Kyiv, Poland
Summary
👤
Senior🎓
Top SchoolSergii Grebeniuk is an engineering leader and hands-on systems developer with 8+ years of professional experience building high-performance web and trading systems from Kyiv (now based in Poland). He led and scaled front-end engineering at Preply from a small team to 40 engineers, driving major stack migrations, CI/CD, deploy-blocking E2E testing, Core Web Vitals optimizations, and SOC-2 enabling security work that supported a $1.2B valuation. Earlier roles include driving React migrations at uberall and inventing an early “write once, run anywhere” framework and no-code lesson builder at Qooco, showing a long history of pragmatic platform-building. Today he focuses on ultra-low-latency MEV searcher development on Solana, writing on- and off-chain Rust engines, operating bare-metal validators, and prototyping high-frequency strategies with sub-millisecond constraints. He combines deep front-end architecture and people leadership with low-level systems and trading-engine expertise—a rare cross-section that helps translate product needs into performant, auditable infrastructure. Colleagues can expect a leader who still ships code daily and tackles both strategic scaling and very small latency wins.
