Own developments
End-to-end data projects
Projects where I owned the full cycle: defining the question, obtaining and cleaning the data, writing the code and publishing a tool someone else can use.
These are personal projects: built outside working hours, for fun and to practice tools. The professional experience is in the work tab.
Rental finder
A system that consolidates rental listings from three sites every day, deduplicates and geocodes them, and publishes them in a viewer with filters, metrics and history.
Nine years of activity data
Processing 2.74 million Apple Health records with Python: streaming read of a 1.2 GB XML file, pandas aggregation and a dependency-free HTML report.
Betting analysis: the house always wins
A betting log and analysis app that computes returns with confidence intervals and compares them against zero-edge simulations, to tell luck from skill.
Job search engine with AI agents
An agent system that collects job openings from several sites, scores them against a profile with explicit criteria and keeps a record of every application.
Other published work
Smaller prototypes, all online and with their code available.
Professional experience
Work, projects and consulting
Official statistics, think tanks, consulting and public education. Each project opens with what I did, the tools and the results.
