Thomas Bonderup - Freelance IT Consultant / Software Engineer

Are you thinking of starting your own product or service based business at some point? Are you running an existing business that uses software and hardware? Or are you just tired of doing the same repetitive tasks over and over? If you need help, then maybe I can help you as an IT consultant.

Hi, I’m Thomas Bonderup. Starting or running a product or service based business is tough in today's competitive digital age with artificial intelligence and robots. It is especially a struggle, if you don’t have the necessary expertise in computer science to leverage computers at scale and to automate repetitive tasks. Learning to computer code yourself is possible today, but few people have the discipline to stare at the computer screen for hours writing complex computer code that can break anytime.

To get the benefits of it-consulting services, you often have to work across time-zones with remotely located it-firms that have cultural differences and language barriers, which makes communication difficult. Or you work with large it-firms that charge a high hourly rate, but here your project is often not of high priority, because their senior software engineers always seem to have bigger and more important client projects to work on, so you get matched up with more junior developers.

Since 2015, I have worked as a freelance it-consultant or software engineer helping businesses leverage computers at scale to gain insight and automate boring repetitive business workloads. I specialize in large-scale multi-cloud infrastructure for robots and internet of things (IoT). I design computer architectures across the stack doing both software (problem solving, algorithms, programming, operating systems) and hardware (ISA, microarchitecture, logic, circuits).

I have a Master of Science (Msc) in Computer Science and Informatics, and a Bachelor degree in Computer Science. I have taken 6 years worth of advanced technical courses such as artificial intelligence and deep learning, programming for security, theoretical computer science, including project management and software architecture related courses to also study the structure, behavior and interaction with complex computer systems. For my master thesis worked on a virtual power plant system for peak-shaving with electricity price forecasting and battery scheduling in the sector for energy and utilities. Today I build sustainable it-solutions at, which is a continuation of my work with my master thesis.

On the more personal level, I have a long background as an elite athlete, where I have played the team sport handball at the highest level for many years. Today, I use many of my competencies from the world of sports in my consulting work. I enjoy hiking and spending time in nature. I am passionate about programming with an interest in competitive programming. I like to work on both hardware and software to solve hard technical problems with Big Data and algorithms. I sometimes write blog posts on my blog.
