Nearly 20 years of turning new technology into things people use.
I'm Mate Marschalko, a creative technologist and lead engineer, and Web on Devices is my studio. I've built products used by millions for media, finance, travel and retail companies, and experiments that found an audience of their own. Every project gets the same senior engineering, whether it ships to millions of browsers or to a single sensor in a field.

“Mate delivered top-quality work from day one, guiding and inspiring the team toward coding best practices, testing, and pixel-perfect execution. He collaborated seamlessly with our manufacturing partners in China on low-level firmware challenges. The quality of his work positioned PA strongly with the end client. Mate excelled in client communications, handling presentations and demos with clarity and confidence. More than just a strong engineer, he consistently aligned with business goals, demonstrated exceptional planning and time management, and was always ready to step up and lead.”
“One of the best developers I have had the pleasure to work with. Pixel perfect in nature, the quality of what he delivers is second to none.”
“His blend of technical expertise and creativity meant he’d always deliver more than expected, to a higher quality than expected, faster than expected.”
“Mate joined us to help develop an experimental AI solution, and he quickly and efficiently led us through complex challenges. His expertise and innovative mindset truly made him a pleasure to work with.”
“Mate consistently demonstrated exceptional technical expertise and strong leadership skills. His capabilities impressed me so much that I invited him to join a project I was leading, and he delivered outstanding results.”
“Mate applies his wealth of deep technical knowledge to development challenges and produces innovative approaches to solving problems.”
“Having worked with Mate on a number of complex AI and tech related projects, he has always been very professional, knowledgeable in a very complex and ever changing market, and has always offered us value for money, been on schedule and on budget.”
Practical technology for a more interesting world.
I combine engineering, creativity and emerging technologies to solve real problems and create new possibilities. One pair of hands, from the circuit board to the cloud.
