I’m an experienced executive software architect with a proven track record of shaping and transforming organisations and software development processes.

Throughout my career, I have held various roles including CTO, Director of Engineering, Architect, Fullstack Developer, Scrum Master, Product Owner, and Project Manager, leading teams of up to 30 developers.

I have a strong background in defining and driving technological visions, as well as growing high-performing engineering teams.

I have worked with both startups and Fortune 500 companies, successfully delivering multiple projects and products across various domains. My expertise spans a wide range of technologies.

Even to this day, I continue to make valuable contributions in both hands-on programming and strategic decision-making. For example, I have led the design and implementation of a new micro-services architecture and created a roadmap for an organisation-wide technology transformation.

After spending over 20 years working in permanent roles, I made the decision to start my own consulting business and offer my services as a freelancer. This allows me the flexibility to choose the type of projects I work on, enabling me to engage in diverse and demanding projects at a fast pace, which I prefer. I’m committed to delivering the best possible quality, paying attention to both the bigger picture and the finer details, while remaining pragmatic and result-oriented.

My professional style has been greatly influenced by the Agile Manifesto, the Software Craftsmanship Manifesto, Lean Software Development and TQM. Among others, I have found inspiration in the works of individuals such as W. Edwards Deming, Peter Drucker, Robert C. Martin, and Martin Fowler, who have played a significant role in shaping my approach and aspirations.

I enjoy regularly reading HBR, Wired, Medium, Hackernoon, Food for Agile Thought, and The Exponential View among others.
