Summary
Cosmin Bucur is a Senior Software Engineer with 11 years of experience building and modernizing large-scale backend systems, currently driving modularization and performance improvements at Mambu. He brings deep Java expertise (8–23), practical experience with Scala and Python, and hands-on ownership of microservice extraction, performance testing and production tooling across AWS and Kubernetes. Beyond coding, Cosmin mentors and teaches—creating end-to-end programming courses and serving as a technical lead trainer—so he pairs engineering craft with a talent for helping others learn. He’s comfortable across the stack (Next.js/React to PostgreSQL, Kafka, Redis) and in the full delivery lifecycle from CI/CD and GitOps to observability and security. A self-taught early adopter, he also practices life coaching and applies a disciplined, holistic approach to personal optimization that informs how he mentors teams and shapes developer productivity. Based in Bucharest, he excels at turning complex legacy codebases into modular, testable systems and building tooling that makes large codebases safer to change.
