Hi, I'm Chris. I've worked on many kinds of projects:

- high level things like web service, application, apis...

- low level things like Kafka, database, network, thread modeling... And I have some successful projects with both types. Here are them:

- Kafka gateway: Led development of the Conduktor Gateway (Kafka proxy) from scratch, build a successful product, got a lot of client and make this company become famous (https://docs.conduktor.io/gateway).

- Arcturus Project: https://engineering.tiki.vn/arcturus-inventory- processing-system/ Built a stock management service handling 5,000 transactions per second, resolving Tiki’s hot deal scalability issue and improving success rates by 40%.

- Developed a Java client for an in-memory distributed database (VIMDB), achieving 600,000 transactions per second with 1ms latency and 99.99% of requests under 3ms.
