Analytics & Decision Sciences professional. 25+ years in the trenches of analytics and data science, delivering $23M+ in signed-off impact. Builder of the AI micro-apps portal TigZig.com. Individual contributor, 100% hands-on. Ex-derivative trader. Always in operator mode.
Tactical Ops, execution-first: I write the code (Claude now), build the models, automate the workflows, and deploy the tools. Mostly full-stack now - React/Vite, FastAPI, Postgres/DuckDB, or whatever stack the team runs on.
TigZig.com is my proof in the open: 40+ live tools, plus MCP servers and data APIs running public on the internet, no-auth, taking real traffic. That is the security and the full-stack capability shown live.
After decades driving impact in large corporates, I now focus on practical AI for small and medium businesses.

How I Work
Two kinds of engagement. Sessions are one to one over screen share, worked on your own real problem rather than a demo. Execution is scope-based build work, and every sprint runs to an hour cap you approve before it starts.
Billed on brain time rather than the clock. The repo and the documentation sit with you throughout, so you can stop, pause or take it over at any point. It goes live early, with real users on it well before it is finished.
Work with me - rates, the engagement sequence, examples from real engagements, and what I do not take on.
