I am a software engineer with over a decade of combined experience in application support and development, recently focusing on modern software engineering with Java, React.js, and Python. My career has given me strong exposure to Agile environments, and I have developed, supported, and improved live software applications in cloud-hosted systems, often with minimal supervision. I thrive in early-stage projects or technical roles where I can contribute to design decisions and problem-solving at the conceptual level. While I have held SC and previously DV clearance and am fully comfortable in secure environments, I am now looking to move beyond the defence sector. I want to broaden my exposure to modern technologies and design-led software roles. I am especially drawn to collaborative teams working on scalable systems and meaningful user-facing features, and I welcome opportunities that align with those values.
