Rahul Chourasiya
Full-Stack AI & Systems Engineer
I architect end-to-end production systems where artificial intelligence, high-throughput web platforms, and human-centric design converge. From enterprise conversational AI at Kotak Mutual Fund to open-source packages powering thousands of developers, I build software that performs under real-world scale.
How I Engineer Systems
Architecture isn't just writing clean syntax—it's managing tradeoffs, guaranteeing availability, and delivering measurable business outcomes.
Production AI & Agent Workflows
RAG • Tool Calling • Streaming Runtimes
Large Language Models are only as valuable as the systems engineering wrapping them. I build resilient conversational agents, structured JSON schema generators, streaming SSE pipelines, and deterministic guardrails that reliably operate in high-stakes production environments like Kotak Mutual Fund.
FinTech-Grade Security & Systems
Digital KYC • Atomic Transactions • SEBI Standards
Building for finance demands zero-trust state verification, idempotent API contracts, and rigorous error budgeting. From mutual fund folio switches and SIP engines to identity verification, I design distributed systems where data integrity and user capital are strictly protected.
Spatial 3D & 60 FPS WebGL
Babylon.js • Accessible Wayfinding • Canvas Math
Crafting multi-block indoor navigation (Mapinger) requiring real-time accessible routing (elevator prioritization, wheelchair pathfinding), complex coordinate transforms, and 60 FPS rendering on budget mobile hardware without CPU throttling.
Open Source & Developer Tooling
10K+ Downloads • OpenAPI • Edge Runtimes
Creator and maintainer of @rcmade/hono-docs, an open-source documentation framework for Hono.js edge APIs with over 10,000 installs. Passionate about developer ergonomics, type inference, and reducing boilerplate across the software lifecycle.
