About Me

I'm Leonardo Costa, a full stack developer with a specialization in backend development. Born in São Gonçalo, Rio de Janeiro, I'm now based in Belém, Pará, Brazil—a city that has welcomed me and where I'm building my career in technology.

My passion for technology started early, at age 3, when I had my first encounter with a computer back in Rio de Janeiro. Since then, I've been an enthusiast of computing, constantly exploring and learning about this fascinating universe.

I officially began my professional programming journey in 2022 when I enrolled at the University of Amazonia. It was there that I transformed my passion into structured technical knowledge and took my first steps toward my career as a developer.

My programming journey has been marked by constant learning and growth. I work primarily with Python and Django, frameworks that enable me to create robust and scalable web applications. I specialize in Django REST Framework, developing efficient and well-documented RESTful APIs.

In the JavaScript ecosystem, I use both Node.js and Bun for backend development. On the frontend, I have solid experience with Vue.js and React.js, always striving to create intuitive and performant interfaces. I leverage Nuxt.js and Next.js for server-side rendering and static site generation applications.

Along the way, I've faced various challenges that taught me valuable lessons about resilience, problem-solving, and the importance of adaptation. Each obstacle overcome has made me a more complete professional, better prepared for future challenges.

I believe technology should be a tool for solving real problems and improving people's lives. That's why I always strive for:

• Quality above all: clean, well-documented, and tested code
• Continuous learning: the tech world evolves rapidly, and evolving alongside it is essential
• Collaboration: the best results come from teamwork and knowledge sharing
• Honesty and transparency: in communication with clients and colleagues
• Resilience: viewing challenges as opportunities for growth

As a full stack developer specialized in backend, my focus is on:

• REST API Development: using Django REST Framework to create efficient and well-documented endpoints
• Systems Architecture: planning and implementing scalable and maintainable solutions
• Frontend Development: building modern interfaces with Vue.js/Nuxt.js or React.js/Next.js
• Systems Integration: connecting different services and APIs
• Performance Optimization: ensuring fast and responsive applications
• Best Practices: automated testing, Git version control, and agile methodologies
