What I do
- Backend systems that hold up under load. Spring Boot and Node.js services, event pipelines on Kafka, search on Elasticsearch, and the data models underneath them.
- SaaS products, end to end. Auth, billing, multi-tenancy, background jobs, observability, and the dull details that decide whether a product survives its first big customer.
- AI-accelerated delivery. I use coding agents and LLM tooling to move fast while keeping the software reliable and the quality bar very high.
