Need a working MVP, mobile app fix, Telegram bot, or React/Next.js deployment fast? I build small and medium products end-to-end: clean UI, backend/API, payments, admin panels, deployment, and production debugging. I am a product-minded full-stack and mobile developer. I am strongest when the goal is not just to write code, but to turn an idea into a usable demo, MVP, or internal tool that a client can test, show, sell, or launch. What I can help with: - React / Next.js / TypeScript web apps, landing pages, dashboards - React Native / Expo apps for iOS, Android, and web - Telegram bots and mini apps - Python / FastAPI APIs, admin panels, and automation - Supabase / Firebase / PostgreSQL / SQLite - Stripe Checkout, subscriptions, webhooks, and payment flows - Vercel / Netlify / VPS deployment, environment setup, and debugging - API integrations, webhooks, Google Sheets, maps, charts, and data visualization Recent project experience: - React Native + Expo mobile/web app with live data, maps, widgets, analytics, TestFlight/App Store/Android builds - Telegram subscription bot with admin panel, payments, referrals, promo codes, server metrics, and Linux deployment - FastAPI data platform with external APIs, public/admin endpoints, tokens, charts, production deployment, and incident debugging - TV/admin dashboard with live weather/water data, media management, responsive layout, cache fixes, and production release work I prefer clear, scoped projects: MVPs, prototypes, bug fixes, deployments, payment/API integrations, and product improvements. I am new on Upwork, so I am happy to start with a small paid milestone or a fast prototype and prove the quality quickly.
