Need a reliable developer who can build your web platform, backend, or mobile app — and take it all the way to production? I develop full-stack web and mobile applications using React, Next.js, React Native, Expo, TypeScript, Node.js, and NestJS.

I can help you with: • Building full-stack web applications from scratch • Developing React and Next.js frontends • Creating iOS and Android apps with React Native and Expo • Preparing and publishing mobile apps to the App Store and Google Play • Building backend services and REST APIs with NestJS, Express, or Fastify • Implementing authentication, databases, payments, and third-party integrations • Fixing bugs and extending existing web or mobile applications • Improving performance, code quality, and maintainability • Converting designs into responsive, production-ready interfaces Core technologies: Frontend: React, Next.js, TypeScript, JavaScript, Tailwind CSS, HTML, CSS/SCSS Mobile: React Native, Expo, iOS, Android, App Store and Google Play publishing Backend: Node.js, NestJS, Express, Fastify, REST APIs Data & infrastructure: MongoDB, Supabase, Neon, Appwrite, Docker, Git I write clean, structured code and communicate clearly throughout the project. I can independently deliver a complete product or join an existing team to develop specific features. Tell me about your product, current stack, and the result you want to achieve. I’ll help you determine the best way to build or improve it.
