Whether you need a pixel-perfect landing page hand-coded from a Figma file, a React/Next.js app wired to live APIs, or a Python automation/bot running on your own server, I build it properly: clean code, modular structure, and easy to maintain. I don't rely on page-builders or bloated templates. Everything I deliver is hand-written, well-organised, and documented — so you (or your next developer) can extend it without untangling a mess. What I can build for you: 🎨 Frontend — Semantic HTML5, modern CSS (Flexbox/Grid), pixel-perfect responsive design, React, Next.js, Angular ⚙️ Backend & APIs — Node.js, Express, Python (FastAPI), REST APIs, authentication, integrations 🗄️ Databases — MongoDB, PostgreSQL, Supabase, Redis (clean CRUD + secure connections) 🤖 Automation & Bots — Telegram/Discord bots, scrapers, workflow automations 🚀 DevOps — Docker, CI/CD, deployment to your server or cloud, with setup docs ⛓️ Specialty: Blockchain / Web3 — smart contracts, dApps, and tokenization (a bonus if your project needs it) How I work: ✅ I take time to understand your requirement first — no guesswork ✅ Clean, commented, modular code + a clear README so you can run it yourself ✅ Testing proof (screenshots/screencast) so you see it working before we close ✅ Quick, clear communication and fast turnaround ✅ Responsive to feedback throughout the build I'm building my reputation here on Upwork, which means you get a developer who is genuinely invested in delivering quality and earning a great review. If you have a project in mind, send me a message — happy to discuss the details and get started. Let's build something clean and reliable together. 🚀 less
