Crafting Experiences
at Scale

I'm a Staff Software Engineer with over 9 years of experience building scalable, user-first web applications. At VISA Inc, I lead development on payment flow products that process millions of cross-border transactions daily — including Visa Direct and Visa Payments Limited. I'm passionate about leveraging new technologies, including AI and generative tools, to create impactful software that makes a real difference. I believe great engineering is equal parts craft, empathy, and relentless attention to detail.
