I will fix bugs and feature development to web apps


Level 1
About this gig
Your software already works. Let's make it work better.
If you have an existing web application that needs bugs fixed, features added, APIs connected, or existing functionality improved, I can continue the development without treating the project like a new build.
I work with existing applications, including business software, CRM and ERP systems, dashboards, portals, ecommerce applications, and SaaS products.
I can help with:
- Bug fixes and error investigation
- New features and modules
- API integrations
- Database issues
- Performance improvements
- UI and functional fixes
- Authentication and permissions
- Existing CRM, ERP and business software
- Refactoring and code improvements
- Ongoing developmen
I first understand the existing application and the change you need, then scope the work before development.
If you have an existing application and know what needs to change, send me the details, screenshots, error messages, or repository information.
