Daniel E
About this gig
Is your software, web app or mobile app not working properly?
Maybe your app is crashing, a page is broken, a button does nothing, data is not saving, an API request is failing, or you are seeing an error you cannot work out.
I can help you investigate the issue, find the cause, and fix the bug properly.
I am a UK-based full-stack developer with 9+ years of experience working on real business applications, including web apps, mobile apps, backend APIs, databases, admin dashboards, internal systems and software integrations.
I can help with:
- Software bugs
- Web app errors
- Mobile app issues
- App crashes
- Broken buttons or pages
- Login problems
- Data not saving
- API connection issues
- Backend logic bugs
- SQL or MySQL issues
- Deployment or hosting errors
- Debugging existing code
What I need from you:
- A short explanation of the issue
- Any screenshots, error messages or logs
- Steps to reproduce the bug
- Code access or relevant files where possible
Please message me before ordering so I can confirm the right package for your issue.
I focus on fixing the actual problem, not just hiding the error.

FAQ
Do I need to message you before ordering?
Yes, please message me first with a short explanation of the issue. This helps me confirm whether it is a small app fix, a medium bug, or a more complex debugging task.
What information do you need from me?
Please send anything that helps explain the issue, such as screenshots, error messages, logs, steps to reproduce the bug, source code access, GitHub/Bitbucket link, or a short video showing the problem.
Can you fix mobile app bugs?
Yes. I can help investigate mobile app bugs, crashes, broken screens, failed API requests, login issues, and data not saving correctly.
Can you fix backend API issues too?
Yes. I can help with API errors, failed requests, backend logic, database issues, authentication problems, and connection issues between the app and backend.
What counts as a small bug?
A small bug is usually one clear issue, such as an error message, broken button, simple app crash, failed form submission, login problem, or one screen not working correctly.
What if the issue is more complex than expected?
If I find that the issue is larger than the package you selected, I will explain what I found before continuing. You can then decide whether to upgrade the order.
Can you work on an existing app or software project?
Yes. I can work with existing codebases, mobile apps, web apps, APIs, databases, admin dashboards, and internal software systems.
Can you fix database-related issues?
Yes. I can help with SQL, MySQL, data not saving, incorrect data loading, connection issues, and backend/database logic problems.
Can you fix deployment or hosting errors?
Yes. I can help investigate deployment, hosting, server, API, environment variable, connection string, and configuration-related issues where possible.
Can you help if I only have screenshots or an error message?
Yes. Send what you have first, and I will let you know whether I need code access, logs, or more details to investigate properly.
