About
I'm a hands-on engineer and architect for data platforms where the numbers have to be right to the cent, and for the AI-agent infrastructure that lets a small team run them safely.
Since 2023 I have worked at Wildberries, one of the largest marketplaces in Eurasia. There I am the tech lead of a 12-engineer team that owns billing and settlements data for millions of sellers: tariffs, logistics and storage fees, acquiring, compensations and contract documents, on Greenplum (about 100 TB), ClickHouse, PostgreSQL, Kafka and Airflow. In 2026 I built the team's AI-agent platform and started applying formal methods to its billing logic.
I am also the co-founder and CTO of Groupsi, an online group-therapy platform for school and university students in Brazil.
Before that I was an engineering manager at a Swiss crypto fund (the team grew from 6 to 20), team lead of a 10-engineer analytics platform for Russia's Federal State Statistics Service, a back-end developer at Sketchfab in Paris, and a builder of B2B SaaS and API-billing products from zero.
How I work
- I work with coding agents and verify everything they produce. Direction, verification and accountability are mine.
- I look for the mechanism behind a problem, not just the symptom, and I measure before and after.
- I put safety in capabilities and permissions, not in instructions.
Languages and location
English, Spanish and French (C2), Portuguese (B2), Russian (native). I work remotely across the Americas (UTC−3 to UTC−6).
