My name is Omar. I am an all hands-on leader in technology with more than 20 years of experience delivering software as cloud services in both leadership positions and as an individual contributor for a range of projects from start-up level to multinational companies. I am able to contribute in both the Technical and Business side of product development and have wide experience running organizations spread through different countries, as well as raising VC capital and board level interactions.

I have experience developing desktop and web-based applications in different fields such as Financial Services, Online video, Artificial Intelligence, and Tourism; both customer facing and internal, with particular focus in good software engineering practices and code quality.

Regarding Education, I got a Honours degree in Computational Systems Engineering from the Universidad Autonoma de BCS in Mexico, where I specialized in advanced software development. I received my PhD degree at the University of Liverpool, UK, for the research in multi-agent option-trading mechanisms for market-based control of distributed computational systems.

I was active for 7 years in academia during my PhD (thesis) and as a Research Associate in the project PRIMA where I was "work package coordinator" (the person in charge of coordinating the development of agent-based modelling and simulation systems for the project).

Although my main area of expertise is complex and scalabe systems in Finance, I am attracted to solving all kinds of Computer Science and Software Engineering related problems. I enjoy solving complex problems using leading edge technology tools and algorithms (Machine Learning, real time communication, and other cool technologies and algorithms).

One of the things that I enjoy the most, is preaching (including setting the example) the use of "proper" software engineering practices to build good software (i.e., unit testing, CI testing, using [but not abusing] design patterns, code reviewing, etc).
