Hi, I'm Hanzhe Li

I'm a Software Development Engineer II at Amazon Web Services in New York City, where I lead full-stack development and architecture initiatives. With over 4 years of hands-on experience with AWS services including DynamoDB, Lambda, OpenSearch, and CloudFormation, I specialize in building scalable, high-performance solutions for complex technical challenges.

My journey in software engineering spans from my Bachelor's degree at Wuhan University, through visiting studies at UC Berkeley, to earning my Master's in Computer Engineering from NYU. Since joining AWS, I've led critical projects including redesigning core search systems, resolving launch-blocking authentication issues, and achieving 0→95% backend test coverage on production systems.

I'm passionate about performance optimization, cloud architecture, and engineering excellence. Recent achievements include enabling Python 3.10 migration across 20+ repositories, saving $20k+ monthly through operational optimization, and delivering compliance solutions under tight regulatory deadlines. I thrive on solving challenging technical problems that deliver measurable business impact.

Beyond software engineering, I'm a serious wine collector with a focus on Burgundy and Champagne. My collection spans a few hundreds of bottles including Grand Cru treasures from Montrachet, extensive Champagne verticals (Krug, Dom Pérignon, Salon), and world-class producers like Coche-Dury, Ramonet, and Giacomo Conterno. Over the past two years, I've consumed nearly 400 bottles averaging 11-year vintages, with 80% white wine—a testament to my belief that great Chardonnay represents the ultimate expression of terroir. I actively explore emerging regions including Japanese sake and German wines, building a cellar designed for decades of maturation.
