Building things that just work, and having fun while making them happen.

About

I'm a developer with a love for building things that just work; no unnecessary fluff, just clean, functional code that gets the job done. I thrive in environments where I can create simple, efficient solutions and have fun along the way.

Currently, I'm a software engineer at Juliahub, with a particular focus on data-intensive components for the frontend. I contribute to shaping the Juliahub platform, ensuring users have a smooth experience when navigating complex data, all while optimizing performance and scalability across the stack.

In the past, I've had the opportunity to develop software in diverse areas, from edtech to cms, working with teams ranging from startups to large corporations. Additionally, I also authored a book on data visualization. It takes readers through the history and evolution of the field, providing guidance on selecting the right visual methods and tools for communicating data effectively.

In my free time, I'm usually reading sci-fi, playing volleyball, or doing fun tech experiments.
