What I'm looking for

I’m looking for a backend role in analytics or event-driven products where I can own service architecture end to end, build Kafka/CDC data pipelines, optimize PostgreSQL with caching, and strengthen observability and delivery reliability.

I’m a Backend Developer with 6+ years of commercial experience building services and data flows for fintech, payments, streaming data, and analytics products. I own backend delivery end to end—service design, implementation, integrations, testing, documentation, and production-minded maintainability.

My core strength is data-heavy systems: Kafka and CDC pipelines, aggregation logic, PostgreSQL optimization, Redis caching, and ELK-based search and reporting. I bridge product and engineering needs by translating business reporting requirements into APIs, data models, dashboards, and scalable microservice architecture, with a strong focus on reliability, observability, and lowering delivery risk.
