Read articleAbout our IT blog
In this blog we share practical insights from over 15 years of software development: technical guides, experience reports from real projects, and assessments of current trends such as artificial intelligence, cloud migration, and legacy modernisation. We write for decision-makers looking for sound information for their IT strategy, as well as for developers who need concrete approaches.
Our articles grow out of our day-to-day work with clients: when we solve a problem that might be relevant to others, we document the solution here. When we evaluate a new technology, we share our honest assessment – including the points vendors prefer to gloss over. We avoid marketing speak and focus on what actually works.
Topics range from concrete programming guides and architecture decisions to strategic considerations on digital transformation. Use the category filters above to find articles that match your interests. If you have questions about an article or miss a topic: feel free to contact us – we welcome feedback and suggestions for new posts.
Alongside the blog you will find our IT glossary with over 100 explained terms, our video tutorials, and published books by our founder Björn Groenewold. Together these resources form a solid information base for anyone making informed IT decisions.
