Hi, I’m Mark.I lead teams that buildthings people actually use

Engineering manager in Singapore. By day I lead engineering teams. After hours I make my own apps and photograph the places I travel to.

Nice to meet you.

I’ve spent over a decade turning messy problems into simple products, and building the teams that ship them.

I started out as a developer in Manila in 2015 and have moved between building and leading teams ever since.

I care about the details people feel but rarely notice: the form that asks only for what it needs, the sentence that says just enough, the release that goes out on a Tuesday and nobody has to talk about on Wednesday.

What’s it like to work with me?

Away from screens, I photograph landscapes
