About

I’m Bruno, a Backend Developer with over 10 years of experience in C#, specialized in building high-performance, scalable applications that solve real-world challenges. Throughout my career, I have worked with Windows Forms, Web Forms, ASP.NET Web API, and ASP.NET Web App, always focusing on efficiency, maintainability, and best practices. My expertise spans database communication using Entity Framework, API integration, and system architecture, ensuring robust and optimized solutions. One of my most impactful contributions was designing and implementing high-performance systems in C# with ASP.NET Core, including an access control platform that integrated facial recognition, biometrics, card readers, and LPR cameras through REST APIs and socket communication — significantly improving processing speed and scalability. I also developed and optimized automated Web APIs that improved operational efficiency by over 60%, enabling real-time invoice generation and instant shipment tracking via WhatsApp and Correios integration. Additionally, I have hands-on experience with React.js, building modern, responsive interfaces that integrate seamlessly with .NET APIs to deliver cohesive, full-stack solution Beyond technical expertise, I’m passionate about optimizing processes, sharing knowledge, and fostering team growth. My goal is to make a meaningful impact wherever I go — contributing not only through high-quality software but also by mentoring and elevating those around me. Let’s connect and build something great together!

I continued front-end development using React.js for a new company project, with a focus on centralizing and unifying the data of parking in the cloud. The system was projected to optimize remote management by administrators, offering a modern interface, a responsive interface, and integration with the backend through REST requests to the API.
I played a key role as the most experienced development team member, supporting colleagues in technical challenges, assisting in development, and reviewing code, focusing on maintaining clean and well-structured code. I worked on various applications using C#, ASP.NET Web API, ASP.NET Framework, Windows Forms, and ASP.NET Web App. Additionally, I utilized tools like Git and Bitbucket to ensure efficient version control and a collaborative code review process. My commitment to best practices and organization directly contributed to the team's growth, increasing productivity and delivering better results for the company.
I developed a system for controlling access devices, including facial recognition, biometrics, card readers, and LPR cameras via REST API and socket. This solution significantly improved data reading and processing speed, solving a critical issue for the company. In addition to designing and implementing the application, I also integrated devices from various well-known brands. The system was built using C# with ASP.NET Core 6, ensuring high performance and scalability.
I developed Web APIs in C# integrated with SQL Server and MongoDB databases, using Entity Framework for relational data management. These APIs were responsible for centralizing the business logic of the company's core systems, including access control and parking management. The solution ensured greater efficiency, scalability, and simplified maintenance, optimizing essential processes for the operations.

I developed an integration with the WhatsApp API and a microservice to monitor product status and automatically notify customers of each update. This solution reduced support demand by eliminating the need for customers to call for order information. The microservice, developed in C# with ASP.NET Core 5, monitors status changes and triggers the Web API, which sends real-time notifications via WhatsApp, improving the customer experience and relieving the support team.
I developed an integration with the Brazilian Postal Service (Correios) system to automate the retrieval of tracking codes, solving a recurring issue for the company where customers had to wait about two days for the code. With the integration, as soon as the sale is completed, the data is automatically sent to Correios, generating the tracking code and sending it instantly to the customer's WhatsApp, improving the user experience and reducing support demand. The solution was built as an API in C# with ASP.NET Core 5, integrated with Correios system and the company’s sales system, and developed in C# with WebForms.
I developed a feature that accelerated the creation and real-time sending of invoices, allowing multiple invoices to be issued simultaneously, resulting in a 60% increase in the number of sent invoices and solving a critical issue. The solution was built as a Web API in C# with ASP.NET Core 5 and Entity Framework Core, integrated with an external invoice management API and the company’s web system, developed in C# with WebForms.

I migrated a condominium access control system, originally developed in VB6, to a web application using C#, ASP.NET Core 5, and MVC architecture. This transformation not only improved the customer experience but also enabled the creation of new features that were not possible with the old language, expanding the system's functionality and providing a more modern, scalable, and maintainable solution.
I performed maintenance and developed new features for the company's access control and parking control systems, always focusing on improving the user experience. These systems, originally developed in VB6, were enhanced to ensure greater efficiency and usability and to meet the company's growing needs.
