Summary

Rockstar🎓
Top SchoolEvaldas Buinauskas is a seasoned database and search engineer with 11 years of experience building high-performance data systems and search infrastructure for market research and consumer platforms. Based in Vilnius, he currently focuses on search, observability, and performance at Vinted, where he migrated search logic to Rust, optimized Elasticsearch throughput, and built an open-source Elasticsearch DSL in Rust. He has a strong track record modernizing legacy data pipelines—moving indexing from cron jobs to streaming to cut item discoverability from minutes to seconds and shrink reprocessing from weeks to hours. Previously he led and grew a team at Euromonitor, standardizing data models, eliminating T-SQL technical debt, and delivering cloud-native services with CI/CD. Known for pragmatic mentorship and hands-on workshops, he blends deep database know-how with practical tooling to let non-technical teams influence search relevance and business metrics. A curious, active learner, he pairs analytical rigor with product-oriented engineering to turn data complexity into measurable outcomes.
