Rockstar🎓
Top SchoolIllia Zub is a Director of Engineering with 11 years of experience building high-performance APIs and developer-focused products, currently leading engineering and customer success at SerpApi from Poland. He combines hands-on systems work—improving infrastructure, shipping features, and fixing critical bugs—with people leadership, hiring and mentoring engineers and running SOC 2 Type 1 readiness. Known for performance optimizations (e.g., massive JS decoding and Nokogiri improvements) and shrinking release times and resource usage, he balances deep technical troubleshooting with shipping reliable production services that sustain a 99.995% API success rate. He also drives developer relations and marketing—hosting the SerpApi podcast and presenting publicly—to grow MRR and community trust. Comfortable across full-stack, devops, and web3 tooling, he has a history of reverse-engineering complex systems like Google Maps pagination and solving elusive production issues (Cloudflare-specific ChunkLoadError). His background blends pragmatic engineering, measurable optimizations, and a knack for turning low-level fixes into business impact.
