Senior MERN Developer | SaaS & AI-Driven Solutions

Your next developer isn't just writing code and they're thinking about your product, your users, and your growth. That's the kind of developer I am. 5+ years building web and mobile applications that look sharp, run fast, and scale without drama. I obsess over the details including clean UI, optimized performance, solid architecture because that's what separates good products from great ones. I work with modern AI coding tools (Cursor AI, GitHub Copilot, Vercel v0) to ship faster and smarter. More output, same quality bar. Better, actually. 🛠 TECH STACK: Frontend: React.js · Next.js · React Native · TypeScript · Tailwind CSS · Redux (Thunk, Saga) · Styled Components · GraphQL · Chart.js · Semantic UI · Bootstrap · HTML5 · CSS3 · SASS · Webpack · ES6 Backend & Databases: Node.js · Express.js · Firebase · MongoDB · MySQL · PostgreSQL Cloud & DevOps: AWS · Heroku · GitHub Actions AI Dev Tools: Cursor AI · GitHub Copilot · Vercel v0 📦 WHAT I DELIVER: ✅ Full-Stack Web Apps - fast, responsive, production-ready ✅ Cross-Platform Mobile Apps - React Native for iOS & Android ✅ Progressive Web Apps (PWAs) - offline-capable, mobile-first ✅ Custom Dashboards & Data Visualizations - Chart.js, real-time data ✅ Scalable APIs - REST, GraphQL, third-party integrations ✅ Cloud Deployments - AWS, Heroku, CI/CD pipelines 🏭 INDUSTRIES I'VE BUILT FOR Enterprise & Business Automation · E-Commerce & Marketplaces E-Learning & EdTech · Healthcare · CRM & Productivity Social Platforms · Content & Document Management · Web Portals 💡 HOW I'M DIFFERENT ⚡ I sweat the small stuff including UI details, load times, edge cases 🎯 I align with your goals, not just your ticket list 🤖 AI-assisted workflow means faster turnaround, not lower standards 📱 Web and mobile covered under one roof 🔄 Flexible, communicative, and genuinely invested in your success Good products don't happen by accident.
