大野 ・ PortfolioMay 2026Based in Orlando, FL

Software developer,
architect & project
manager in the AI era.

By day I write production C#, .NET and PostgreSQL at Coral Vita. After hours I architect and ship indie products end-to-end — Cronradar, HumanProof × Shinsotsu, Ashbase, NeuroEval and more.

From IT internships to founding a studio to a full-time engineering seat: I own the problem, ship the fix, and keep one foot in the codebase and one in the roadmap.

Five years of getting things shipped.

From IT internships to founding a studio to a full-time engineering seat — same job under different titles: own the problem, ship the fix.

The stack I reach for when the brief says “ship it.”

No new toys when the boring ones still work. AI is a tool, not a religion. Picked for joy of debugging, not novelty.

Things I've built, shipped, and am still testing.

One flagship in production, a handful of products in active research, and two ongoing investigations into AI-era cognitive work.
