Experience

Centre of Financial Technologies (since March 2026)

FTData DBMS (PostgreSQL)

Primarily working on a CDC sink from OLTP to ClickHouse, which will serve as our OLAP engine, and live-transferring tables from one DBMS instance to another. Also fixing bugs and improving performance of the existing codebase, supporting new extensions and migrating our features to PG18. Never thought I'd be working on this kind of project, but it's a great opportunity to improve systems programming skills.
