My public work - 60 demos, 57 with test suites

My public work hub: 60 runnable demos across ETL, web scraping, document AI, RAG, analytics, machine learning, developer tooling and robot data.

Every demo ships the output its own code produced, so the numbers on each page are numbers you can reproduce rather than claims you have to take on trust. All 60 are public on GitHub, and 57 of them carry test suites.

How I work. Verification is part of the build rather than an afterthought: confidence scores, checks against source, and a human-review queue for anything uncertain. Anyone can get a model to emit JSON; what a team pays for is output it can trust and sign off on.

What ships with a project. Tests, and a plain-English handover document, so the client never has to touch the code to understand what it does or why it stopped.

How I work with clients. Fully async, in writing - no live calls. Fixed price by scope where possible, so the cost is known before the work starts.
