Changhai Y.

I graduated from top university in China, and have 15+ years of working experience on web development based on Java. In recent 3+ years, I worked in Vancouver Canada. Due to my work, I gained much hands on experience on AWS, including DynamoDB, Lambda, SNS, SQS, RDS, Amazon Connect, S3, etc. The system I designed can handle 10,000+ TPS. I also learned machine learning in my spare time. I had an US patent in data processing area (algorithm).
