Full-stack Staff Engineer | Scaled telehealth & design-collab platforms | Love shipping fast, mentoring devs, and making systems reliable

United States
Message

I’m a Staff Software Engineer with 10+ years of experience building large-scale, high-availability systems and intuitive, user-focused applications. My background spans full-stack and distributed systems engineering across healthcare, SaaS, and AI-powered products — most recently at Amazon, where I led initiatives in real-time communication, workflow orchestration, and privacy-first AI for telehealth.

I’m passionate about designing clean, observable architectures that balance reliability, scalability, and developer velocity. Over my career, I’ve worked across Node.js, Java, Python, and TypeScript ecosystems, leading teams through service decomposition, API platform design, and end-to-end feature delivery in production.

I care deeply about user experience and developer experience — from optimizing clinical chat latency by 25%, to mentoring engineers on resilient system design and secure data handling. I thrive in collaborative, iterative environments where thoughtful engineering meets measurable product impact.
