 Jill Cowie, Product Owner (Intermediary Enablement Old Mutual Life Assurance Company (SA) Limited)

Marius has been an awesome source of information and technical insight. His solutions promote innovation, efficiency and encourage personal growth and insight for those who interact with his work. He is an absolute pleasure to work with and that is evident in the fact that I have grown as a developer through interacting with him and just feeding off his wealth of knowledge which he is very willing to share. I cannot reiterate enough how much of a pleasure it is working with him and can only hope to work with him more as it can only be a positive for anyone that aspires to achieve success in fields that benefit from his skill set and the human being himself...

Mutende Msiska, Analyst Programmer (CC Solution Delivery, Old Mutual Life Assurance Company (SA) Limited)

I've had the pleasure of working with Marius on the Old Mutual OFP project. What an incredible guy. Well versed on both Front-End (Angular) and Back-End (Java) technologies. I would definitely work with him more given the opportunity. He joined the project hitting the ground running & sprinting I must say. To top it off he's a people person. He got along with everyone in the team. It was great working with you man. Keep up the good work...

Marius has incredible depth of knowledge in software development, architecture and processes. Name any technical topic and he could give you an in-depth lecture on it. Not only is his theoretical base of understanding extremely sound, but he also has extensive experience and a myriad of ideas on implementation and problem-solving. He is the type of person who never gives up until a problem is solved. He is highly self-disciplined, resilient under pressure and very adaptable to project situations that, in the business world, can range from dire to awkward. On top of that, he is a very friendly and helpful person to work with. Any company would be extremely fortunate to have Marius lead their team into the 21st century.

 Robert Laniewsky, Senior Java EE Developer

This was my first iPhone app to have programmed and Marius did a fantastic job. It took a little longer than was planned due to some technical requirements that came up, but Marius solved for them. He even suggested a few UI issues that made the end product even better than I hoped. I will definitely use Marius again. You can see the app he did at http://www.watchmechangeapp.com
