Intro
What drives the way I build.
I work at the intersection of product clarity, clean architecture, and team velocity. The goal is always the same: deliver software that solves real problems and stays maintainable as complexity grows.
I am Nash de los Santos, a software developer based in Cardiff, Wales. I bring broad experience in software design, development, and system integration with a deep focus on scalable architecture and practical design patterns. My background includes building systems for banks and fintech companies, including Barclays, Crestbridge, and Apex Bank, where reliability, security, and precision matter most.
My stack includes Laravel, Symfony, PHP, MySQL, JavaScript, and Vue. I thrive in fast iteration cycles, collaborate effectively across multiple initiatives, and lead teams through complex delivery with high attention to detail.
