Stan Lo（st0012）
I'm a Ruby/Rails developer who loves to contribute open source projects. I have contributed some popular gems like Rails, formtastic or html-pipeline...etc. I am also the creator of goby language, which is a Ruby-like object-oriented language written in Go.
Programming is not just a skill for me, it's also my dominant interest. And my dream is to work with a bunch of smart people on a product I'll be proud with.

Full time language designer, 26 May 2017 - 31 August 2017
In these three months I focused on my Goby language project in full-time. I worked with contributors from all over the world. There were contributors from Poland, Japan, Germany and many other countries. And we finished, released Goby's first official version together.
We all worked remotely and crossed different timezone. This is a very valuable experience for me, and also proved that I can work remotely in a distributed team without communication/time difference barrier.

Skills
Ruby
I think I already have certain experiences in Ruby and have contributed over 20 Ruby gems. Besides writing Ruby, I also understand how it works (mostly), goby's VM is basically a simplified YARV.
Rails
Despite of writing Rails app during my work, I am also quite active in Rails community. I've implemented a few features in Rails, like ActionMailer's fragment cache in Rails 5.0. And occasionally discussing in Rails issues.
AWS
I can say that I'm familiar with ECS because I was in charge of dockerizing all of our Rails apps and migrating them from OpsWorks to ECS. I also know how to provision instances with OpsWorks or setup ELB...etc.
Testing Frameworks
I use RSpec everyday at work and when writing my own gems. I also learned how to use minitest when contributing Rails and other projects that don't use RSpec.
Go
I write Goby in Go so I think I can say that I know how to write Go. But I have to admit I haven't wrote any production project's in Go. I just use it very frequently after my work.
Projects
SafeFinder
SafeFinder lets you define a model's Null Object through a simple DSL, and returns that when you don't find an instance of that model.
Goby
(previous named Rooby)
An object oriented language inspired by Ruby and written in Golang, which aims at developing microservice efficiently.
Contributions
Rails (commits)
- Cache ActionMailer's view templates (Released in 5.0)
- Better logging for cached partial rendering (Released 5.1)

Other projects
- Formtastic: Improve timezone input
