Where to find everything
Raghav Bansal
Full Stack + AI, building SaaS products
Summary
I'm a self-taught full stack developer who learns by shipping - Raag, TradeX, and Kosma are the proof. Lately that means exploring what AI can actually do for everyday workflows, one real project at a time.
Experience
Kosmakosma-ai.vercel.app
2026 - PresentSolo builder - full stack
- Built an AI change intelligence system that reviews prompt and model changes before they ship - finds comparable historical executions of an agent, replays the candidate change against them, and returns a Blast Radius Diff with a Ship, Modify, or Block verdict.
- The full core loop runs end to end against a real database - self-serve onboarding, GitHub sign-in with real repo activity, and 45 backend tests passing, not mocked.
Raagraag-health.vercel.app
2026Solo builder - full stack + AI
- Built an AI-powered personal health OS from scratch - auth, billing, and a document-parsing pipeline.
- Wired Claude into the app as an assistant that answers questions grounded in a user's actual records, citing its sources.
TradeXusetradex.vercel.app
2025 - 2026Solo builder - full stack
- Shipped a real-time stock tracker with live TradingView charts and Finnhub market data.
- Built a background job pipeline with Inngest to fire email price alerts automatically.
Focus areas
Full stack development
Shipping products end to end - from schema to ship button, not just prototypes.
Applied AI & ML
Training and fine-tuning models myself, not just calling an API and calling it AI - understanding what's actually happening underneath.
Research, implemented
Picking a paper and actually building what's in it, instead of stopping at the abstract - that's where the real understanding happens.
Open source
Contributing back whenever I find the itch to - small fixes count too.
