The WitUS ecosystem — eight interlinked products under one philosophy.
I ship full-stack products, write about the work, teach it, and operate the platforms. The same person who designs the architecture answers the support tickets.
I'm targeting Developer Relations, Tech Support Engineer, and full-stack AI-product roles. The projects below are the evidence — shipped products with public URLs, public APIs, real users, and real production incidents I've recovered from.
Send a quick brief: role, team, stack, timeline, comp range if you have it. I respond personally within 24 hours during the work week.
Send a hiring brief →I'm open to integrations, co-marketing, grants, and joint ventures across the ecosystem — especially anything that makes one of the products below more useful, or expands its audience.
Tell me what you're imagining and which product(s) it touches. If it's a fit, you'll hear back fast.
Start a partnership conversation →Tier A — products with public URLs and active users. Solo builder/operator on each.
