Programmer | Problem solver

I am problem solver with over 5 years of experience in solving programming problems (3 years in data industry). My adventure with technology started with a deep curiosity about how I can create with code, which led me to explore different programming languages, frameworks and development tools. I enjoy solving complex problems, prototyping MVPs and creating things that people need. Actually focusing on Data Engineering, Business Inteligence and AI Tools
