What I'm looking for

I'm looking to build scalable, reliable web applications and data-driven workflows with React, TypeScript, and Node.js while collaborating closely with product, design, and engineering teams.

At Discover Financial Services, I redesigned core workflows for an internal analytics platform, cutting page load times by 25% and user-reported errors by 20%. I led front-end development and architecture planning for a React and TypeScript platform used daily to design, configure, and manage enterprise data pipelines.

I've also built scalable backend systems, replacing a monolithic e-commerce API with microservices using Node.js, Express, PostgreSQL, and MongoDB. My Atelier API microservice sustained 1,000 requests per second with a 1ms average response time, while load balancing with NGINX and AWS EC2 reached 5,000 requests per second at 3ms.
