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.
