III.
Approach
How I work
Five principles
I.
Ship the foundations firstAuth, error states, empty states, observability. The interesting work sits on top of the boring work doing its job.
II.
AI as a tool, not a featurePick the right model for the job — OpenAI, Claude, Gemini — and design around its failure modes, not its demo.
III.
Performance is a UX decisionA 40% drop in API latency at Blurock changed how the product felt. Measure first, optimise second, ship third.
IV.
Frontend is a data problemState, types, and data flow decide whether an interface feels reliable. Components are just the surface.
V.
Working code beats good intentionsTwo internships, four shipped products, and a final year of CS. The receipts live below this page.

Shipped an AI-first CRM where the form fills itself

Wrapped up an AI-first CRM for pharma field reps — a read-only interaction form driven entirely by a LangGraph agent. Reps describe a visit in plain English and the assistant extracts, edits, and saves every field. Eight tools, full CRUD to Postgres, running on a Groq LLM.

Wrangling LangGraph tool routing

Spent the day getting a LangGraph agent to route cleanly across eight tools. The small models kept looping instead of stopping; gpt-oss-20b turned out to be the sweet spot—reliable routing without the 70B price tag. The real trick was a strict system prompt and an edit tool that merges corrections instead of overwriting the whole form.

02 JUL 2026CODE

Learning FastAPI the right way

Spent a few hours understanding FastAPI beyond CRUD examples—dependency injection, request validation with Pydantic, async endpoints, middleware, and project structure. Feels like a much cleaner fit for AI backends than Flask.
