Technical partner for founders

Four areas, one operator.

Technical leadership, AI systems, operating systems for teams, and the whole estate underneath. Most engagements touch more than one, and all of them start the same way.

01

Technical leadership

Architecture, hiring, unit cost

You have engineers and nobody setting the standard. I take the architecture and delivery decisions, so the pieces fit and the same problem stops being solved four different ways. I hire against an assessment I wrote, and I train the engineers you already have.

What I build

Architecture and delivery standards across every system the team ships

Technical assessments that measure how someone directs AI inside an existing architecture

Unit cost ownership, with a ceiling and an alert before anything switches on

Training for your engineers, not a dependency on mine

02

AI systems

n8n, Python, Claude

Decisions live in code and judgment lives in prompts, never the reverse. Every build ships with a test suite, a monthly running cost you see before it starts, and a handover pack your team can run without me.

What I build

Document and PDF extraction with multi-pass consensus and per-cell source verification

Agents wired into your CRM, inbox and ops stack, with approval gates on expensive steps

Churn recovery, inbound triage and lifecycle flows triggered on real signals

Content pipelines priced per finished post, with the monthly bill shown before the build

03

Operating systems for teams

Notion, ClickUp, CRM

One source of truth, and capacity you see before it breaks. Sized to your team rather than a template, and built so your operators own it after handover.

What I build

Custom Notion or ClickUp workspaces with role-based views

Roadmap and scope-discipline structures product teams stick to

Reports where every number links back to the row it came from

Documentation, runbooks and onboarding paths your team owns

04

The whole estate

Access, security, and cost per unit

The parts nobody owns until they break. Account migrations, credential rotation, offboarding, security posture, and what every running system costs per unit. This is where a diagnostic usually finds the money.

What I build

As-is architecture maps of systems nobody has documented

Account ownership, credential rotation and offboarding that survives a departure

Return-per-workflow audits, with the negative ones decommissioned

Self-hosted infrastructure on your own servers, with encrypted off-box backups

It starts the same way every time.

Read-only access for two or three days, then a written recommendation. From there we decide whether there is a build, a partnership, or nothing.

Fixed price on a build, or a monthly partnership. Never an hourly rate.
