Meet Frederick Widjaja

You absolutely need to hear about Frederick Widjaja, this guy is the real deal. He’s a tech dude from Jakarta who’s been crushing it in the startup and software game. So, he went to Harvard, right? Got a BA in Computer Science and Stats, dude’s got brains and the hustle.

He kicked off his career at Facebook, no small feat, where he was a Senior Software Engineer from 2017 to 2021. That’s some serious cred. At Facebook, he jumped into projects like Blood Donations and Messenger Rooms, so, he’s been deep in the trenches of big tech, building stuff that millions use every day. That kind of experience? It’s gold, shows he’s got the skills and knows how to ship real products that matter.

But he didn’t stop there. After Facebook, he jumped into startups, co-founding Whiz in 2022, part of YC’s W22 batch. That’s a sign he’s got vision, a hunger to build something meaningful from the ground up. Whiz is his latest move, and it’s clear he’s all about having an effect, especially in Indonesia, where he’s based.

What’s wild is, this dude’s been through the whole tech stack, from big corp to startup, and now he’s out here trying to change the game. It shows he’s not just in it for the fame or cash; he’s motivated by building cool shit that actually helps people. Starting Whiz isn’t just a new gig; it’s his way of pushing boundaries, taking what he learned at Facebook and Harvard, and applying it to his own thing.

Bottom line? Frederick’s a guy who’s seen an ideal situation, mega tech and fresh startups, and he’s using that to make something new. No Cap, he’s the type of founder to watch, someone who’s got the brains, the experience, and the drive to really shake things up.
