Michael Jin

I’m a Staff Software Engineer with 10 years of experience building and scaling mission-critical systems across fintech, healthcare, and global commerce. I’m product-minded and thrive in ambiguous, high-stakes environments, where I own complex systems end-to-end and make thoughtful architectural decisions.

At Shopify, I led the development of Shopify Magic, delivering AI-powered, full-stack commerce features that enhance merchant productivity, content creation, and operational efficiency. I built and scaled backend services in Go and frontend experiences in React and Next.js, integrating AI-assisted workflows into high-traffic, merchant-facing surfaces through GraphQL/REST APIs and orchestration layers designed for safety and reliability.

I’ve also built healthcare platforms at Teladoc Health, delivering full-stack capabilities with Java (Spring Boot) and React, plus backend services in Python (Django, Flask) with REST APIs and WebSocket support for real-time patient-provider workflows. I contributed to data-driven and intelligence-assisted systems backed by PostgreSQL and DynamoDB, and helped scale on AWS with Docker and Kubernetes while meeting HIPAA and healthcare compliance requirements.

Earlier, at Robinhood, I built customer-facing trading systems supporting millions of users using Python (Django, FastAPI) and React with Redux, and I designed event-driven architectures with Kafka and WebSocket. Across roles, I’m known for strong ownership, cross-functional collaboration, observability with Datadog and Grafana, and mentoring engineers through design and code reviews—turning complex problems into reliable, scalable solutions.
