I build inventory systems, routing algorithms, and the infrastructure nobody sees until it breaks at 2 AM.

Currently, I’m Technology Product Owner Lead at Paragon, where I own the supply-chain product line: inventory, material resource planning, and the work of keeping the two agreeing with each other. I also lead the push to get AI genuinely used across the company rather than merely installed.

Outside work I race: road, trail, water, and everything between.

Eight years across mining, consulting, marketplace and manufacturing. Same job in all four: work out what the problem actually is, then fix it.

8 years building.
Four industries, one habit: find the real problem first.
From mining to marketplace to manufacturing.

  5. 1819

    IT Project Manager

    Sinarmas Mining

    The translator between business users and IT: working out what they actually needed, deciding whether to build it in-house or buy it, then assessing and steering the vendors who built it.

This & That.

Work is half the story. The other half happens before 6 AM.

Swimming came first, back in elementary school. Then a long gap, then road running, then trail running up a volcano I had no business being on. The bike came last, and I’m still the one getting dropped. Combined two of them in an aquathlon: 500 m swim, 5 km run, one clock. Next: Ironman 70.3 in 2027.

Work with me.

I race road, trail, water, and aquathlon, and I document all of it. Race reports on Medium, training logs on Strava, the day-to-day on Instagram.

What a partnership looks like: I run your product across a real training block and write the honest version, splits and all.

Other conversations are open. A role, a company you’re building, or a problem you think I’d want to look at. Write to me and you’ll hear back within 2 working days, CV included if that’s what you need. Everything material is on LinkedIn.
