All my life I have been passionate about architecture / software design, as this is the cornerstone to a maintainable and extensible application. As such, I have enjoyed exploring some crazy ideas and discovering that they are not so crazy after all. I also love writing about my ideas and seeing the community response. As a consultant, I've enjoyed working in a wide range of industries such as aerospace, boatyard management, remote sensing, emergency services / data management, and casino operations. I've done a variety of pro-bono work non-profit organizations related to nature conservancy, drug recovery and women's health.

Spain Spain
mbarbac has worked in start-ups, multinational tech companies, and consulting ones, serving as CIO, CTO, SW Development Director, and Consulting Director, among many other roles.

Solving complex puzzles and getting out of them business value has ever been among his main interests - and that's why he has spent his latest 25 years trying to combine his degree in Theoretical Physics with his MBA... and he is still trying to figure out how all these things can fit together.

Even if flying a lot across many countries, along with the long working days that are customary in IT management and Consultancy, he can say that, after all, he lives in Spain (at least the weekends).

I started my IT career in programming on different embedded devices since 1992, such as credit card readers, smart card readers and Palm Pilot.

Since 2000, I have mostly been developing business applications on Windows platforms while also developing some tools for myself and developers around the world, so we developers could focus more on delivering business values rather than repetitive tasks of handling technical details.

Beside technical works, I enjoy reading literatures, playing balls, cooking and gardening.
