Bettha

一个在服务器端带有API的Ruby on Rails应用程序, 以及客户端的Angular和Bulma应用.

I've participated in every part of this project—which includes both sides of the application, 加上管理小组, 处理评估测试的辅助应用程序, and all the infrastructure setup for staging and production environments. I was able to conduct the creation of an SDK for the secondary application, work with queue tools, 设置AWS和Heroku环境, practice code reviews, follow pull requests, 并参与所有的架构决策.

Rails PostgreSQL GEM

http://github.com/crashtech/torque-postgresql
I've created this GEM to improve the methods and add new features to Rails Active Record using PostgreSQL. 一些简单的事情，如DISTINCT ON SQL命令, 转换为Relation方法, 以及其他更复杂的数据类型，比如组合数据类型.

PHP和OrientDB二进制连接

A PHP sample code that shows a base class that helps communicate and exchange data using the database's binary connector. Each operation that can be performed on the database extends this class and uses the available methods to be correctly performed.

This sample shows how I like to comment on code—keeping it perfectly standardized and organizing my classes. Although this was written in 2014, it's still an excellent example of my work.

LogiShift |二进制系统

http://www.binarysystem.eu/en/softrail/logishift
A huge RoR application, which handles an even bigger amount of data every day in an almost-live response time. This is an international work experience where I was able to put all my cutting-edge knowledge about Rails and PostgreSQL in practice—especially on tasks that I had to improve the performance so that the live graphs were able to load in a very short time. During this project, 我主要是创建新的功能和报告, 重写了一些遗留代码, 并在几个方面提高了性能.

Zolvia

A project that I've worked in the last year, built using RoR and Bootstrap. A good example of a simple website with an administrative panel and all sorts of tools that can be used in all kinds of projects.

4 Shot

A PHP application using Drupal and set up to be used as an eCommerce website to sell short-length courses online or face-to-face. I installed and put online the very first version of this website in 2014.

Rails GraphQL

http://github.com/virtualshield/rails-graphql
A fresh new implementation of a GraphQL server that relies on Rails resources and helpers, plus it uses a self-implemented query parser written using the C-side of Ruby. The gem includes several APIs and facilitators to translate Rails resources into GraphQL resources.
