What I'm looking for

I want to build production-grade backend services and APIs in small autonomous teams, with real ownership of customer lifecycle and acquisition systems. I care about measurable quality via test automation, pairing/code review, and strong observability.

I’m a backend-focused software engineer with hands-on production experience building robust backend services and APIs across banking, e-commerce, and ad-tech domains. I’m especially energized by event-driven distributed systems where reliability and performance can be proven.

I’ve worked on production-grade quality by delivering 40+ automated integration tests over Kafka and PostgreSQL, and by monitoring systems via Kibana to cut incident detection from hours to under 15 minutes. I also validate event-streaming integrity, catching data-consistency defects before production.

In Go, I build services that stand up under load—using Kafka pipelines, gRPC, and resilient API patterns—while leaning hard into test automation. My personal projects include a production CLI data pipeline and a JWT-based SSO microservice with strong edge-case coverage and p95-focused performance.

I thrive in small, autonomous teams with real product ownership. I actively balance quality and progress, pay down technical debt, and collaborate through pairing, code review, and learning from senior engineers—so teams can ship confidently.
