Projects

The larger personal builds. Each one exists because I wanted to learn a specific shape of system end-to-end; the write-ups focus on decisions and trade-offs rather than feature lists.

FPL Pulse, weekly enrichment pipeline

AWS Lambda, Step Functions, S3, Anthropic Haiku and Sonnet, Langfuse.

A weekly LLM enrichment pipeline for Fantasy Premier League. Five collectors fan out across the FPL API, Understat, and news sources into a four-stage S3 lake; a Step Function drives enrichment over roughly 700 players per gameweek through Anthropic Haiku and Sonnet, cost-engineered to sit inside the AWS free tier with the Claude API as the only meaningful spend.

Scout Agent, agentic recommendations

LangGraph, pgvector, Lambda Function URL, SSE streaming.

The interactive plane on top of the FPL pipeline. A four-node LangGraph state machine (planner, tool_executor, reflector, recommender, looped up to three times) runs over a Neon pgvector store and streams transfer recommendations to the dashboard over Server-Sent Events through a Lambda Function URL. Shipped April 2026 after the OAC-on-POST landmine cost me an evening and an ADR. Read →

Knowledge vault and personal plugin

Plain markdown, Claude Code plugin, no embeddings, no MCP, no daemon.

A curated personal knowledge base read directly by Claude Code via Read, Grep, and Glob. Started as a hybrid FTS5 plus LanceDB MCP server with an Ollama embedding pipeline, then deleted entirely once the vault was small enough to fit in context. The deletion is the point. Read →

Tube Race, a daily navigation game

React, TypeScript, Dijkstra, a Python + TfL Open Data pipeline, static on AWS.

A change of shape from the rest: a daily fog-of-war puzzle on the London Underground, where you navigate a fogged map to a target and get scored against the Dijkstra-optimal route. A greedy solver measures how hard each day is, and every station comes with its opening year, traffic, and a fact worth knowing. No backend, no LLM, no per-play cost. Play it · writeup →
