I build backends and data systems that hold up in production — for companies, NGOs, and for the ocean.

For companies

You've got data that should be doing more, or a backend that wakes you up at 2am?

I fix both. 

Ten years of shipping backends and data platforms that survive real load — I like owning a problem end to end.
Not just showing up for the spoils.

For NGOs and researchers

Working toward something good for the ocean? I'd love to hear about it.
If data or the tech side of it is what's slowing you down, I'm happy to help however I can: cheap infrastructure for your grant, spare hands for field data collection or just an hour of my time.

Field notes

War stories, dive logs, and how I built things by repeatedly failing. If you like engineering told straight, with the failures left in, this is the section for you.

Selected work

Ocean

Calm logic, steady decisions
and ocean-deep patience.
