If you need a reliable full stack developer who delivers clean, scalable solutions on time — you're in the right place. I'm Anuj, a full stack developer with 14+ years of experience building CRMs, SaaS platforms, Shopify stores, mobile apps, and complex web applications for businesses worldwide. Here's what I've actually built for clients: - Migrated a Shopify store with 17,000+ products, 60,000+ orders, and 100,000+ customers without losing a single record. - Built custom CRMs and SaaS platforms with multi-role dashboards, subscriptions, and automation. - Delivered 20+ API integration and webhook projects connecting third-party platforms seamlessly. - Built and launched mobile apps for iOS and Android using Flutter. Integrated OpenAI and AI chatbots into web platforms for automation and smart user experiences. - Developed healthcare platforms with patient portals, scheduling, and secure workflows. - Built advanced WordPress solutions with custom plugins, automation, and complex workflows. I work in PHP, Laravel, Node.js, Symfony, Shopify, WordPress, Flutter, React.js, Angular, REST APIs, Python, Flask, MongoDB, MySQL, OpenAI, Claude, and Cursor so whether you need a new build, an AI-powered feature, or want to improve an existing system, I can jump in quickly and get things moving. I also use Claude and Cursor as part of my daily development workflow so I build faster, write cleaner code, and deliver more in less time. For clients, that means quicker turnarounds without cutting corners. What makes working with me different? I think like a business owner, not just a developer. I ask the right questions upfront, communicate clearly throughout, and deliver code that's built to last not just built to ship. If you have an existing system or a new idea, drop me a message and I'll review it and suggest the best approach before we start. 👉 Let's build something great together.

WordPress and Shopify sites break, slow down, or hit walls that page builders can't fix. That's where I come in. I build and extend WordPress and Shopify stores at the code level custom plugins, theme development, API integrations, and backend logic that off-the-shelf solutions can't handle. On the full stack side, I work in React, Node.js, and Next.js to build web applications that connect cleanly to your CMS or run standalone.
