FullStack Developer for Telegram Bots, Mini Apps and Dashboards
Ucraina
Ucraino, Russo, Inglese
Chi sono
I build full-stack web apps, SaaS MVPs, dashboards, Telegram bots and Mini Apps for real business workflows.
I can help with frontend, backend APIs, databases, admin panels, forms, CRM-style tools, automation, integrations, and deployment-ready project structure.
My background in Computer Science and programming teaching helps me communicate clearly, explain technical decisions in simple words, and keep projects organized.
I focus on clean UI, reliable structure, practical features, and business-ready solutions instead of just writing code.
