SKILLS
ABOUT WARREN BARTON
I’m an engineering and technology leader with over 20 years’ experience modernising complex platforms in regulated Financial Services environments.I’ve led and transformed engineering organisations of up to 70 people across the UK and India, building modern delivery capability while tackling deep technical debt in legacy estates. My work has spanned large-scale API and middleware modernisation, cloud migration, digital front-end delivery, and the transition from traditional waterfall programmes to Agile operating models.I operate at the intersection of technology, people, and delivery, making pragmatic, technology-agnostic decisions that balance customer outcomes, risk, cost, and long-term sustainability. I’m particularly experienced in turning under-invested or fragmented engineering areas into coherent, scalable platforms by building teams with a strong engineering culture and accountability.Alongside deep technical and delivery experience, I bring a strong strategic lens, reinforced through the Henley Business School Executive MBA. This has sharpened my focus on prioritisation, organisational design, and ensuring technology investment delivers measurable business value.My career includes multiple major acquisitions (Equitable Life → Halifax, HBOS → Lloyds), giving me first-hand experience of integration, restructuring, and operating-model change at scale.I’m motivated by building high-performing teams, developing future leaders, and leaving technology estates materially better than I found them.
