I am a focused and results-oriented IT professional with more than nine years of experience. Within those years, I have helped both companies and individual developers get the most of their database setups, guaranteeing performance and stability. I prefer simple and intuitive solutions. At the same time, I like to dedicate time to learn new technical and soft skills in order to further enhance my abilities. My core technical skills involve (non)relational Database Management (full stack), BI, Big Data Analysis and Programming. My personal skills include easy adaptation to new challenges and scenarios, hard work, effective communication, humility and attention to details.
