CrestCo Ltd, now Euroclear UK & International (EUI)

CrestCo Ltd, now operating as Euroclear UK & International (EUI), is the central securities depository (CSD) for the United Kingdom and Ireland, responsible for the electronic settlement of securities transactions.

Founded in the mid-1990s, CrestCo revolutionized London’s financial markets by moving them from paper-based share certificates to a “dematerialised” (electronic) system, thereby significantly reducing settlement times, risks, and costs.

Welcome to my site! After graduating in Computing in 1990, I accepted a position as a programmer at a Runcorn based software house specialising in electronic banking software, namely sp/ARCHITECT-BANK on Tandem Computers (now HPE NonStop). This was before the internet became more prevalent and so the notion of enabling desktop access to company accounts for inter-account transfers and book keeping was still quite a cutting edge idea (and smartphones only ever hinted at in Space 1999). The company was called The Software Partnership (which was taken over by Deluxe Data in 1994). I spent 5 years in Runcorn developing code for SP/ARCHITECT for various banks like TSB, Bank of Scotland, Rabobank and Girofon (Denmark) to name but a few. I then moved onto a software house in Salford Quays for further bank facing projects. After a further 23 years in the IT industry and now a Senior IT Project Manager (both Agile and Waterfall delivery), I thought I would echo out my Career Profile in this corner of the internet for quick and easy access.
