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 ([login to view URL], 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! ?

Dear Client, As a freelancer with 7+ years of experience in full-stack development, I've not only honed my skills in technologies such as React and Firebase that your project relies on, but I've also had extensive involvement with various AI-powered applications. This makes me uniquely equipped to take on the challenge that comes with debugging and optimizing AI-generated code, similar to the one you're tackling. Another aspect that sets me apart is my familiarity with Stripe's subscription management - a crucial component of your application. Having previously integrated Stripe into many projects, I'll be able to navigate through any payment-related errors or inconsistencies seamlessly. Moreover, your mention of "ongoing paid maintenance" resonates well with me as I thrive on continuing support, fixing bugs promptly, ensuring integrations work smoothly, and making timely updates. Furthermore, I maintain a clear line of communication which will ensure a smooth workflow minimizing disruption to you as a non-technical founder. With all said and done, however, what truly ignites my passion for taking up this project is the chance to work on an already built application to improve its stability rather than starting from scratch – it's like shining a functional gem! Let's collaborate and maximize the potential of your AI-powered event reminder app!!! Thank you!!!

With over seven years of experience in full-stack development, I bring a versatile skill set to the table that is perfectly tailored for your project needs. My primary framework, React.js, aligns seamlessly with your demands as does my knowledge of Stripe subscription management, as previously mentioned. That being said, my aptitude for troubleshooting is one of my standout qualities - I’ve spent a considerable amount of time identifying and fixing bugs throughout my career. I'm confident this could be an asset in highlighting and resolving any remaining issues your app might possess. Equally important, I'm no stranger to not only working with Firebase but optimizing its performance as well. Given the complexity of an AI-powered app like yours, the proficiency in enhancing security rules and database queries could prove extremely helpful in boosting not just your app's performance but its overall security too, Firebase hosting will be second nature to me too. At the heart of it all, however, is understanding your unique requirements and providing you with peace-of-mind service, which prominently features clear and patient communication. As a non-technical founder myself, I grasped the importance of this early on and implemented it extensively throughout my career. So let's not let these bugs get you down; I'm here to lend a solution-oriented hand to ensure that your app remains stable today and every day after its launch.
