Good to see this project, I will integrate the third-party APIs into your Node.js/Express backend, connect them to the mobile app, and handle authentication, error handling, and response caching, structured as standalone services with shared middleware. I will add a circuit breaker on each external call, if a service fails, it returns a cached response instead of cascading errors to the app. Questions: 1) Which third-party APIs need integrating? 2) Is the mobile app already built, or is that part of the scope? Send me a message and we can go over the details. Best regards, Kamran

Hi, I’m a Full Stack Developer with 5+ years of experience in MERN/MEAN and mobile app ecosystems (React Native, Flutter, Android, iOS). I specialize in production-grade Node.js integrations and have successfully connected multiple third-party REST APIs to scalable backends and mobile apps. For your project, I can: Integrate external REST APIs into a clean, modular Node.js (Express) architecture Secure endpoints using JWT/OAuth/API keys with proper validation Optimize responses and implement robust error handling & logging Seamlessly connect the backend with your mobile app (React Native/Flutter/native) Implement webhook handling where required Follow a professional Git workflow and write clear integration docs I focus strongly on performance, maintainability, and secure API communication — ensuring your system is production-ready and scalable. Bonus strengths: payment API integrations, API performance tuning, and deployment support (AWS/DigitalOcean). I can start quickly and deliver reliable, well-structured code. Let’s discuss your API providers and current architecture to move forward efficiently. Best, Bharagav

Hi there, I’m Efanntyo, a seasoned full-stack developer and AI specialist with extensive experience delivering production-grade backends and mobile integrations. For your Productivity App project, I will architect a clean, scalable Node.js backend (Express) that securely consumes and integrates third-party REST APIs, exposes robust endpoints for the mobile app (Flutter/React Native/Native), and ensures reliable, high-performance data flows. I will implement solid authentication (JWT, OAuth, and API keys where applicable), comprehensive error handling, and response optimization to keep client apps fast and resilient. What I bring to the table includes: - End-to-end API integration strategy: secure token management, rate limiting, retry policies, and thorough input/output validation. - Clean architecture with modular services, isolation of concerns, and testable interfaces to support future API upgrades. - Mobile app integration readiness: clear API contracts, responsive data shaping, and documented error responses that simplify client-side handling. - Documentation: lightweight, developer-friendly docs detailing setup, authentication, endpoints, and example payloads. My approach will be: 1) Define API contracts and authentication strategy with stakeholders. 2) Implement modular Node.js services for each external API, with centralized error handling and logging. 3) Integrate with the mobile app via stable REST endpoints and consistent data formats. 4) Write concise document

Hi, I’m a Senior Laravel Developer with strong experience stabilizing production systems and resolving complex database and logic-level issues. I’ve worked extensively with Laravel (LTS), PHP 8+, MySQL, queues, API integrations, and Blade/Vue stacks, and I’m comfortable jumping into existing codebases with multiple contributors. For the first milestone, my approach will be: 1️⃣ Reproduce and isolate reported bugs in a staging environment 2️⃣ Audit migrations, relationships, and query logic for data integrity issues 3️⃣ Refactor or patch broken endpoints with clean, maintainable fixes 4️⃣ Add concise regression tests to prevent recurrence 5️⃣ Push structured PRs through your GitHub workflow and validate in CI/CD I also proactively review logs, queue workers, and API integrations for hidden edge cases or performance bottlenecks while resolving core issues. My goal is simple: zero broken endpoints, consistent database behavior, all tests green, and a clear changelog for every fix. Once stability is restored, I’d be happy to stay on retainer for performance tuning, security hardening, and iterative feature development. I can start immediately and prioritize fast, reliable turnaround. Best Regards, Raheel Aslam

@billybryan98

Hello, I hope you are well. I’m an experienced backend developer focused on scalable Node.js architectures and clean API integration. I’ve built production-ready backends that connect multiple REST services to mobile apps, with robust auth (JWT/OAuth), error handling, and performance tuning. I approach this project by outlining a clean, modular backend that can plug third‑party APIs with minimal churn, while maintaining security and observability. In previous roles I’ve wired external REST endpoints into Node.js backends, implemented token management, and delivered well-documented services that teams can extend. I typically use Express or a similar framework, adapt data contracts to JSON/WB messages, and ensure testable, maintainable code with a Git-based workflow. I can handle the work end-to-end, designing the integration, securing communications, and providing a deployment-ready build with brief docs. I’ll deliver a reliable, scalable solution aligned with your mobile integration needs. Best regards, Billy Bryan
