I will fix react bugs and develop features in your web app
Swayam Mehra
About this gig
Is a broken React screen, failing API integration or unfinished feature slowing down your product? I help startups and teams improve existing web applications without the uncertainty of an open-ended rebuild.
I'm a Full-Stack Software Engineer working with React, Java, Spring Boot, APIs and cloud applications. I can debug frontend issues and follow them through to the API or backend when needed.
Services include broken forms, state and rendering bugs, API integration, loading/error handling, feature development, responsive UI improvements and application troubleshooting.
I work from an agreed ticket or user flow, explain the root cause, deliver source changes and test the expected result. My packages cover one bounded issue, one small feature, or one end-to-end flow.
Please message me before ordering with your repository, screenshots, steps to reproduce and desired result. New designs, major redesigns, new backend systems and large integrations require a custom quote.

FAQ
Can you fix an existing React app?
Yes, if it can be built in a safe development environment and the issue can be reproduced.
Do you also fix the backend?
Small API changes are included only in Premium when agreed. Larger backend changes are quoted separately.
Will you implement my Figma design?
I can work from a supplied design; a substantial design or redesign is separate scope.
What counts as one bug or feature?
One agreed issue or user story with defined acceptance criteria, not unlimited changes.
What will you deliver?
Source code changes, setup/test notes and a concise handover; deployment only if separately agreed.
