I will do bubble bugfix, workflow optimization, and API integration fix bubble issues
David Lum
About this gig
Your Bubble.io app is live and something just broke
Maybe workflows suddenly stopped working, an API integration is failing, or users are stuck in loading states with no clear reason. When a Bubble app is already in production, guessing is risky.
I specialize in Bubble bugfix, workflow optimization,& API integration troubleshooting for live Bubble.io apps. If you need a focused Bubble app audit backend debugging or performance optimization you're in the right place.
Why I do this
Most Bubble developers enjoy building new features.
Very few are willing to step into an existing app, untangle complex logic, debug broken workflows, & trace API failures without breaking production.
I focus on root-cause debugging, clean architecture & making Bubble apps stable predictable, & maintainable again.
What I do
- Fix Bubble bugs, broken conditions, race conditions, & backend loops
- Debug API integrations, API Connector issues, webhooks, & failed responses
- Optimize Bubble workflows for performance and reliability
- Audit database queries, privacy rules, and data access logic
I work directly in live Bubble apps without breaking production.

FAQ
Will fixing bugs break my live Bubble app?
No. I work carefully inside live Bubble apps, apply fixes safely, and test changes properly to avoid disrupting active users or production data.
how will I know what was fixed?
You’ll receive clear, simple explanations of what was broken, why it happened, and what was done to fix it no technical jargon required.
My app only breaks for some users , can you still fix it?
Yes. These issues usually come from privacy rules, workflow conditions, or race conditions, and I specialize in identifying and fixing them.
What if the issue is caused by an API integration?
That’s exactly what I handle. I debug Bubble API integrations, API Connector setups, webhooks, and failed responses to find the real root cause.
What if my app was built by another developer or AI?
That’s very common. I regularly audit and optimize existing Bubble apps, even when the original developer is unavailable or the logic is messy.
