Message

At Visa, I was the sole technical owner of Visa Transaction Controls, a payments platform serving 100+ financial institution clients. I simplified configuration workflows to reduce client onboarding time by 50%, and integrated GPT-powered merchant category recommendations that cut manual review and setup time by 80%.

I also migrated the React UI and .NET Core proxy layer to Kubernetes-orchestrated Docker containers, reducing new-market infrastructure setup from three months to two weeks. By introducing an agentic AI development pipeline into CI/CD, I cut release cycle time by 50%.

Earlier at Visa, I contributed to digital banking and servicing platforms, including REST API microservices and a release validation platform. Across roles in banking, travel technology, and telecommunications, I’ve developed .NET applications and supported production systems, testing, and integrations.
