Project description:
"Project Description:
We are seeking an experienced full-stack developer (or mobile app specialist) to diagnose and fix critical issues in our e-commerce/delivery platform. The problems are affecting order processing on the website and automatic driver assignment in the mobile app (used by drivers).
Key Issues to Resolve:

Orders are not processing correctly on the website (e.g., stuck in pending, payment confirmation failures, or inventory not updating properly).
Driver assignment logic in the mobile app is faulty: orders are not being assigned automatically to available drivers, leading to manual intervention and delays.
Related bugs may include real-time updates, notifications, or integration between the web backend and mobile app.

The platform involves a website (likely PHP/Laravel, Node.js, or similar – details provided upon hiring) and native/hybrid mobile apps for iOS and Android (React Native, Flutter, or native – to be confirmed).
Requirements:

Proven experience fixing bugs in e-commerce/order management systems and mobile apps (especially delivery/logistics apps like Uber Eats or similar).
Strong skills in backend (e.g., Node.js, PHP, Python/Django), frontend (React/Vue), databases (MySQL/PostgreSQL), and APIs (REST/GraphQL).
Experience with real-time features (WebSockets, Firebase) and geolocation/driver assignment algorithms is a big plus.
Ability to work with existing codebase (Git access will be provided).
Thorough testing: fix bugs, ensure no regressions, and test on multiple devices/browsers.

Deliverables:

Detailed report of issues found and fixes applied.
Fully functional order processing and driver assignment.
Clean, commented code updates.
Basic documentation of changes.
Post-fix support for any immediate regressions (1-2 weeks).

Timeline:
Urgent – aiming for completion within 2-3 days, depending on complexity.
Budget:

Please include in your bid:

Relevant past projects (links or descriptions of similar bug fixes in order/delivery apps).
Your tech stack expertise.
Estimated time to complete.
Any questions for clarification.

We will provide staging access, detailed error logs, and screenshots/videos of the issues after selecting a freelancer. Looking for someone reliable who communicates well and delivers high-quality work quickly!" (client-provided description)
