Senior🎓
Top SchoolAleksandar Osenov is a Technical Lead with 9 years of experience building and guiding teams on high-performance Java and full-stack projects, currently leading engineering at Sqilline Health from Bulgaria. He combines deep Java/Spring expertise with modern front-end skills in TypeScript and React, and has driven significant system improvements like migrating Kafka to Redis Streams and cutting GCP costs through performance and storage optimizations.
