03 / About
A generalist
by design.
I’m JBrien Barcoma, a designer and maker based in Singapore with a focus on data science & analytics.
My experience crosses architectural design, project and operations management, and biotech and aerospace manufacturing. I like the moment when different disciplines begin speaking to each other.
This website is my public workbench: part portfolio, part learning log, and always a work in progress. The archive keeps the earlier versions visible because the path matters too.
04 / Side quests
Other rooms
in the workshop.
Hobby portfolios and subject-specific experiments. Some are rough, some are dormant, and all are part of the map.
