About me

Software Engineer by trade. Founder by nature. I operate at the intersection of Engineering and Hard Tech. Currently shipping code at App'Ines while building Entropy, a network for World's most ambitious engineers.

I am obsessive about quality and speed. Whether I am optimizing an Angular frontend, architecting a Node.js backend, or diving into C++ for astrophysics simulations, my goal is the same: to bring order to chaos. I believe the best software is built with the precision of a Swiss watch and the ambition of a space program.

Software Engineering

Proficient in a variety of programming languages and frameworks, with a focus on building scalable and efficient software solutions.

Data Science

Experienced in data analysis, machine learning, and data visualization, with a passion for extracting insights from complex datasets.

Astrophysics

Fascinated by the mysteries of the universe, I enjoy exploring the latest advancements in astronomy and contributing to Citizen Science projects.

Problem-Solving

I thrive on tackling complex challenges, leveraging my analytical skills and creative thinking to develop innovative solutions.
