What I'm looking for

I'm looking to lead infrastructure and engineering for high-load platforms where architecture, reliability, launch readiness and infrastructure economics matter. I work best with meaningful technical ownership, direct decision-making and teams that value sound engineering judgement.

I've led infrastructure for Telegram Wallet, carrying wallet and authorization traffic through TON launches including Hamster Kombat, DOGS, Notcoin and USDT-TON. I scaled a fault-tolerant platform running around 40,000 rps, built launch capacity and moved the estate from AWS to dedicated bare metal when the economics demanded it.

As CIO of Waves Group and CTO of Waves Labs and Tidex Exchange, I led organisations of up to 43 people, owned budgets, incident practice and technical direction, and removed about $50,000 a month from AWS spend. Earlier at IPONWEB, I operated real-time bidding ad infrastructure peaking at roughly 6,000,000 requests per second under a 99.95% SLA.

I now build and run a production AI SaaS for legal-document analysis end to end. My work is architecture, technical review and operational judgement: finding the bottlenecks, reliability risks and cost drivers that only emerge under real load.
