What I'm looking for

I’m seeking a senior full-stack role building scalable, data-driven web platforms with modern JavaScript and cloud tech, where I can lead, mentor, and deliver high-performance, real-time user experiences.

I am a senior software engineer with over 10 years' experience specializing in modern JavaScript frameworks and full-stack development, delivering scalable, high-performance solutions across ERP, healthcare, finance, HR, e-commerce, and inventory management. I focus on system architecture, technical leadership, clean, maintainable code, and fast-paced execution.

I have built enterprise-grade platforms with React, Vue, Node.js and cloud services (AWS, Azure, GCP), engineered real-time features (WebSockets, WebRTC) and HIPAA-compliant video streaming, and optimized systems for millions of users. Notable contributions include Peerspace, Wealthfront, and Doxy.me where I led frontend refinements, serverless architectures, payment and communication integrations, and end-to-end testing. I am committed to mentorship, documentation, and designing reusable components that improve performance and maintainability.
