I’m a physics student with experience in data analysis, computational problem-solving, and the development of software that turns real-world signals into usable outcomes. My training has strengthened my ability to use numerical methods and computational algorithms to interpret and process experimental data.

I’ve taught Python and supported students through structured, assessment-focused instruction. I’ve also worked with data and image analysis, identifying gaps and driving continuous improvement through targeted practice and evaluations.

As a Full-Stack Developer at Digital House (Remote), I created a website for a store of musical instruments and built the backend in Java with Spring Boot and SQL connections. I also wrote unit tests to ensure the backend works correctly and delivers reliable functionality.

On my projects side, I developed a REST API in Node.js and Express to calculate business days from a start date, excluding weekends and Colombia holidays. I designed the code modularly (controllers/services/helpers), implemented centralized error handling and input validation, and validated endpoints with Postman while optimizing date-range calculations.
