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.

I have over 10 years of experience in Unity. I have developed 20 games so far ranging from turn based to online strategy with match making. I am experienced with Unity's event flow and have a firm grasp of the Structures and Idioms needed in Game Development. My expertise lies in multiplayer games with simple rules that yield complex interactions between users. It doesn't take me long to have a working prototype and my projects are mostly designed to work with mobile and various account systems like Steam, IOS and Google-Play. My recent project is a game called Chess Cubed which will be out on Steam and Android and IOS soon. The game was completed in 6 weeks and offers innovative game-play. This is blazing fast compared to other 3D chess variants that typically estimate 6-8 months of development time and leaves a lot more room for visual polish and Q&A. What more can I say?
