If you've worked with OSS for any length of time, you'll know Andrew. He worked closely with Julian for years and was a constant presence across the business. For many clients, he was the go-to person - trusted, practical, and always on top of the detail.
Andrew played a big role in shaping how OSS operates today, from the way systems are designed to how issues get resolved. He was involved in more conversations, decisions, and day-to-day problem solving than most people realise.
After more than 20 years with OSS, Andrew Chean left the business in September. We miss having him around, and we wish him all the best for his future adventures.
With Andrew's departure, we're also pleased to share some well-earned promotions and a new addition to the team.
Peter Wright has been promoted to Operations and Technical Manager, stepping up from Senior Engineer. Peter has been with OSS for nearly 20 years, bringing deep technical experience and a clear understanding of how the business runs. It's a natural next step and one that gives continuity across our operations and technical teams.
Maciej Słeczcek has been promoted to Senior Engineer, recognising his experience and the consistently high standard of his work.
We also welcome Shance Troski, who has joined OSS as an Engineer, strengthening the team as we head into the new year.
