BSc Machine Learning student · Anglia Ruskin University, Cambridge

About

I'm a Machine Learning student at Anglia Ruskin University in Cambridge. I've always been the family tech support, especially for my dad, and that's what got me into this. I went from taking apart old laptops to programming, because I wanted to see how software actually talks to the hardware.

Summer of 2026 I was a software engineering intern at Clear-Com. In October I found a bug in Arm's MCP server, and Arm merged my fix.

Arm MCP Server: open-source fix

October 2026 · merged into arm/mcp

Found that the mca tool in Arm's MCP server passed the wrong flag to llvm-mca, so one of its options had never worked. Fixed it, added a regression test, and Arm merged it into main.

June – September 2026 · Clear-Com internship

Added tracing to an AI feature that configures intercom systems by chat, so developers could see every tool call's inputs, cost and time. Found three places where the system said "success" without doing the work.
