À propos de ce service
Are you struggling with bugs, errors, or broken features in your application? I specialize in debugging and fixing issues across frontend, backend, and full-stack applications. Whether it's React, Next.js, Node.js, Python, JavaScript, TypeScript, API integrations, database issues, authentication, deployment errors, or any issue, I help.
I fix frontend bugs (React, Vue, Angular, Next.js, component rendering, state management), backend issues (Node.js, Express, Python, Django, Flask, API endpoints, database queries, server errors), full-stack problems (API integration, authentication, authorization, data flow), third-party library conflicts, environment setup errors, build failures, TypeScript errors, performance issues, and mobile crashes.
With 5+ years of experience, I provide fast turnaround, clean scalable code following best practices, and production-ready fixes. I analyze issues, identify root causes, implement maintainable solutions, test thoroughly, and document.
Before ordering, message me with your technology stack, error messages, reproduction steps, and code snippets. I'll assess your situation. Whether it's a minor bug or critical blocker, I'll get your app running

Hasham delivered both items from the original order — fixed the /api/admin/logs 500 error and installed the Sentry SDK cleanly. When his first deploy surfaced a separate pre-existing issue with our production database, he investigated quickly, owned the gap in his local testing approach, and walked me...

Outstanding work was delivered at an amazing pace. Hasham provided me with a clear audit so I knew what to expect. He delivered high quality work super fast and went above and beyond to make sure everything was set up properly and fully functional.

He went above and beyond. After he wrote my code for half of what everyone else was asking. He ended up fixing a ton of other stuff, and when I broke it the next day.... He got on a hour zoom meeting with me and fixed it all while explaining to me in depth how it all worked. I'd hire him as my CTO =)
