I'm a Systems Engineer with 4 years of experience at Infosys, where I channel my curiosity and drive for mastery into building reliable, well-reasoned technical solutions — most recently centered around REST APIs. I thrive in collaborative environments where logic and idealism intersect, allowing me to pursue not just what works today, but what scales and endures. Flexible in my approach yet grounded in analytical thinking, I enjoy working across teams to turn complex problems into clean, purposeful systems.
