Say hello WRITING
Notes on growing
AI, teaching, and building products — written down so I actually understand them.
21 Jul 2026 Scout: an agent that decides where to look AI agents explained from first principles — tool calling, the decide-act-observe loop, and knowing when to stop — through a real research agent that chooses between arXiv and Wikipedia and answers with sources. 20 Jul 2026 The Writing Bed: answering from my own words Retrieval-augmented generation (RAG) explained from scratch — embeddings, chunking, vector similarity search and grounded answers with sources — built through a real tool that answers questions straight from my blog posts. 19 Jul 2026 Growing Sprout: a digital twin that knows its limits How to build an LLM chatbot that stays accurate: a from-first-principles look at system prompts, grounding, streaming and guardrails — and why the hard part isn't making a model talk, but making it refuse. 15 Jul 2026 Rebuilding Usama's corner of the internet Why I retired my old FastAPI portfolio for a static site with a proper brand — and what 'helping people and products grow' means as a design brief.
Let's grow something together.
Consulting, teaching, speaking, or a product idea that needs an AI brain — my inbox is open.
