I'm Matthew Sims, a software engineer with a long-standing passion for building and testing software. My career began in BT Research and Development in cybersecurity, where I advised on product and system designs, wrote software to test cryptographic algorithms, and contributed to patents. Alongside engineering, I spent many years in education as a mathematics teacher and leader, which sharpened my communication and project-management skills. Throughout, I stayed hands-on with software—from early 8-bit microcontrollers to modern Swift-based app development—and even started a software company. I am now seeking a full-time role designing and developing software.
