Summary
👤
Senior🎓
Top SchoolDaniil Roman is a Senior Backend Engineer based in Berlin with 9+ years building Java/Kotlin systems focused on distributed, high-load backends. He has hands-on experience designing real-time ETL pipelines and high-performance search systems at scale using Kafka, Debezium, Elasticsearch, and Cassandra, and has driven measurable product metrics like a ~7% uplift in transactions. His background spans team leadership, on-call reliability work, and cross-functional initiatives—from fiscalization projects to SEO-driven backend optimizations—giving him a broad, product-aware engineering lens. Academically grounded with a Master’s in Data Science, he also brings practical tooling experience (Grafana dashboards, distributed caching, dead-letter queues) and a habit of documenting learnings via technical articles. He’s as comfortable refactoring SQL-heavy systems and building compiler-style migration tools as he is shipping customer-facing backend features.
