About this Gig
Is your application throwing cryptic errors? Did your last developer leave you with broken code, or did an AI model generate a script that completely crashed your system?
I am here to step in and fix it properly. As a seasoned full-stack engineer, I specialize in dissecting complex codebases, hunting down rogue bugs, and building rock-solid API integrations that don't break under pressure.
What I can handle for you:
- Debugging frontend framework errors (React, Next.js, Vue)
- Fixing backend runtime and server crashes (Node.js, Express, Python, PHP)
- Connecting payment gateways and webhooks (Stripe, PayPal, Paystack)
- Database plumbing and configurations (Supabase, PostgreSQL, MongoDB, Firebase)
- Resolving state management, routing, and deployment issues (Vercel, AWS, Heroku)
Why choose me over generic automated fixes?
AI tools look at code in isolation. I analyze your entire architecture, application logic, and data flow to ensure the fix is permanent and doesn't trigger new errors down the line.

FAQ
What do you need from me to start working on the fix?
I will need a brief description of the issue (screenshots or error logs help immensely) and access to the code repository (GitHub/GitLab) or hosting environment depending on the project scope.
Can you sign an NDA before looking at my codebase?
Absolutely. I respect your intellectual property and privacy. If your company requires a standard Non-Disclosure Agreement before sharing the repository, let me know.
