AI Chatbot Developer | Next.js | React Node.js | Nextjs Full Stack

I am a Senior Next.js Developer focused on React, Node.js, and API-driven web applications. My main work is building custom web products where the frontend depends on clean architecture, reliable API integration, authentication, and real user workflows. I usually work on Next.js / React applications connected to existing backends, Node.js services, REST or GraphQL APIs, Firebase, CMS tools, and third-party integrations. I can help when you need a React developer or front-end developer who can do more than just build UI screens. I can take Figma designs, Bootstrap themes, existing prototypes, or legacy interfaces and turn them into production-ready Next.js / React pages connected to real data and backend logic. I also support full-stack Next.js and MERN-stack products when the project uses React, Node.js, Express.js, MongoDB, or a similar JavaScript-based stack. My backend work usually covers API integration, authentication flows, account logic, dashboards, ecommerce flows, admin panels, and integration with external services. Earlier in my career, I worked with WordPress, CMS-based websites, and classic web development projects. That experience helped me understand content structure, SEO-friendly pages, admin workflows, landing pages, and business websites. Today, my focus is custom development: Next.js applications, React frontends, full-stack Next.js products, SaaS platforms, ecommerce flows, marketplaces, customer portals, and web applications built around real product logic. Typical projects I can help with: - Next.js and React web application development - full-stack Next.js development with Node.js and Express.js - React developer / front-end developer work for existing products - REST API and GraphQL API integration - Firebase, Firestore, and Google Cloud Platform integrations - NextAuth and custom authentication flows - SaaS dashboards, customer portals, marketplaces, and ecommerce platforms - Strapi, headless CMS, and CMS-driven web products - Figma-to-Next.js or Bootstrap-to-Next.js implementation - frontend architecture, performance improvements, and code maintainability Tech I work with: Next.js, React, TypeScript, JavaScript, Node.js, Express.js, NestJS, MongoDB, PostgreSQL, RESTful API, GraphQL, Firebase, Firestore, Google Cloud Platform, NextAuth, Redux, Strapi, CMS integrations. I am comfortable joining an existing team, working directly with a CTO or founder, taking ownership of a product area, and moving features from backlog to release.
