About
Formal education and background
Education
Information Systems Engineer with a Master's in Information Systems Engineering (2023) and a Master's in Artificial Intelligence (2025).
Story
Arsysco started as a side entrepreneurship, building web applications for local clients from 2014 to 2021 while I grew through data-focused roles. JJ Trending is the next chapter, where I share what I have learned about data systems and engineering.
Arsysco, the early days
A brief tribute to the first site that started it all, honoring the work, the clients, and the late nights that shaped JJ Trending.
2014 to 2021
Built with local energy
Arsysco was my initial brand, created to enable the dream of building software and helping local businesses with their challenges. It is nostalgic, but also a reminder that great systems start with listening to people.
I was lucky to have collaboration from friends along the way. That spirit still lives here: reliable engineering, clear communication, and a love for practical outcomes.
