Hello, your "Full-Stack/Backend Developer - API Optimization, React Native Subscriptions & Automation" project is right in my wheelhouse. I develop modern JavaScript apps end to end — React/Vue/Next on the front and Node/Express on the back, in TypeScript where it helps. Working with javascript, python, google app engine, opencv, react native, automation, api development, api integration, fastapi, vibe coding, I focus on responsive, fast UIs, clean component structure, and reliable APIs — no page-builder shortcuts. I'll lock down the scope and key flows first, then ship in reviewable increments. Let's hop on a quick chat to align on your requirements? ⭐ 5.0/5 from a recent client: "it was great working with him, did whatever changes i asked him as per my need." Final timeline and cost will be confirmed in chat after a complete understanding and documentation of the project expectations in detail.

With your project's complex demands, I'm the right developer to tackle it head-on. I've mastered Python and FastAPI, developing APIs and optimizing them for peak performance. In addition, I have a wealth of experience integrating third-party REST APIs like the JSON search API you require. I guarantee that data extraction from creator profiles will remain swift while my vast exposure to computer vision, OpenCV inclusive, is another edge I bring to bolster your project. On the frontend, implementing an In-App Subscription/Paywall system with React Native is well within my abilities. My track record includes flawlessly establishing such systems on different platforms including App Store and Google Play. And as a full-stack developer with JavaScript expertise

Hi, This is Jagrati. I’ve gone through your project description and understand that you need an experienced full-stack developer to optimize your FastAPI backend, add a subscription system in React Native, and build an automated video rendering and social media distribution pipeline. With experience in Python, FastAPI, REST API integrations, React Native, mobile subscriptions, automation workflows, and performance optimization, I focus on building efficient and scalable solutions. I can help remove unnecessary dependencies, improve backend performance, integrate external APIs, maintain OpenCV processing logic, implement caching and error handling, add RevenueCat-based subscriptions, and build automated FFmpeg/GitHub Actions workflows. I’m comfortable using AI-assisted development tools such as Cursor, GitHub Copilot, and Claude to accelerate delivery while maintaining clean, documented, and production-ready code. I’ll approach each milestone carefully with testing, reliability, and future scalability in mind. Before we get started, I’d like to clarify a few details: Q1 – Is the React Native app already published on both App Store and Google Play? Q2 – Which database and cloud infrastructure are currently used for the backend? Q3 – Do you already have the social media automation accounts/APIs configured? Looking forward to discussing your project!

Hi there, I can refactor your FastAPI backend by replacing Playwright with the JSON Search API while preserving OpenCV logic, caching, fallbacks, and creator-profile extraction. I can also implement RevenueCat subscriptions in React Native and automate FFmpeg rendering, social posting, and Firebase notifications. Is the current backend and mobile codebase documented and ready for review? Thanks Srdan

I noticed you want Playwright removed to cut RAM and CPU while moving to a premium JSON Search API and creator profile extraction, which is where performance gains matter. I help teams build scalable backends and polished mobile experiences that unlock new revenue streams. I deliver clean, seamless integrations across FastAPI, React Native subscriptions, OpenCV and automation pipelines, we have 75+ 5-star reviews on similar projects and rank in the top 1% among 75 million users! What is your desired timeline for the three milestones, and do you already have RevenueCat and the JSON Search API access ready? Regards, Hamza

@arakir2eee

Hi. I understand you need a developer who can improve your existing Python/FastAPI backend, add a subscription-based premium experience in your React Native app, and build an automated content distribution pipeline. The main goal is to reduce backend resource usage, improve search performance and reliability, monetize the app through subscriptions, and automate video/social workflows to support growth. I’m fully capable of handling this project. I have experience with Python, FastAPI, React Native, REST API integrations, automation workflows, OpenCV-based processing, and performance optimization. I can refactor the backend to remove Playwright overhead, integrate the new search API, preserve your existing extraction logic, and implement caching/error handling for a stable system. I can also handle the React Native subscription flow with RevenueCat, including paywall UI, premium access control, and subscription management, along with building the FFmpeg/GitHub Actions video pipeline and automation workflows for social platforms and Firebase notifications. I’d like to discuss your current backend architecture, mobile app setup, and the expected subscription flow so I can understand the existing codebase and provide the best implementation plan for these milestones. Looking forward to discussing your project.
