Built complete authentication systems, real-time SSE streaming, payment integrations, and complex UI systems including a custom drag-and-drop CMS page builder.

MBA background informs a product mindset: building systems that solve real business problems, not just working code. Security-conscious — responded to critical CVEs in production.
