At TrendArena, I owned the architecture and backend for a mobile-first Telegram Mini App trading platform that reached ~25,000 testnet users. I designed an Event Sourcing architecture to keep a replayable audit trail of game state, token trades, and lootbox transactions.
I also built secure server-side game mechanics and the React and TypeScript frontend, and developed and audited Solidity contracts and Web3 integrations for meme-token trading. I defined the Mini App infrastructure and blockchain integration architecture and set up DevOps processes for the testnet launch.
At Poem LLC, I led teams of 10–12 engineers and worked on products including Transportica and a custom centralized-exchange trading engine. I designed the trading core’s microservice architecture and implemented a Node.js matching engine with Tarantool, while also building Node.js backends with C++ native addons and optimizing PostgreSQL for high load.
