Principal Architect &
Fractional Engineering Leader

Principal Architect and Fractional Technical Leader. I help scaling teams build infrastructure that holds under pressure, and stabilise systems that have already broken.

What I Do

Senior engineering leadership across the full delivery lifecycle

Fractional CTO

Strategic engineering leadership embedded part-time in your organisation — without the full-time headcount cost.

Principal Architect

Deep-level system design and architectural decision-making that keeps your platform scalable and maintainable as you grow.

Interim Engineering Lead

Hands-on engineering leadership during transitions, hiring freezes, or while you search for the right permanent hire.

Technical Due Diligence

Structured assessment of codebase, infrastructure, and engineering team ahead of acquisition, investment, or partnership.

Greenfield Builds

From blank canvas to production: architecture, implementation, and operational runbook for new products and platforms.

Recovery & Stabilisation

Diagnose and resolve performance degradation, reliability failures, and accumulated architectural debt under pressure.
