About me
I build web apps and automations for small businesses — the kind that take the daily routine off the owner's hands.
Usually: websites and landing pages, intake forms with a client database behind them, booking and group management, payment tracking, automatic reminders and notifications, admin panels, Telegram bots.
Tech: Next.js, React and TypeScript on the web side, Python for automation, PostgreSQL for data, deployed on Vercel and Render.
I start from what actually eats your time, not from a list of technologies. Before we begin you get the scope and a day-by-day plan in writing: what gets built, what deliberately doesn't, and by when. After launch — two weeks of free fixes, daily backups and uptime monitoring.
I work in English, Polish and Ukrainian.
