What I'm looking for

I seek senior architecture or platform roles where I can shape cloud-native strategy, improve security and CI/CD practices, and foster cross-team collaboration and developer enablement.

I am a software architect with a strong track record of driving architecture strategy and delivering cloud-native solutions for large-scale financial products. At Vanguard I led architecture governance, piloted CI/CD practices, and modernized critical systems to improve production quality and delivery speed.

I have hands-on experience building client-facing dashboards and event-driven microservices using AWS, NodeJS, Angular, and Java, and I led initiatives that modernized monolithic platforms into real-time, service-oriented systems.

I focus on security-first architecture and developer enablement — directing security architecture and adopting identity platforms like Okta, Auth0, Kong, Envoy, and OPA, while launching mentorship and InnerSource programs to scale cross-team collaboration.

My work emphasizes measurable outcomes: improved DORA metrics, rapid onboarding via shared tooling and training, and increased reuse and maintainability through enterprise libraries, tech radars, and governance.
