About Me

I'm a Senior Software Engineer at Rocket Lawyer with over two decades of experience designing and delivering enterprise-grade software. My career spans from hands-on development in Java, Python, and Kotlin to leading cross-functional engineering teams building microservice architectures on Kubernetes and cloud platforms.

I specialise in cloud-native architecture, CI/CD pipelines, and data-driven solutions. Recently I've been leading projects that leverage machine learning and LLM models to deliver intelligent recommendations and customer insights.

Beyond work, I contribute to open-source, mentor junior engineers, and write technical articles on Medium about Java internals, design patterns, and DevOps practices.
