Robust API using MongoDB, Node.js, and Express.js, following clean architecture principles. The API was designed to handle various user roles and their respective permissions while taking into account potential issues that can arise with time zones and enabling seamless communication. Geolocation and distance calculations were also vital parts of the business logic. Implemented dependency injection and dependency inversion to improve the testability and maintenance of the API. By separating the concerns of the application and allowing for easy swapping of dependencies, the code became much more modular and testable. The use of dependency injection allowed me to write more focused and isolated unit tests, which increased confidence in the code's correctness and made it easier to catch potential bugs before deployment. Additionally, the use of dependency inversion enabled me to write integration tests with ease, ensuring that all components of the API worked together seamlessly. By adhering to clean architecture principles and implementing dependency injection and dependency inversion, I was able to create a highly modular and testable API that delivers fast and reliable results.

Designed a robust security system using Arduino sensors, Node.js, MongoDB, and Vue. To provide efficient functionality, I created a REST API that caters to two different clients. Firstly, a back-office application that manages the installation requests for new security systems, maintains the history of sensor movements, and handles the activation or deactivation of sensors. Secondly, a progressive web application (PWA) that empowers customers to monitor their own spaces, allowing them to keep an eye on sensor activity with a detailed view. By utilizing this state-of-the-art technology stack and offering two distinct interfaces, the security system can effectively cater to both the administrative and monitoring requirements of the users.

Created a dynamic forum specifically designed for university students, aimed at facilitating knowledge-sharing and establishing a stronger sense of community within the student body. The forum enables students to ask questions related to the subjects discussed in their classes, fostering active discussion and collaborative learning. By encouraging students to participate and share their perspectives, the forum helps to create a more connected group of learners, promoting a culture of knowledge-sharing and mutual support. This platform serves as a valuable resource for students seeking to deepen their understanding of course material and connect with like-minded individuals.

Led the development and refactoring of an HR management web application using the MERN stack. This versatile platform provides a range of essential functionalities, including daily report checking, task organization, job application storage and display, weekly email communication, and automated company task management. Through careful refactoring and attention to detail, I was able to enhance the application's efficiency and usability, making it an indispensable tool for HR professionals. This powerful platform streamlines a variety of tasks, reducing manual workload and increasing productivity across the organization. Overall, this project reflects my commitment to delivering reliable and innovative software solutions that empower users and improve business outcomes.

Developed a native mobile application for the "Feira Nacional de Artesanato" (National Portuguese Artisan's Fair) aimed at creating a dynamic social network that connects crafters with the public. This innovative platform offers a range of essential features, including interactive maps, exhibitor listings, and product catalogs, providing users with an immersive and informative experience. Through this mobile app, users can connect with their favorite crafters, explore the fairgrounds, and discover new and exciting products. The social networking aspect of the app allows for real-time communication between users, fostering an environment of collaboration and community building. Overall, this mobile application serves as a powerful tool for artisans and fair-goers alike, enhancing the overall experience and promoting the unique cultural heritage of Portuguese artisanship.

Created a web application that utilized vanilla JavaScript, HTML, and CSS to manage geolocation data for street libraries. The application provided a user-friendly interface for managing book stocks, handling fines for late returns, and tracking library locations via geolocation data. Through this project, I gained valuable experience in web development and honed my skills in JavaScript, HTML, and CSS. While the project may have been one of my first, it was an important stepping stone in my career and helped to set me on the path to becoming an accomplished developer. Overall, this project represents an important milestone in my journey as a developer and serves as a testament to my commitment to creating innovative solutions that leverage cutting-edge technology to address real-world challenges.

Developed a unique and engaging game using Python and VPython. The game utilized momentum and collisions to create a fun gameplay experience in which players were represented by balls and had to score on the opposing team's goal. In addition, the game featured a second minigame in which players engaged in a sumo match, vying to see who could stay in the ring the longest. One of the most distinctive features of the game was its intentionally challenging control scheme, which required players to adjust their direction vector using the arrow keys. This approach added an element of unpredictability and created moments of hilarity and unexpected gameplay outcomes, making the game both challenging and entertaining. Through this project, I was able to hone my skills in Python and VPython, while also exploring new approaches to game design and user experience.

Utilized NASA's fire watch API to develop a React application that enables users to keep track of the location, timelapse, and other relevant information about fires around the world. The idea behind this project was to challenge me to create a unique and engaging neomorphic design using React and plain CSS3. Through this project, I was able to showcase my skills in front-end development and design, as well as my ability to leverage powerful APIs to create impactful applications. Additionally, the project allowed me to stay up-to-date with current events and raise awareness about the global issue of wildfires. Overall, this project was both challenging and rewarding, and it showcases my passion for developing innovative applications that make a positive impact in the world.

Created a full-stack application focused on open house management, allowing admins to keep track of and manage possible visitors. The project was designed to hone my skills in TypeScript and Vue and to showcase my ability to follow clean architectural patterns on both sides of the development spectrum. Through this project, I was able to develop my skills in front-end and back-end development, as well as my ability to integrate various technologies to create a seamless user experience. The application allowed me to leverage my experience with TypeScript and Vue to create a robust, efficient, and user-friendly application. Overall, this project was both challenging and rewarding, and it showcases my passion for developing innovative and practical applications that improve the lives of others.
