An engineer with
an eye for detail.
↗MSc Software EngineeringKingston University LondonMerit · 2024–2025
I bring 5+ years of experience across fintech and B2C products, backed by an MSc in Software Engineering from Kingston University London. I enjoy owning the frontend journey: understanding the problem, shaping reusable components, integrating APIs, reviewing code, and getting reliable features into production.
My focus is on the details that make a product work well: accessible interactions, predictable state, consistent design systems, and thoughtful performance improvements.
Away from the keyboard: music, football, travelling, and video games.
