With over a decade of experience as a software developer, I am an ambitious, professional, and honest individual committed to pursuing quality and getting things right the first time. While my background is rooted in Java and Kotlin, I am ready to work with any technology that best fits the problem at hand. Having worked mostly at startups, I am accustomed to wearing many hats and thrive in dynamic environments. As a product-focused developer, I prioritize user feedback above all else to drive meaningful improvements. I am also skilled in hiring, building, and managing teams, serving as a leader and mentor to help others grow.
