I've architected and modernized web applications for Emeritus, Dell EMC, Tecsys, Akamai, CGI, and IBM across product development, IoT, supply chain, and financial securities.

I also built a multi-tenant SaaS platform for AI-based learning features and led video-player enhancements for analytics, bookmarks, playlists, and themes.
At Dell EMC, I led technical delivery for device onboarding and connectivity microservices, improved device-registration session handling by 50%, and introduced distributed tracing and code-review standards. At Tecsys, I delivered the first multi-tenant SaaS Workday integration using event-driven AWS architecture and improved IoT device page rendering by 70%.
I focus on performance, scalability, security, observability, logging, and application performance monitoring, using Java, JavaScript, TypeScript, Python, cloud platforms, and AI tooling to deliver reliable software.
