Software Engineer · Amazon Alexa Shopping
Jolin Zhang
I build large-scale, customer-facing notification and shopping systems — from backend service design to the polish of the end experience.
ScrollAbout
Software engineer on Alexa Shopping at Amazon, focused on distributed systems that reach millions of customers.
I led a 9-person team to migrate Alexa's notification delivery off five legacy systems onto a single unified platform, brought Add to Delivery to Alexa devices, and shipped an ML-driven backoff mechanism that lifted notification read rate ~23% while keeping purchases flat.
I care about clean systems design, measurable customer impact, and shipping the last 10% of polish that most people skip.
