Pavel Lesyuk

I architect end-to-end testing and security ecosystems that let small teams ship safely at massive scale. From core SDKs to high-scale Telegram ecosystems and consumer apps, I build deterministic quality frameworks that keep critical layers bulletproof. I specialize in zero-to-one execution — taking products from a 6-person startup to millions of users — while driving performance tuning (50k+ RPS) and Agentic QA with a strict DevSecOps mindset.
