My first love was Visual Arts — but somewhere along the way, my laziness became my greatest superpower. I hated repetitive work so much, I taught myself to automate it away. That's how a painter became a programmer. ☕

About Me

WHO I AM

I'm Joe Ed Mialen — a Professional Licensed Educator, a visual artist at heart, and an accidental programmer.

My first passion was Visual Arts. Painting with a brush, sketching on paper, then eventually digital design and Photoshop — that's where I started. But then real work arrived: reports, computations, repetitive tasks stacking up on a teacher's desk every single day.

Here's the truth: I was too lazy to do it manually. So I automated it. It was 2014 when it all began — that one instinct, "there must be a faster way", pulled me into Excel formulas, then VBA, then PHP, SQL, Python, JavaScript, and beyond. Laziness, it turns out, is a surprisingly effective teacher.

Now I build tools that save other people from the same repetitive grind — starting with TSS, a free desktop app for DepEd teachers.

Artist Turned Automator
Before any line of code, there was a paintbrush. Traditional painting, drawing, then digital — Photoshop, computer graphics. The eye for design never left, it just found a new canvas: the screen.
