About

I’m a web developer and engineer manager, especially good at server side engineering.
I also like the technology itself, but I like the job of assembling customer’s tasks into concrete system requirements and I’m good at it.
I have plenty of knowledge on fintech.

And I’m a backpacker. I love all south east asian countries!
