Hi, I'm Serhii! I build clean, fast websites (landing pages, business sites), Telegram bots, and Python scripts that automate boring manual work — parsing, data cleanup, Excel processing. I use modern AI-assisted development tools, so I deliver quickly and at a fair price. Clear communication in English or Ukrainian, honest deadlines, and revisions until you're happy with the result. Let's automate something!
