You will get API Integration with Ruby on Rails or Node.js
Project details
You will get a reliable and well-structured API integration developed with Ruby on Rails or Node.js.
I have experience building and maintaining API integrations for real-world applications, including authentication, data synchronization, webhook handling, and error management. I focus on writing clean, maintainable code that is easy to understand and extend in the future.
Whether you need to connect your system to third-party services, consume external APIs, or expose your own endpoints, I can deliver a solid integration tailored to your needs, along with proper documentation.

Node + React Developer for Brazilian Correio's API Integration
Raphael was an excellent developer to work with. He delivered a complete integration between our system and the Brazilian Correios API using Node.js and React.
He successfully implemented automated PDF label generation, built a clean and intuitive user interface, and made sure everything worked reliably with our database.
Raphael is professional, communicative, proactive with suggestions, and delivered everything on time. The quality of the code and the final result exceeded my expectations.
I highly recommend Raphael for any full-stack or API integration projects. Would definitely work with him again.

About Raphael
Senior Full-Stack Developer | Rails + React + Node + React Native
Juiz de Fora, Brazil - 4:13 am local time
I help clients deliver reliable, maintainable, and high-performing solutions. Here are some concrete results I’ve achieved:
• Reduced critical uploader and integration failures from dozens per day to less than 5 per week by implementing better logging, error handling, and reliability strategies.
• Increased automated test coverage from ~50% to 95% while refactoring legacy Ruby on Rails codebases, significantly improving long-term maintainability.
• Built responsive React dashboards and admin panels with dynamic filtering, real-time data visualization, and clean UI/UX following mobile-first principles.
I have strong experience with API integrations (REST and GraphQL), backend development with Sidekiq and PostgreSQL, and frontend architecture using TypeScript, Redux, and Tailwind. I’m comfortable working across the full stack — from database and backend logic to polished user interfaces.
I’ve worked remotely with international clients for several years and am used to clear communication in agile environments. I operate through a Brazilian company and am fully set up for international contracts.
Whether you need a new feature, a full module, legacy code refactoring, API integrations, or a complete web application, I can deliver clean, well-tested code and take ownership of the solution.
I’m currently available for new projects. Feel free to invite me to your job posting or send me a message here on Upwork so we can discuss how I can help.
