Senior Software Developer | .NET 9 & Angular | AI-Assisted Engineering I am a Senior Software Developer specializing in designing and building robust, scalable, enterprise-grade software solutions. My focus goes beyond just writing code; I am passionate about clean, highly structured software engineering that guarantees long-term maintainability and high availability. I implement modern ecosystems based on Clean Architecture, Hexagonal Architecture, and Microservices, ensuring business logic is perfectly decoupled from infrastructure. I strictly follow a Code-First development methodology (EF Core) for database management to maintain absolute domain traceability, avoiding direct SQL editor manipulations. Additionally, I stay at the absolute forefront of modern software engineering by integrating advanced AI-assisted development workflows. I leverage frameworks like the Model Context Protocol (MCP), OpenCode, Aider, Ollama, and the Gemini API to accelerate development cycles, automate repetitive testing, and enforce strict architectural rules directly within the codebase. What I do best: High-Performance Backend: Developing robust APIs with .NET 9, implementing CQRS patterns, and handling asynchronous messaging with RabbitMQ. Modern Frontend: Crafting dynamic, optimized, and responsive web applications using Angular v21. Multi-Platform Solutions: Building cross-platform hybrid apps with MAUI and Blazor for unified web and mobile experiences. Complex Integrations: Implementing multi-tenant SaaS architectures, processing high-volume secure notifications, and integrating complex financial payment systems. If you are looking for a disciplined Senior Developer who brings architectural order, rigorous technical excellence, and cutting-edge AI efficiency to your project, let’s connect and discuss your goals.

It was the most important moment of my 13+ years of career. It was when I realized that there is always a trade-off in technology. You have to do something intentionally bad in order to succeed as a Small Medium Business in the Digital Transformation. And 70% fail because they insist on doing this very thing well. A while back, when I finally landed a job in a corporation, I was excited that I was going to use state-of-art technology. But, one of my first features immediately added some bugs. As I fixed those bugs, I introduced another, but also other bugs started to pop up caused by previous developers. In laymen terms, it is like a Rubik’s cube. As you carry on assembling the second face, you may accidentally mess up the first bit. It wasn’t like that when I started my career in technology in the civil service a long time ago. Yes, I was frustrated because we used old boring technology. But, we didn’t have to put out the fire all the time because that limited technology prevented us from getting in this position. Coincidence or not, the easiest way to solve the Rubik’s cube is putting constraints. If you move towards, you have to move backwards at some point. Fast forward to nowadays, some of my clients want to create highly customized User Experience. As the project starts to grow, hyper customization introduces more complexity. Then, you make a small change and get unexpected results. You didn't account for all the complex consequences. And this happens again and again, and you can’t avoid it. The software had become brittle. You start to miss deadlines or have to hire more developers to fix cracks faster, and eventually I get hired. That’s the time I have the hard talk: don’t bite more than you can chew, stop chasing the perfect User Experience (good User Interface is not a problem though) with a small team. If a BigTech didn’t have to hire thousands of engineers to provide that, they certainly wouldn’t. Anyway, User Experience is only noticed by B2C clients, and this is where Big Techs thrive. In B2B or internal tool software, who pays for the software won’t even use it. Hey, my name is João, I’m a software architect and developer, feel free to send me a message asking how I can make your business grow. What technologies do I work with? The simple ones: HTML, CSS, Bootstrap, Bash, XML, PostgreSQL, Apache Camel, Apache Knowledge Is Everything, Keycloak. If you need a hypercustomized solution, I can decently program in Java, Python and JavaScript, though. If you have any doubts, don’t hesitate to contact me.
