Senior🎓
Top SchoolDarong Mean is a seasoned software developer with over a decade of professional experience and more than four years leading teams, currently based in Gothenburg, Sweden. He specializes in backend systems for FinTech and Open Banking, delivering resilient integrations, SSO solutions, and payment rails that process millions of transactions monthly. Comfortable across Clojure, Go, Java/Spring, Docker, and PostgreSQL, he has a track record of improving acceptance rates by up to 30%, cutting session times 20%, and reducing operational costs through pragmatic engineering. Darong blends hands-on implementation (instant refunds, SEPA/PSD2, Bankgiro/Plusgiro) with platform-level optimizations like migrating streaming jobs to Apache Beam to slash response times. He also brings strong observability and incident response experience—adding OpenTelemetry, OpenSearch, and PagerDuty workflows—to keep production systems reliable. A practical problem-solver, he often pairs technical upgrades with developer practices (CI, pair programming, Mikado) to raise team velocity and code quality.
