Spencer Attridge

Migration Expert

Biography

I began my career in the British Army as a Radio Telegraphist with the Royal Signals before transitioning into the Private Banking Sector in the UK.

While advancing in the Investment Department, having roles in multiple areas in the office, I taught myself to code, which eventually led me to lead my first migration of a banking system in 2003. With this experience I decided to pivot again, focusing on Migration and have since worked as a migration specialist on numerous UK and international Avaloq projects, helping streamline banking systems globally.

In recent years, I’ve had the opportunity to work with our A.dapt product. It’s been an eye-opening experience, seeing it implemented and contributing to its development, client side.

Interests

Outside of work, I engage in what’s known in the UK as a ‘busman’s holiday,’ where I migrate genealogical data into graph databases to construct family trees. I’m a proud member of the Guild of One Name Studies, where I tackle the challenges of wrangling historical data. My passion here is the untidiness of data and I enjoy the challenge of wrangling the data and solving the problems inherent in historically collected data.

To that end, I took a Fast.ai course some years ago and with the increase in LLM’s and tools such as Codex, I’ve been excited to incorporate them into my work, the pace of change in AI and LLMs is remarkable, and I actively keep up with the latest advancements, always looking for ways to integrate these technologies into my work. I have a particular passion for Golang with Text User Interfaces and Jupyter Notebooks for Data Analysis and it’s fun to see what LLM’s can do to help with it all.

Outside the tech world, I balance my time with my lifelong passion for Chinese martial arts, ensuring I stay connected to both mental and physical well-being.
