React & Firebase Developer Needed for AI App (Bug Fixes & Maintenance)

Job ID: 39193632

Budget: $30 – $250 USD

Project Overview

I’m looking for a skilled React & Firebase developer to fix existing bugs, improve stability, and provide ongoing maintenance for an AI-powered event reminder app.

The app is fully built using:
✅ React (Vite.js, Tailwind CSS)
✅ Firebase (Authentication, Firestore, Functions, Hosting)
✅ Stripe (Subscription Management)
✅ SendGrid (Email Notifications)
✅ Slack (Integration for Notifications)

The project was developed using AI-assisted tools (Claude 3.7 & Windsurf), and I need someone experienced in debugging AI-generated code and optimizing performance. Task Scope (Fixed-Price: $100)

? Primary Bug Fixes & Stability Improvements:
• Test & document any remaining issues
• Fix UI/UX issues in the subscription flow (payment form display & processing)
• Ensure event reminders function correctly
• Confirm AI-generated messages are working properly
• Fix minor styling & layout inconsistencies
• Optimize Firebase database queries & security rules
• Ensure mobile & cross-browser compatibility

? Codebase: Hosted on GitHub (access will be provided upon hire).
Ongoing Paid Maintenance Role (Post-Launch, Hourly As Needed)

Once the app is live, I will need on-demand maintenance, including:
• Fixing bugs & issues when they arise
• Monitoring Firebase security & database performance
• Making small text/content updates
• Ensuring all integrations (Stripe, SendGrid, Slack) continue working smoothly
• Assisting with Firebase hosting & deployment issues

? This will be a paid, on-demand role—ideal for someone who wants ongoing but low-commitment work.
Ideal Candidate Qualifications

✅ 3+ years of experience with React & Firebase
✅ Experience with Stripe (subscription-based payments)
✅ Strong debugging & problem-solving skills
✅ Comfortable working with AI-generated code (Claude, Copilot, etc.)
✅ Clear & patient communication with a non-technical founder
✅ Reliable availability for occasional maintenance requests

? Bonus Skills:
⭐ Experience maintaining production apps
⭐ Strong Firebase security & performance optimization skills
⭐ SendGrid email system experience
⭐ Background in AI-powered applications

How to Apply

Please include:
? A brief summary of your experience with React & Firebase
? Examples of past projects involving Stripe subscriptions
? How you approach debugging & optimizing Firebase queries
? Your availability for ongoing maintenance support

? Budget: $100 fixed-price for initial fixes (with potential for hourly ongoing work).
Why Work on This?

✅ One-time bug fix task ($100) to finalize stability
✅ Paid, ongoing maintenance role (hourly, as needed)
✅ No unnecessary meetings—just focused work
✅ Work with an already built app, not from scratch
✅ Long-term opportunity for the right candidate

? Looking forward to working with a reliable developer to keep this app running smoothly! ?
