serve2perform is a legacy Rails application sitting at 3-2-stable and was built over a fair amount of time by several independent contributors. It includes approximately 100 common gems and uses no frontend frameworks. All frontend work is done with vanilla JavaScript and ERuby for templating. Most of the code is standard CRUD work without any crazy tricks, metaprogramming, or other oddities. The application is deployed on a single VPS at the moment but was formerly hosted with Heroku. Work was done in late 2019 to upgrade the codebase to Rails 4.2. Since that time, the codebase has diverged by around 130 or so commits of varying size. The upgraded codebase is sitting in its own (functional but outdated) branch. It needs to be merged with the changes in the master branch and it needs to be brought to a deployable state. Where possible, the codebase should also be prepped for upgrading to Rails 5+ by identifying any major points of change and following newer standards. Finally, we do not wish to introduce any modern niceties at this time (patterns, frameworks, libraries, etc). This work is strictly focused on combining branches, reaching a deployable state, and (if possible) preparing code for future upgrades. Skills needed: - Strong comprehension of Rails 3 and 4 - Strong comprehension of popular libraries from the Rails 3 era - Insight into Rails 5 - Strong comprehension of git - Fair understanding of Redis and Resque - Fair understanding of PostgreSQL - Vanilla JavaScript competency - ERuby, HTML, SASS, and CSS competency - A demonstration of clean coding and documentation practices

Dear Hiring Manager, I have been working in rails 3, 4, 5 and 6. I do have a hands-on experience of upgrading ruby and rails version of many applications, with heroku and custom servers upgradations. I understand the issues we can face while doing the deployments and manging the code. The code needs to be backward compatible and we should take all precautions to take this diverted code to live application. We can discuss this in more detail, I look forward to speak to you in this regard. Sohair.
