Services

Senior engineering for products that handle sensitive data.

Three ways to work together, each led and delivered by me. Pick the one that matches where you are; we can change shape as the work does.

01Monthly retainer

Fractional CTO

Senior technical leadership without a full-time hire. I own the architecture, the roadmap and the hard calls — and I still write the code.

Best for: Founders and operators who need one accountable technical owner.

What's included

  • Architecture, roadmap and build-vs-buy decisions
  • Hands-on engineering on the critical path
  • Vendor, agency and contractor oversight
  • Compliance posture for HIPAA, GDPR and PIPEDA

02Fixed-scope sprint

AI for regulated teams

Give your staff Claude without sending sensitive data somewhere it shouldn't go. Covered by your BAA or DPA, wired into the tools they already use.

Best for: Health, wellness and education teams that handle PHI or student data.

What's included

  • Claude via AWS Bedrock or Azure under your BAA/DPA
  • Connectors to Microsoft 365 and internal systems
  • SSO, device management and audit logging
  • An internal app platform for shipping AI tools safely

032 weeks · fixed price

Codebase takeover audit

Inherited an app from an agency or a departed team? I'll tell you what you actually own, what's at risk, and what to fix first.

Best for: Companies taking ownership of software someone else built.

What's included

  • Architecture and code-quality review
  • Security and compliance gap report (HIPAA / GDPR)
  • Infrastructure and deployment assessment
  • A prioritised 90-day plan — I can execute it, or your team can

How it works

From first call to production.

  1. 01

    Call

    30 minutes on what you're building, what's in the way, and whether I'm the right person for it.

  2. 02

    Written proposal

    Scope, approach, timeline and a fixed price or retainer — within a few days, in plain language.

  3. 03

    Build

    Weekly demos of working software, not status reports. You see progress in your own environment.

  4. 04

    Hand-over or stay on

    Documentation and infrastructure as code, so your team can own it — or I keep running it.

Not sure which fits?

Tell me where you are and I'll recommend the smallest engagement that gets you somewhere real.
