Building AI systems, full-stack products, and documenting everything I learn.
Hi, I'm Yashwanth — welcome to my space. I love to build stuff, and write about what I explore along the way. Hit me up if you want to connect.
Currently
- →Neural networks, from the math up
- →RAG & evaluation for Bloom IQ
- →Robotics, new territory
- →Go, for the parts TypeScript shouldn't do
- →Open to engineering roles
01Recent writing
All writing →What separates an AI agent from a chatbot, why agents need tools, and how to build a two-model multi-agent swarm in LangGraph with state, nodes, and a loop that stops.
How a Code with Antonio tutorial turned into Relay, an n8n-style engine with a tool-calling AI agent, encrypted credentials, and replay, on Inngest and React Flow.
How Kortex's FastAPI agents get their output back into Postgres without ever touching the database themselves, routed through Inngest events and a shared-secret internal API on the Next.js side.
How Kortex turns a topic into a full, quiz-gated course with three AI agents and an event-driven pipeline
02Selected projects
All projects →A secure, containerised AI assessment platform for university examination systems — curriculum-aligned question generation that never sends data off-premise.
A visual workflow automation platform in the shape of n8n — 13 node types, a tool-calling AI agent across 8 providers, and every run executed for real as a durable Inngest function.
Full-stack and AI engineer — I'd rather ship the thing than just prototype it. If something here is useful to you, or you think I got something wrong, I'd like to hear about it.
