Need a fast, reliable web application built with Next.js and Supabase? with testing too?

I help startups, founders, and small businesses build modern, scalable web applications that are easy to maintain and ready to grow. Whether you're launching a new MVP, improving an existing product, or fixing bugs, I focus on delivering clean, high-quality solutions that meet your business goals.

As a Next.js & Supabase Developer, I build responsive and performant applications using Next.js, React, TypeScript, Supabase, PostgreSQL, Tailwind CSS, Node.js, and Express. I also provide Playwright end-to-end testing, manual QA, and API testing to ensure your application works reliably before it reaches your users.
What I can help you with:
• Build MVPs and SaaS web applications
• Develop responsive user interfaces with Next.js and React
• Integrate Supabase Authentication and PostgreSQL databases
• Build REST APIs and backend features
• Fix bugs, improve performance, and refactor existing code
• Write Playwright end-to-end tests
• Perform manual QA and API testing
• Deploy applications and provide ongoing support

I've worked on projects including event management platforms, marketplace applications, school management systems, and other full-stack web applications. These projects have strengthened my experience with authentication, CRUD operations, dashboards, payment workflows, database design, and testing.
I believe successful projects require more than writing code. I communicate clearly, pay attention to detail, write maintainable code, and test my work carefully so you receive a reliable product.
If you're looking for a developer who can build your application and help ensure its quality through testing, I'd be happy to discuss your project and see how I can help.
