- Build and maintain high-performance APIs and data validation patterns that enable frontend and data engineers to deliver low-latency product experiences.
- Optimize complex data workflows across PostgreSQL and ClickHouse to ensure financial correctness and observability for clients making million-dollar decisions.
Who this is a fit for

- Expert-level SQL skills and experience managing data-heavy applications using both transactional (OLTP) and analytical (OLAP) databases like ClickHouse.
