Greetings, I understand you need a developer to complete and polish an existing full-stack app built with FastAPI and React, including Stripe payments, plan management, search improvements, product image fixes, UI enhancements, and a simple landing page, all within a fixed $200 budget and 7–10 day timeline. Before we proceed, could you clarify, 1, Are the Stripe products and plans already partially configured, or do they need full setup from scratch? 2, For the search improvements, are there specific sources or APIs you want included? 3, Any preferred layout adjustments for the UI beyond color scheme updates (Dark blue, black, white)? Our team has hands-on experience with FastAPI, React, and Stripe integration. We focus on completing existing builds efficiently, improving reliability, and ensuring seamless frontend-backend integration. We can deliver within your fixed budget and timeline, including onboarding workflow fixes and quality checks. Regards Yasir LEADconcept PS: I can share examples of similar full-stack projects where we implemented Stripe payments and improved search and UI functionality.

@asifalimzd

Hi there, I’ve reviewed your project requirements and it’s clear you need a developer who can finalize and polish an existing FastAPI + React application rather than starting from scratch. The tasks around Stripe integration, improving search reliability, fixing product image loading, and enhancing the UI/UX with a modern color scheme are all well-defined. I can ensure these features are completed within your fixed budget and timeline, while also making sure the frontend and backend work seamlessly together. To better align with your expectations, could you confirm whether the current onboarding workflow is fully functional or still requires integration with the payment and plan logic? This will help determine the scope of adjustments needed. Kindly send me message to discuss more in detail. Thanks

@Microlent

Yes to all three. I’ve used Stripe for subscriptions and plan-based access, and I’ve worked with FastAPI + React (Vite) on existing codebases.

I can: • Add Stripe payments and plan logic (Free/Paid) • Fix search reliability and image loading issues • Improve UI (dark blue / black / white theme) • Add a clear landing page and complete onboarding • Do full frontend–backend checks and bug fixes I focus on shipping, not experimenting, and can deliver within 7–10 days. Happy to take this forward and continue if it goes well. Best regards, Jenifer

@developper69

Hi there, I’ve reviewed your FastAPI + React app and I’m confident I can finish the remaining features within your 7–10 day window. I have hands-on experience delivering Stripe-powered payments, plan tiers, and reliable user-plan enforcement in similar stacks, plus solid work refining UI and onboarding flows. Here’s how I’ll approach: - Payments & Plans: integrate Stripe (Checkout/Payment Intents), define Free/Paid plans, ensure plan state syncs with backend and frontend. - Search Results: broaden sources, improve relevance/ranking, add debouncing and error handling to boost reliability. - Product Images: fix image loading in search results and ensure fallbacks. - UI Improvements: update to a dark blue/black/white palette, modern layout, consistent spacing, responsive. - Landing Page: simple, clear explanation and CTAs to sign up or choose a plan. - General Checks: run regression tests, fix broken pieces, verify frontend-backend integration, ensure onboarding works. - Onboarding workflow: ensure a smooth signup to trial/paid path. I will begin with Stripe integration and core plan enforcement, then proceed through the tasks in a logical sequence. I can deliver a working Stripe-enabled milestone within 2–3 days and complete the rest by day 7–10. Best regards, Muhammad

@AbhishekSingh08

Hello there! My name is Abhishek. I am a seasoned Full-Stack Developer with extensive experience in both frontend and backend technologies. Fortunately, I tick all the boxes you need for this project. I have proficiency with both FastAPI and React, having contributed to numerous successful projects involving them. Moreover, my past experience with Stripe aligns perfectly with your requirement of integrating payment systems and different app plans. So, fears of inconsistency and hours wasted on learning curves will be non-existent. Continuing an existing project requires a special set of skills – flexibility and adaptability being two of them. Over the years, I've developed a knack for seamlessly working with existing codebases, debugging efficiently and applying logical changes without impacting functionalities. I might be the missing piece that both your backend and frontend have been looking for; someone who can ensure they operate in perfect harmony and fix existing features that could use some improvement.
