About Me

Hello, I’m Jonatthan Medalla!

Programmer Analyst with an educational background in Computer Engineering and over 22 years of experience in IT. I combine a solid foundation in full stack development with skills in SQL, Python, and Power BI to build robust, data-centric solutions.

During my internship at Soprole, I led the migration of 22 Excel reports to Power BI, reducing the technical debt of the Data Consistency area. I am proficient in Django, React, Node.js, and AWS, and currently in my final year of Computer Engineering at INACAP.

I am seeking opportunities as a developer where I can apply my analytical vision and multidisciplinary experience to create high-impact software.
