Senior🎓
Top SchoolCosmin Mavrichi is a senior backend engineer with 8 years of experience designing and operating high-throughput distributed systems using Java and Kotlin. He currently delivers GCP-based data pipelines processing 10M+ betting events daily and builds Spring Boot microservices for healthtech on AWS, combining strong ownership with pragmatic engineering practices like clean architecture and high test coverage. Cosmin has a track record of improving reliability and performance—implementing Kafka DLQs and retries to cut event loss ~80%, optimizing BigQuery queries to reduce runtime 40%, and introducing log-based alerting that cut undetected incidents by 60%. He’s comfortable across clouds (GCP, AWS, Azure), has migrated platforms and infrastructure with Terraform, and pushes for measurable operational gains rather than vague optimizations. Based in Bucharest, he’s open to remote contracts across the UK and EU and brings a language-agnostic curiosity that spans JavaScript, Go and Python alongside his core Java/Kotlin expertise.
