What I'm looking for

I seek remote roles focused on frontend architecture and scalable React UIs where I can drive performance, architect design systems, and integrate AI to enhance product workflows.

I am a Senior Software Engineer with a Master's in Computer Science from the University of Florida and over 10 years of full-stack experience focused on frontend architecture and product-led growth. I progressed from building high-traffic gaming and staffing platforms to architecting enterprise-scale SaaS and collaborative tools while working remotely since 2020.

At Aha! I developed the real-time collaborative engine for Whiteboards, led frontend architecture for a Knowledge base module, integrated OpenAI workflows, and reduced global CSS bundle size by 40% through a Tailwind migration. At ServiceNow I modernized Employee Center UI components, built low-code visual builders, migrated ITSM dashboards to React, and engineered Node.js middleware for high-volume data ingestion.

I bring deep expertise scaling React-based UIs, managing complex state in distributed systems, and a backend foundation in Node.js and Ruby on Rails. I focus on performance optimization, developer-friendly design systems, and integrating AI to automate product workflows.
