and took primary ownership of the recruiter-facing experience. Led the recruiter filter + candidate heatmap system on get.proofofskill.org with URL-persisted filters and deterministic share-link rebuilds. Shipped the "Hire" swipe app end-to-end (swipe UI, landing page, Mixpanel + CleverTap + Tawk funnel), migrated skills.cv candidate recording from direct S3 uploads to AWS IVS live streaming, and rolled out a jscodeshift codemod replacing 226 files of console logs with a Sentry-aware logger. Also prototyped an AI recruiter chat agent on AI SDK v5 + GPT-5 with tool calling.

Two independent projects one exploring what an AI-first email client could look like, the other a mission-critical government delivery with a hard deadline. Built a full AI email + calendar client solo in Next.js 15: RAG over the inbox with pgvector, AI summaries and reply drafts via Gemini, a cmdk command palette, and Google Calendar + Meet integration. Then delivered an event accreditation + ID-card platform for a FIFA International friendly in Shillong, 1,500+ printable IDs via a PDF + canvas + sharp overlay pipeline with role-gated approvals.

Stack
What I actually reach for.
no framework collecting
I mostly ship using AI first tooling with TypeScript on Next.js, lean on Postgres + Drizzle for data, and deploy to AWS. Everything else is a tool, not a religion.

I'm currently open for full-time or contract work. If you're building something with LLM agents, RAG, MCP, or the full stack around them, send me an email or put 15 minutes on my calendar.
