I'm currently working on Carpool, an urban carpooling app, using React Native, Python (FastAPI), NestJS, MongoDB and PostgreSQL. I set up the infrastructure on AWS with ECS, EC2, Load Balancers, API Gateway and automated pipelines (CodePipeline, CodeDeploy, CodeBuild and GitHub Actions).I developed a payment system responsible for processing transactions and passing them on to drivers, implementing an asynchronous service with Amazon SQS for pub/sub communication.

I developed the app for the Parceiro da Construção platform, which offers free online courses for construction professionals. I used React Native, Redux, Expo and TypeScript to create a smooth and intuitive experience for users. As well as taking care of publishing and managing the app in the stores, I was also responsible for keeping the app running smoothly, prioritizing bug fixes and improvements to the structure. To manage the project, we adopted the agile Scrum methodology, using the Jira tool to track progress. I also redesigned the way the courses were displayed, better organizing the data and improving the application's efficiency. The result was a more stable application with fewer problems and a more satisfactory user experience.

I was responsible for developing Instavagas, an innovative platform that connects on-demand professionals with hospitality companies. I developed two applications: one for companies to manage vacancies and processes, and another for freelancers to apply for jobs and communicate via chat. I set up the cloud environment, CI&CD, and used technologies such as React Native, Redux, Expo and TypeScript for the applications. I published and managed the apps in the stores, as well as creating a robust backend with NestJS, Postgres and Prisma, and implementing caching with Redis. I solved latency problems by optimizing API responses with Redis, improving the speed of operations. I developed a real-time chat with Socket.io, facilitating instant communication between companies and freelancers. I used AWS services (EC2, RDS, Load Balancer) to ensure the platform's scalability and reliability. I created an asynchronous notification microservice using RabbitMQ, ensuring that messages were delivered efficiently. In addition, I built an administrative dashboard with Next.js, enabling efficient management of vacancies, companies and applications. My work resulted in a faster, more efficient and scalable platform, providing an improved user experience and facilitating the connection between freelancers and hospitality companies.

Jinboo is an innovative tourism and entertainment social network from the Kontik group (FCM TRAVEL), where users can share travel experiences and buy tickets, book hotels and packages directly through the app, integrated with Zupper Viagens (another Kontik group company). I worked on creating the app using React Native, Redux, Expo and TypeScript, including a Stories feature similar to Instagram, which increased user engagement. I used Scrum agile methodology with Jira to make our team more efficient and collaborated with the QA team to solve critical bugs, ensuring a stable user experience. On the backend, I solved problems using Node.js, TypeScript, NestJS and Neo4j, and improved system performance by optimizing graph queries. I also developed and optimized the search for tickets, hotels and packages, integrating it with the Zupper API, which made searches faster and more accurate.

Botev was a company that some friends and I created with the aim of helping entrepreneurs get their ideas off the ground through technological solutions. Our aim was to turn ideas into reality by providing tools and platforms that would make life easier for users.Projects:- HealthChecker: I developed prescription and formula software with a powerful search tool. This tool allows instant access to an extensive library of medical prescriptions, ranging from common formulas to more complex clinical cases, helping doctors and health professionals to manage and consult prescriptions.- Repassafone: I developed the Repassafone platform, a company that buys and sells used cell phones. Repassafone aims to offer quality cell phones at an affordable price. The platform allows users to buy and sell cell phones safely and reliably, guaranteeing the circulation of overhauled products in good condition.- Kultivi: I took part in the development of the Kultivi app, a platform that offers a wide range of free online courses with certificates. Kultivi allows users to learn at their own pace and from the comfort of their own homes.I also created landing pages for small agencies, freelancers and micro-entrepreneurs.Technologies used: NextJS, React, React Native, TypeScript, Heroku, Vercel, PostgreSQL and php
