PLAYER PROFILE / THE HUMAN BEHIND ALT

One person.
A lot of side quests.

I’m Marvin. Most people call me Alter. I build websites, apps, games, and whatever the idea needs to become real.

✦ ABOUT / WHO'S BEHIND THIS

They call me Alter.

Birth certificate says Marvin Aguinaldo. Everyone else calls me Alter. Yeah, that's the "alt" in Alt Interactive Studios.

I studied Computer Science, then decided one job title wasn't enough. By day I'm a full-stack web dev: front end, back end, payments, and payroll that hits everybody's account on time, every time. Clients hand me the shit their business actually runs on, and I make it work.

Off the clock I build games, make UGC that doesn't feel like a fucking ad, and run the occasional crazy experiment, like the robot doing chores behind this page. Crazy, not apocalypse crazy. Nothing I build is going to fuck up the world. Pinky promise.

HOW I WORK / FROM IDEA TO SHIP

01

Find the real problem.

What should this do? Who is it for? What’s getting in the way? That’s where the project starts.

02

Design the whole thing.

The screen, the flow, the data, the small details. A good-looking front end needs a solid engine room.

03

Build. Play. Refine.

Get it working, put it through its paces, and make the experience feel right on both a phone and a desktop.
