I have a proven track record in managing engineering teams and developing scalable web applications in fast-paced environments. My experience spans from creating advanced web performance analytics platforms to leading the engineering department of a successful online marketplace. Recently, I spearheaded a project to design and build a comprehensive payments and taxes platform, handling millions in transactions and integrating multiple PSPs, for one of the largest global micro-mobility operators.
