Beat 01 / Personal · Ummaly

Training my own model.

A custom PyTorch halal-classification model for Ummaly. Trained on an ingredient and additive corpus, packaged for mobile inference, and shipped inside the app so users get an answer offline, in milliseconds, without a round-trip to a server.

On the AI team at my full-time employer: wiring production LLM features into a large .NET platform. Prompt orchestration, retrieval, eval harnesses, MCP integrations, and the everyday Azure plumbing that keeps it all standing on Monday morning.

Beat 03 / Tooling · MCP

MCP & Claude, daily.

I write MCP servers and custom skills the way I used to write shell aliases: small, sharp tools that compose. Claude is the co-engineer that reads the repo, drives the workflow, and hands the keyboard back when the decision is mine to make.
