United StatesWhat I'm looking for
I am a senior software engineer with 10 years of experience designing and shipping AI-powered products at large-scale consumer companies. I specialize in full-stack development using React, Node.js, Java, and Python to deliver performant, production systems.
At Walmart I contributed to e-commerce systems that supported 120 million monthly users, built conversational shopping UIs, and orchestrated Node.js services that integrated Python NLP models to deliver sub-200ms query responses for a 150M-item catalog.
Previously, I developed telehealth scheduling platforms at Teladoc using React, Java Spring Boot, PostgreSQL and Azure, migrated monoliths to microservices with Docker, Kubernetes and Kafka, and improved reliability and appointment success through resilient scheduling logic and integrations.
Earlier work at Dropbox focused on high-performance distributed backend components in Python and Ruby on Rails that improved sharing efficiency and supported millions of daily events; I mentor engineers, lead design reviews, and document architectures for cross-team reuse.
