Chi sono
I build Telegram Mini Apps and bots - and I design them too. One person instead of a separate designer and developer: one price, one point of contact, no handover mess.
Stack: React, TypeScript, Node.js, Python, MongoDB, REST APIs. Design in Figma.
I've built stores with payments, booking systems, subscription tools and admin panels that businesses run inside Telegram every day.
How I work: scope agreed in writing before I start, a live demo link before delivery, replies within 1 hour, and the full source code is yours. No lock-in.
Tell me your idea and I'll say honestly what it takes.
