QA ARCHITECT · HIGH-LOAD

Pavel Lesyuk

Quality infrastructure for high-stakes Web3.

I architect end-to-end testing and security ecosystems that let small teams ship safely at massive scale. From the core TON Connect SDKs to Telegram Superapps with 43M+ MAU, I build deterministic frameworks that keep critical layers bulletproof. I focus on zero-to-one automation, performance tuning (sustaining 50k+ RPS), and Agentic QA — always with a DevSecOps mindset.
