Analytics & Decision Sciences professional. 25+ years in the trenches of analytics and data science, delivering $23M+ in signed-off impact. Individual contributor, 100% hands-on. Ex-derivative trader. Always in operator mode.
Execution-first: I write the code, 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 full-stack capability shown live, not claimed on a slide.
After decades driving impact in large corporates, I now focus on practical AI for small and medium businesses.
