Comprehensive Web App Upgrade

@anjna123

Hello, I’d be happy to help overhaul your existing MVP into a more polished, scalable, and user-friendly product. I’m a Full Stack Developer with hands-on experience improving live applications—covering UI/UX redesigns, bug fixing, backend enhancements, admin dashboards, third-party API integrations, and payment gateways. I can modernize your landing page, clean up the UI with reusable components, improve user flows, and ensure the app is stable and responsive across devices. On the backend, I can handle secure API integrations, admin management features, clean endpoint design, and payment gateway setup (including webhooks and status tracking). I focus on clean code, scalability, and clear communication, and I’ll also provide a brief bug-fix report as requested. I’m comfortable working with existing codebases and iterating quickly while keeping quality high. I’d love to discuss your current tech stack, priorities, and timeline. Looking forward to working together. Best regards Anjna
