Venture FundingWhat this is
Most AI content is theory. This is practice.
I'm a veteran, engineer, and one-person studio operating at the intersection of SaaS architecture, AI integration, and production video — in Lake Geneva, Wisconsin. jsai.dev is where I document what I'm actually building with AI tools: what worked, what failed, what it cost, and what it replaced.
No demos. No hype cycles. Running systems or nothing.
Four Rules. No Exceptions.
Real Problems
Every experiment has a target. A measurable outcome. An actual human on the other end who benefits if it works.
Ship or It Doesn't Exist
I don't write about things I'm planning to build. I write about things I built. The draft, the failure, the version that worked — those all count.
One Engineer
No dilution. I own every decision: the schema, the API contract, the UX, the production deploy, the 3 a.m. incident.
Discipline Over Hype
Rust-inspired engineering philosophy applied to every layer: explicit errors, typed contracts, zero silent failures, minimal dependencies.
"Make it work. Make it right. Make it fast. In that order."
