"We collaborated for Madfish for several years working on the distributed computing project, where he both acted as a co-investor and was involved into day-to-day software development management. He is one of the best in his field and is always willing to share best practices. His industry knowledge helped us to find more efficient way of software implementation, minimize expenses and improve the planning. He is also very responsible and detail-oriented, qualities that make him stand out. I loved working in the same project and I recommend to use services of his company.
