About Me

Finding out about me!

Hello, my name is Roy Bailey!

Software Engineering requires logic for robustness, creativity for problem solving, adaptability for continuous learning. That's why it's one of the most demanding yet rewarding jobs in the world!

User Centric

Very client focused and prefer talking directly with customers. Always delivering pragmatic commercial solutions based on constraints.

Quality Coding

Lead by example, hands on coding, working alongside existing teams to ensure knowledge sharing, coaching, and best outcome.

Simple Solutions

Over two decades of experience designing solutions. Good software should reduce complexity.


Agile delivery with a responsive collaborative approach to technical and delivery challenges.

I am a highly skilled Technical Manager & Software Engineer. My client and delivery focused approach brings clarity and simplicity to the biggest challenges. Ideally suited to roles involving full ownership of technical solutions. I enjoy deep technical and business challenges while remaining close to the day to day design, implementation, and customers. Always building successful software solutions and productive technical teams whether commercial products or large enterprise systems. Always self taught new business domains and new technologies. Always delivering!

What makes me unique is my ability to abstract complexity from all the people and technical dimensions into simple reliable solutions.

A career doing your hobby is the best recipe for success!

Described as having a servant leadership style I create highly motivated and high performing engineering teams.

"Leaders must either invest a reasonable amount of time attending to fears and feelings, or an unreasonable amount of time trying to manage ineffective and unproductive behaviour."

To be successful today you need to build an inclusive and supportive engineering culture. A culture that encourages the best ideas to win, not politics or titles. This is where my many years of technical and commercial experience excels, providing relationship management between business and engineering and ensuring collaboration drives shared success.
