    What people are saying

    Alan Company, BCN Visuals

    “I have had the pleasure of working with Jaakko on dozens of projects and have been consistently impressed by his talent and professionalism. His ability to create rich, detailed environments that are not only visually stunning but also realistic and believable is truly impressive (both in render and real-time software). He is able to take vague ideas and turn them into beautifully crafted 3D world. In addition to being a talented CG environment artist, Jaakko is also a joy to work with. His positive attitude and willingness to go the extra mile to ensure that the project is a success are just a few of the reasons why I would highly recommend him. Plus great team player! (Hard to find in today’s digital world)”

    Jesse van Blokland, JVB.Design

    "Took a 4 week training course for learning UE5 and the work flow needed for it as well as some additional training on software for said workflows. He provided great value of training and knowledge that let me succeed in learning UE5 but has allowed me to get up and running in UE5 in a very timely manner. Not only that he has many years in the technical artist field giving him the ability to provide training and wisdom on what’s expected for clients and what to expect and anticipate from the industry as a whole. I would recommend him for the creative and highly professional work he produces as well as the quality training he can provide as well."
