Technical. Innovative. Versatile.
I'm a software engineer pursuing a BEng in Software Engineering at the University of Southampton, driven by a passion for building impactful digital solutions.
My approach combines rigorous technical standards with creative problem-solving. From architecting high-performance trading simulators to developing AI-driven interview platforms, I focus on delivering measurable results.
Outside university, I have gained international experience, working as an intern in Brunei and London, collaborating with teams from diverse cultural backgrounds. This has strengthened my ability to work effectively in multicultural environments, beyond just coding.
