Sheet 00 · Cover Drawn for the founder considering senior engineering help 2026 · Rev. 1

Senior judgment, not headcount.

Fixed-price AI feature builds from $3,000. White-label sites for agencies at $1,500. Fractional CTO from $2,500 a month.

I help founders and CTOs ship the work that compounds. AI features that hold up in production. Platforms that survive the second year. Architectural calls that do not have to be unwound at Series A.

Four engagement shapes, each priced before work starts. Full product builds are quoted as one fixed price after a free scoping call. Every build ships with a 30 day stabilization window.

Or run the fit check first.

Shape 03Fractional CTO

Senior judgment, weekly, on the architecture decisions that compound.

For founders or heads of engineering who do not need a full time CTO. Architecture reviews, hiring panels for senior roles, vendor evaluations, board prep on the technical narrative, and the calls outside the sprint board.

Sheet 02WorkSelected platforms

Production systems, shipped.

Three production platforms across real time geospatial, content streaming, and consumer software. Architected end to end, operated long enough to learn what the first design got wrong.

Notes from the build floor.

Pricing transparency. Fractional CTO mechanics. Replatforming framework. Cross-border hiring diligence. AI integration cost in regulated industries. Read what the studio actually does before booking the call.

Sheet 04AboutThe operator

A solo practice, by design.

The studio operates as a senior solo practice with AI tooling deeply integrated and senior contractors brought in on specific scopes. Continuity is built into the engagement model.

Thirteen plus years shipping production engineering. Architecture chops on real time systems, AI feature integration into shipped products, regulated-industry build constraints, and the senior hires that come with growing engineering teams from two to twenty.

The previous shape, a seven person team between 2022 and 2024, was deliberately wound down once AI tooling matured to the point where one senior operator and a tight contractor bench could deliver the focused work scale-ups actually need.

Continuity is contractual, not goodwill. Every retainer includes a written handover plan in the SOW. Every build engagement ships with documentation and runbooks the client team owns at handoff. Every engagement is priced in writing before work starts.
