Technology projects rarely fail because of technology. They fail because priorities aren’t aligned, communication breaks down, risks aren’t managed early enough, or teams aren’t working toward the same goal. That’s where I come in. For the past 17+ years I’ve been helping technology companies build stronger delivery organizations, improve operations, lead cross-functional programs, and solve complex execution challenges. I’ve managed global teams across Europe, the UK, India, and North America, worked with Fortune 500 customers, and partnered closely with Product, Engineering, Customer Success, Professional Services, and executive leadership. Most of my work sits where technology meets business. Whether it’s leading a large implementation, improving delivery processes, building governance frameworks, scaling support and cloud operations, or helping teams adopt AI into their daily workflows, my focus is always the same: make execution simpler, more predictable, and easier to scale. I enjoy stepping into situations where there are too many moving parts, unclear ownership, or growing operational complexity. Bringing structure, aligning stakeholders, and helping teams deliver successfully is what I’ve spent my career doing. I can help with: • Technical Program & Project Management • PMO setup and delivery governance • Cross-functional program leadership • IT Operations & Cloud Operations • Service Delivery Management • Executive reporting & stakeholder management • Process improvement & operational excellence • AI workflow adoption and automation • Customer onboarding & implementation programs • Team leadership, coaching, and organizational scaling If you’re looking for someone who can keep projects moving, bring clarity to complex initiatives, and work comfortably with both engineers and executives, I’d be happy to discuss your project.
