Senior Technical Data Analyst
OSB Group
Benjamin Howell came to finance with a background in data and a willingness to tackle complicated problems. At OSB Group, that has meant everything from finding new migration dates for around 55,000 accounts in five days to building a prototype that helped his team win a hackathon.

"I came into financial services deliberately, through data."
The data behind the move
Benjamin's story so far...
Benjamin Howell chose financial services because he wanted to put his data skills to work in one industry. After degrees in international economics and data science at Loughborough University, he moved to Prague in 2022 to work in technical consultancy. Three years later, he returned to the UK and joined OSB Group.
One of his first big challenges involved deciding when roughly 110,000 online savings customers, holding around £5 billion, would move to a new banking platform. Four migration weekends were planned. Then the first was cancelled with one day's notice, leaving around 55,000 accounts needing new dates.
Benjamin had five days to rework the allocation. Linked accounts had to stay together, and fixed rate maturities could not fall too close to a move. He rebuilt the process, checked the customer, account and balance totals, and secured approval for the revised approach. Every affected account was reassigned, and the remaining weekends went ahead without allocation errors.
He has also enjoyed exploring what the data could make possible for customers. Leading a hackathon team, he built a working prototype of a Savings Hub that brought savings goals together in one app screen. The team won local and international rounds. Benjamin is now developing his cloud and AI knowledge while mentoring students and encouraging more people to consider the technical careers available in finance.
