About this gig
Your app is broken and every hour it stays broken costs you money.
Maybe it's a crash your users keep hitting. A payment flow that silently fails. Login that works on desktop but not mobile. A last developer who said "fixed" and it wasn't. Or AI-generated code falling apart in production.
Whatever it is, it's fixable. I trace the root cause, fix it properly, and explain what went wrong so it doesn't come back.
- Frontend crashing, state broken, pages won't render React, Next.js, Vue
- Backend errors, APIs timing out, logic breaking Node.js, Python, PHP, Elixir (Phoenix/LiveView)
- Queries crawling, connections dropping PostgreSQL, MongoDB, MySQL, Oracle
- Containers failing, microservices down, deploys breaking what worked yesterday
- Legacy codebase mid-migration and everything's breaking in between? That's exactly the mess I sort out.
I don't need you to be technical. "It's broken and here's what I see" is enough to start.
Send me the bug. I'll tell you what's wrong before you spend a dollar.
