At Traffic Experts, I was the sole owner of a Telegram Mini App line with 20,000+ MAU, taking it from architecture to releases. I designed its sports data-provider layer with Redis and PostgreSQL caching, request coalescing, and graceful degradation.
I built an event-driven backend for live data and subscriptions, with event deduplication and multilingual delivery. I also automated content generation and rewriting under editorial rules, including geo-dependent delivery.
For product mechanics, I worked on tournaments and leaderboards, with attribution through Keitaro/S2S postbacks and analytics in PostHog.
On my Telegram Audience Platform project, I developed a multi-tenant SaaS for collecting audiences and running invite campaigns. I also served as the sole frontend developer on a white-label casino Telegram Mini App, rebuilding its UI from Figma.
