Jeff Roush

Software engineer with seven years of experience developing a large Ruby on Rails/Javascript application seeking a full-stack developer position

General

Test-driven development in Ruby on Rails and Javascript using Vim, Git, and Bash in Tmux.
Built features. Fixed bugs. Wrangled deploys and Git branches. Wrote gems. Wrote ad-hoc scripts. Spelunked logs.
Managed Jenkins, Capistrano scripts, and Webistrano configuration.

Upgrades

Co-managed upgrades of the site from Rails 2 to 3.2, and from Ruby 1.8 to Ruby 2, and almost to Rails 4.
Wrote code to handle character set encoding as part of the upgrade to Ruby 2. We had thousands of MySQL customer databases containing text in many character sets stored in tables labeled as latin1.

Bug Fixes

Fixed data using the Rails and MySQL consoles. Tracked down bugs using Airbrake, NewRelic, logs, and the code.

Deploys

Deployed code updates and schema migrations across ten app servers and 6,000 customer databases. Collected updates, coordinated releases with developers and management. Wrote release notes. Debugged failed deploys. Updated Capistrano scripts as the server environment changed and as the application code was updated.

Docker

Dockerized part of the StreamSend environment for development. Updated Docker configuration for several components.

Wrote framework in Ruby for parallelizing our QA tasks with Capybara in Ruby. Browser- based tests run on three servers, with 8 browser instances on each server, against the application running on three QA app servers. Tests are managed by Jenkins as a Continuous Integration system; a subset of the
QA tests run after each merge request is created in Gitlab. The full QA suite runs nightly with four different configurations.
I wrote the base set of tests, to get us from scratch to having good coverage of the system’s features. Subsequent tests were written by developers as they developed features.

Keyboard, 2008-present

Built unique ergonomic USB keyboard using stretchable conductive fabric and 3D-printed plastic.
This is the keyboard that allows me to work.
Designed and hand-built the keyboard.
Wrote v1.0 USB firmware in embedded C.
Etched and soldered circuit board.
Built CNC router to cut foam.
Wrote scripts in Java to generate CNC G-code.
Designed plastic parts with OpenSCAD; printed with 3D printer.

MouseTool, 1997-2006

Designed and wrote software that clicks the mouse for you.
Sold MouseTool as shareware, then in 2002 partnered with Designer Appliances, maker of an innovative ergonomic mouse.
Used C++ for Windows and Linux versions.
Successfully lobbied for MouseTool to be adopted as part of KDE’s standard accessibility tools.
Ported MouseTool to OS X using Objective C.
Also developed Windows-based stretch timer in Python.

SacSOS

Set up server for Rails resource to provide information for Sacramento’s homeless population.
Reused code written for San Mateo by a Code 4 America brigade.
Fixed bugs. Updated the system for Sacramento.
Configured PostgreSQL and Nginx and currently host the site in an Ubuntu instance on DigitalOcean.
Dockerized the system for development.

git-commit-story

Ruby gem. Provides a “git commit-story” command that appends a Pivotal Tracker Story ID to each git commit message.

KMouseTool

Open Source version of MouseTool, ported to Linux using QT. It is now part of KDE’s standard accessibility utilities.
