Jessica Brentnall is an Architecture & Engineering Leadership Consultant who helps organisations navigate the realities of complex, ageing software. Drawing on her background in senior technical leadership, she bridges the gap between commercial ambitions, product strategy, and technical execution, ensuring systems remain performant, audit-ready, and fit for purpose.

She specialises in taking "pre-loved" platforms built with good intentions that have since accumulated heavy technical debt, and turning them into resilient, secure systems without harming delivery. Rather than advocating for costly rewrites, she pragmatically evolves systems, processes, and team structures together. She shares hard-won lessons from the trenches, offering a candid and practical perspective on leading teams through genuine, lasting technical and cultural transformation.
