I’m a performance-marketing and traffic architect with 10+ years launching and scaling paid-acquisition campaigns, and I go beyond buying—architecting and coding the full stack behind them. I combine media buying, traffic, ad-network operations, and funnel/conversion/ROI optimization across push, native, pop, Telegram Ads, and search (Yandex Direct, Google).

I’m the Founder and Lead Engineer of PromtPress, a Telegram advertising network built end-to-end—from marketing strategy and system design to production code. I integrated 8+ ad networks with automated spend-sync, built a budget-pacing engine and CPF billing, and shipped AI-driven automation using DeepSeek/OpenAI.

My work blends marketing analytics with engineering discipline: tracking/postbacks, anti-fraud controls, web analytics, and conversion testing paired with Python/FastAPI, PostgreSQL, Redis, Vue 3, Docker, and DevOps. I’m motivated by the one-person approach where campaigns launch fast—and the technology directly serves the growth goal.
