Hi, I’m Declan Butler

I began my software engineering career in 2005. Over the past two decades, I’ve progressed from developer to engineering leader — shaping large-scale operational platforms, empowering high-performing teams, and driving cloud transformation across the airline industry.

I’m passionate about scaling people and systems. I create environments where engineers grow, where architecture simplifies complexity, and where delivery meets impact.

Career Highlights

• Led the cloud transformation of check-in and baggage systems, retiring legacy IBM stacks
• Rolled out a graduate hiring & onboarding program, onboarding 20+ engineers since 2021
• Drove delivery of regulatory and operational initiatives like EES, Verifly, and cabin bag rules

I believe great engineering leaders scale themselves through others — by setting clear direction, creating psychological safety, and obsessing over impact.

Let’s build something that matters.
