Rails + Javascript (inc. AJAX) App: Pre-launch code and security review + advice for future maintenance

Budget $250 - $750 USD

Average Bid $543

I've spent the last few months building a Rails app that helps students preparing for job interviews to practise with each other. I hope to launch it in the next week or so, and have a promotional strategy in place that should guarantee a lot of users almost immediately.

As this is the first time i've launched a site of this scale, I'm now looking for an experienced Rails developer to take the code the final 5% to get it ready for launch, but also meet me in person in London for a couple of hours to advise me on what I need to know about maintaining the site (and it's database) once its online. Ideally you would also have a strong competence in javascript and how it sits in the Rails asset pipeline, as the site is javascript heavy inc. pure javascript, jquery, jquery-ui, google maps, AJAX, and the chart library AMCharts.

The app itself is not that large, with 4 models and controllers containing the bulk, with the majority of functions being the usual RESTFUL actions that you would expect on a user driven app. One of these is a notification system that sends emails to users for various events.

- Meeting me in London in the next few days so I can take you through everything in person.
- Predicting and patching security holes: could be e.g. checking model validations are sufficient, or preventing against double submission of AJAX forms.
- Predicting and overcoming any issues that might arise from scale
- Predicting and overcoming anything else to ensure the site functions successfully once launched
- ...and then a final meeting in London to advise me on what I need to know to maintain the site once its launched on Heroku going forward.

The work may also involve:
- Refactoring the Ruby (although hopefully this has already been done sufficiently)
- Organising the javascript in the asset pipeline (i've had a few problems with this)
- Tweaking the capybara test suite

Outsourcing this work has been planned and budgeted for from the start of the project - I've written the code with it in mind, being careful to make it self documenting, commenting where necessary, and strictly maintaining correct MVC organisation. You will not be ploughing through a total mess.

    I have a 5+ year experience in the IT field, mainly focusing on the web technologies stack. Throughout the years, I have actively participated in all phases typical software projects go through: requirements gathering, planning, scheduling, implementing, testing, deploying, releasing, etc. My strongest areas are PHP and MySQL, but I have vast experience with Javascript and RoR. I have worked mainly on high performance sites and my interest lies in projects, which require high and low level optimizations. I am also fluent in the Linux administration field and can handle simple sys admin tasks.
