Tools and demonstrators I have built and released as open source — primarily focused on ClickHouse, performance tuning and agentic analytics.
ClickHouse query log analysis and performance tuning
QueryDog is a single-container open source tool for diagnosing slow ClickHouse queries and tuning your instance for maximum performance. It visualises the query log on a timeline, drills into execution plans, exposes resource consumption per query, surfaces background merge and mutation activity, and pulls errors and warnings out of the system logs. It is the tool I reach for whenever I need to understand what a ClickHouse cluster is actually doing.
Agentic analytics across financial services scenarios
A demonstrator showing how agentic analytics can be applied across financial services — capital markets, retail banking, insurance, fintech and compliance. Each domain ships with sample agents and conversations that go beyond text-to-SQL into scenario modelling and strategy development. Bring your own Anthropic key and ClickHouse credentials (a free ClickHouse Cloud account works) and the demonstrator is ready to run.
