Founders and tech teams

I build and secure the backend so you can ship.

Supabase, edge functions, row level security, Stripe, AI agents and automations. I build production systems for my own companies every day and I check security first.

Bring your repo or Supabase project. You leave with the top three risks and fixes, whether we work together or not.

Why me

The trustworthy new local who does what he says.

My grandparents raised me in northern Minnesota, and I became their caretaker. That taught me to show up, follow through and take care of people.

I started Towslee's Got Pressure and did the cleaning myself. Running it showed me how much of a small business is busywork: quotes, follow ups, reviews, scheduling.

I went through insurance prelicensing and saw agents doing the same busywork by hand. So I started Quantum Arbor to build the systems I wished every small business had.

In October I moved to San Ramon to give this everything. I am the new local who answers his own phone, explains things in plain English and does what he says.
