Summary
👤
Senior🎓
Top SchoolCalvin Nguyen is a versatile Customer Engineer at Google with 10 years of hands-on experience building full-stack systems and taking products from prototype to production, particularly in backend services using Node.js, Go, and Java. He’s worked across startups and large enterprises—first engineer at IMI.AI and mobile/backend roles at PayPal—bringing practical experience in payment integrations, mPOS devices, and cloud-native deployments on GCP and AWS. Comfortable across databases (MongoDB, PostgreSQL), front-end React/Cordova, and mobile Swift, he pairs deep technical breadth with customer-facing technical advisory for growth and health-tech companies. Calvin is also learning gRPC and AI tooling (Python, TensorFlow, OpenCV), and shares technical writing and projects publicly via Medium and GitHub, reflecting a habit of documenting hard-won engineering lessons. Not obvious from titles: he has repeatedly accelerated testing and integration velocity (3x iOS testing improvement at PayPal) and thrives at the intersection of product prototyping and scalable production delivery.
