At Visa, I own end-to-end delivery of Value Calculator and VAS Sales Navigator, B2B fintech applications used across five regions. I built pricing and fee-calculation interfaces that reduced calculation errors by about 44% and made quotes 2.5 times faster.
I also built a shared React and TypeScript design system, adopted by five Visa teams, and migrated Value Calculator to Angular 21 while product delivery continued. The migration cut render time by two seconds and reduced the bug rate by about 40%.
Before Visa, I owned Operative’s Product Chooser from technical design through launch and worked on payments integrations for Dena Bank’s merchant application at Tata Consultancy Services. I’ve also built document-workflow interfaces and procurement forms, and I mentor developers and lead frontend delivery.
