I’ll help you maintain and improve your existing web application with a strong focus on reliable debugging, root-cause analysis, and safe feature development. With expertise in Node.js, React, Prisma, MySQL, and API integrations, I can work across the full stack to resolve backend issues, improve existing functionality, enhance the admin dashboard, and implement new features without disrupting the current application. My approach emphasizes clean, well-tested solutions and a clear understanding of the existing codebase before making changes.
