My role combines deep technical focus with strategic oversight and I'm fortunate that HSO gives me the freedom and tools to keep evolving.
With over two decades of experience in the data space, George Vourdanos, Principal Data Architect at HSO, is no stranger to designing robust, intelligent solutions. Based in Swindon, George has spent the past two years at HSO shaping enterprise-grade data platforms using Azure, Power BI, and the latest Microsoft technologies, including Fabric.
In his role, George leads the architectural design of data solutions across multiple projects, while staying hands-on with code and delivery. “It’s a role that combines deep technical focus with strategic oversight,” he explains. “And HSO gives me the freedom and tools to keep evolving.”

It’s a friendly, flexible environment, where the professionalism is matched by a strong sense of camaraderie. Compared to other Microsoft Gold Partners I’ve worked with, HSO feels more human, more connected.

One project highlight has been leading the Valeo Foods data platform delivery, working closely with the team to bring structure, insight, and scalability to the client's data strategy.
With the rollout of Microsoft Copilot and AI tools across the business, George is already seeing productivity gains. “Using Copilot in Paint, Word, and PowerPoint has sped up everything from documentation to architectural design. It’s been a great enabler.”

From India to Silicon Valley, and from Malta to Rotterdam: Siddharth and Divya Singh have lived all over the world and worked for the same employers. Together with their daughter, they have seen it all. How did the couple end up at HSO in the Netherlands? In this interview, they share their remarkable story.





For many years, HSO has been recognised for its deep expertise in business applications and its ability to deliver complex, mission-critical solutions for customers across industries. That foundation remains central to who we are. However, the needs of our clients are evolving, as are we.










Expats bring fresh ideas and new energy. But they also face challenges. A new country, a different culture, unfamiliar work habits – and on top of that, building a social life. To exchange experiences and build connections, an expat community was created. Not a formal club, but a space where international colleagues can meet – over lunch, at a drinks event or just for a good conversation. We spoke with three of them about their experience: what was it like arriving in the Netherlands? What stands out in the work culture here? And what does it mean to be part of this community?

"Not your diploma, but your drive. Not your experience, but your curiosity." That seems unthinkable – but not at HSO. "With the right basic attitude, anyone can get started here," says Henk-Jan Brommer, manager of HSO Academy. It sounds ambitious, but practice shows that it works.

Professional development begins with collaboration. The biggest steps are taken when we combine our knowledge and talents. Take Albert Hol (Project Manager) and Gerben Mulder (Consultant Management). They worked together on a project for a large retailer, where the billing process was renewed within Dynamics Finance & Operations using Azure Functions. The solution enables the retailer to process and invoice about 150,000 order lines quickly and accurately every day.

HSO has grown rapidly in recent years. This brings change, including in the company culture. To preserve the core of the old culture and embrace new values, a core group has developed a culture compass. Two members of the core group, Behnud and Otto, share their insights.
