Andrew is a Tech Principal at Thoughtworks, specializing in Java / JVM technologies, agile delivery, build tools and automation, and domain driven design. They have experience across the software development lifecycle and in many sectors.

Andrew is also an author and trainer for O’Reilly. They've written one book about facilitating software architecture and one chapter about implementing the Accelerate/DORA four key metrics. They also run regular online training sessions in Domain-Drive Design (First Steps) and Architecture Decision Making by Example.

What motivates Andrew is the humane delivery and sustainable evolution of large-scale software solutions, that fulfill complex user needs. They understand that people, architecture, process and tooling all have key roles to play in achieving this.

Andrew has a great passion for open source software and its communities. They have been involved with OSS to a greater or lesser extent since their career began; as a user, contributor, expert group member, or paid advocate - most notably as one of the Jenkins JobDSL originators.

Andrew enjoys sharing their experience as much as possible. This sharing is not only seen in their formal consulting engagements, but also informally through mentoring, blog posts, conferences (speaking and organising), and open-sourcing their code.
