about
Who I am
I'm a senior software engineer with 9+ years of experience, specialising in backend systems, data pipelines and API integrations. I take ambiguous problems from R&D through architecture and requirements into production.
My strongest areas are Kotlin and the JVM, AWS, APIs and data pipelines. I use Claude Code and MCP day to day for R&D, unfamiliar codebases and incident investigation, and I check what it gives me against the code and the data before I act on it. Outside work I'm into motorsport and track days.

Career
Mar 2023 – Present
Joined as Backend Engineer and promoted to Senior Backend Engineer in July 2024. Regularly act as technical lead for the Analytics & Reporting team, a distributed team of 9, driving technical planning and delivery.
- Led the Apple Insights, Apple Business API, Meta Insights and Uberdocs work in Highlights, and own our metric deprecations, API migrations and the working relationship with Apple's API team.
- Took the two heaviest tickets in our Databricks driver migration, upgrading a service from Java 8 to Java 21 and then swapping the driver as a separate change. Finished six weeks before the retirement deadline with no rollback.
- As the only UK-based engineer on a team spanning the Americas and Dubai, provide early-day coverage for client-facing and system-critical issues.
- Review design documents for other teams, interview backend candidates and built the interview tracker the team uses to share interviews out.
- Act as the team's agile advocate: I run its ceremonies, wrote its Definition of Ready and Definition of Done, and hold us to both. I onboard new engineers and unblock teammates when they're stuck.

I design, build and look after websites for businesses across Yorkshire and the North East
Austin Tech Solutions is my web design business. I work with any kind of business or organisation across Yorkshire and the North East, on new websites, redesigns, SEO, hosting, ongoing maintenance and Google Business Profile management. It's one senior engineer rather than an agency, and it's built to be hands-off: you give me a brief and approve the work at a few points, and I handle the content, the launch, the hosting and everything after.
