About

I'm a backend focused full-stack engineer with 6 years of experience, currently working at Deliveroo with a strong focus on backend development. I specialise in building scalable, high-performance systems with deep expertise in Go, Python, AWS, messaging queues (like Kafka), big data platforms, and modern web frameworks such as Next.js and React. I'm particularly passionate about designing systems that handle real-world scale and complexity. Whether it's architecting distributed applications, optimising backend performance, or automating cloud infrastructure, I enjoy solving challenging engineering problems and delivering practical, impactful solutions. I'm also deeply interested in AI and large language models (LLMs), and I enjoy exploring how they can be leveraged to automate workflows, enhance productivity, and build smarter systems. Always eager to learn, collaborate, and contribute to systems that make a meaningful difference.
