That would be me – Duong. Worked as a CDN Systems Development Engineer for VNG Corporation.
It is a good work, but I am always seeking for greater opportunities abroad, especially in Thailand, which is a place I wish to visit at least once a year.
Please have a look at my CV and contact me if you are interested in me and your business culture is conducive to young individuals that like flexibility.

Research and construct CDN components for VNG Cloud.
Optimize the traffic coordination system for VNG Cloud's CDN service, so that it can handle traffic up to 2Tbps during peak hours.
Optimize the log processing mechanism for CDN's edge servers. Provide clients with near-real-time access to live stats.
Without impacting customers, my system automatically distributes traffic to third-party CDN providers such as Akamai and AWS when VNG Cloud's traffic approaches its threshold.
My motto is "No Human - No Error", everything can be done automatically, without the need for human intervention, reducing the possibility of human-caused mistakes.
Learning and comprehending new technologies in order to optimize the CDN system.

Product vCDN & CDN ecosystems, Technical Lead
- Media Services: My team and I developed corresponding service cores for VNG Cloud, vEncoder, based on ideas from AWS MediaConvert.
- Authoritative DNS: The system that takes an address, such as google.com, and returns information about the resources (such as IP addresses) in that zone is known as authoritative DNS. A typical transaction would look like this: A user enters an address into a web browser, or an application calls out to a given name of an Internet resource. This core service for VNG Cloud was developed by my team and me.
