# about

piotr sienkiewicz

# currently

work: On OLX's GenAI team, building the backend for a real-estate search chatbot. Python, Go, Next.js & AWS.
founded: tripled.pl — a 3D-printing print farm, focused on turning ideas into physical prototypes.
founded: House of Beer — a craft beer bar & microbrewery I started 15 years ago with my wife. Still pouring; I'm less hands-on now.
off-clock: FPV drones, Arduino, ESP32 & custom electronics, 3D printing — I like building things.

# previously

20+ years in the field — software & solutions architect roles across Poland, the UK and the US, from C/C++ and PHP to full-stack, then into data and ML.

Obido: Data & ML at Obido, later part of the OLX Group. Built a product for Poland's primary housing market — ML models for customer churn and time-to-sell, geospatial analysis, and floor-plan similarity search via trained vector embeddings.
analytics: Tracking pixel, user-behaviour analytics and a recommendation system.
teaching: Taught 3D Studio MAX and game development on the Quake engine, using DigiPen's curriculum.
early: License-plate recognition system and a third-person shooter on Unreal (UDK); 3D modelling in the Rainbow Six modding scene.
