About me

Full-stack developer focused on automation and AI integration. I build Telegram and Discord bots, web apps (Next.js / React / Node.js), Python backends (FastAPI), web scrapers and data pipelines, and AI-powered tools using OpenAI and Claude. Strong crypto / Web3 background: real-time market-data pipelines for Binance and Bybit, trading and options analytics (including a published Rust library), and automated crypto content systems. I work fast and deliver clean, tested, working solutions, and own tasks end to end - from spec to deployment. Available for short- and long-term remote work. Payments in USDT/crypto welcome.

Work experience & achievements

Automation for marketplace sellers and small businesses. I build Google Sheets and Apps Script tools that pull data from marketplace APIs, assemble reports and manage advertising bids; Python scrapers and data pipelines; Telegram bots for orders, alerts and FAQ. Two of my systems run in production for an Ozon seller right now, on a 15-minute cycle: one plans supplies and builds analytics, the other manages ad bids against a target cost-of-sale. Both keep retries, error logs and a record of every change - a script that fails silently is worse than no script.
