$5/hr Starting at $25

I’m a Full-Stack Developer experienced in debugging, maintaining, improving, and extending web and mobile applications. I work across frontend, backend, databases, APIs, authentication, integrations, and deployment to identify problems and implement reliable solutions.

My technical stack includes React, Next.js, JavaScript, TypeScript, Node.js, Express.js, Python, PHP, Laravel, Flutter, React Native, Java, Kotlin, MongoDB, PostgreSQL, Firebase, Supabase, Docker, Git, and GitHub.

I can handle:

• Frontend bugs and UI issues
• Backend and API errors
• React, Next.js and Node.js issues
• Flutter and React Native bugs
• Database errors and query problems
• Authentication and authorization issues
• Third-party API integrations
• Firebase and cloud-service issues
• Payment integration problems
• Performance optimization
• New feature implementation
• Existing application maintenance
• Deployment and production issues

My process is focused on understanding the existing codebase, identifying the root cause, implementing the appropriate fix, testing the result, and keeping the existing functionality stable.

I prioritize clean, maintainable code, careful debugging, clear communication, and practical solutions that fit the existing architecture.
