    Hello, thanks for your interest. I'd love to work on your project, however I'd like to set a few conditions if you hire me. If there is more than 1 dev on the team I insist on peer review and a version control system - I prefer git & github however I'm not opposed to bitbucket and gitlab. Even if I'm the only dev, we should probably use a version control system. I'm also a firm believer in writing tests so changes in one part of the code will not break other parts, it's saved my bacon several times. Testing is one reason why I love working with Flask, and angular.js looks very promising. I would love the opportunity to work on a project that uses angular.js. Even if you don't hire me please implement peer review. That way when you hire me in the future your team is already set up with good habits. Here are a few good articles on the importance of peer review. http://www.techrepublic.com/article/developers-guide-to-peer-reviews/ http://www.ibm.com/developerworks/rational/library/11-proven-practices-for-peer-review/ Now that I'm done with the peer review PSA (Public service announcement.) Allow me to brag about myself. Over the last 11 years I have taught myself how to program in PHP and Python. I entered my first Basic program into a computer when I was in 3rd grade. I love using jQuery to make a site pop. I run my own .com from home with a Linux server on site. This has given me much insight into how servers are maintained, and backed up. I have set up and maintained the following servers Postfix(email), Apache(http), Nginx(http), Open-ssh(ssh) and used Supervisor and Gunicorn to deploy python web apps. I'm also an avid listener to several podcasts, such as Security Now, Linux Action Show, Techsnap and Coder Radio just to name a few of my favorites. Due to the nature of the NDA (Non-disclosure agreement) I can not list what sites/companies I've worked for, I will however tell you what we've used, and a vague description of the work we've done. On a couple of different projects we've used basic google maps, twitter, and facebook api. Some other common js/css libraries are moment.js, bootstrap, and chosen jquery plugin. Most recently I've been doing backend work. This include python, Flask, Flask's restful api to build the backend for an iphone/android app as well as a web front end to administer the data. The iphone/android dev team created the app with Sencha which I deployed using an nginx server. I also helped develop booking software. This includes reports, calendar, artist/user profiles, timezone management, traveling, accommodations, fees, commissions, venues, repertoire and currency conversion. To date, this has been the most challenging and rewarding project for me. The team I work with are extremely talented. We used Python, Flask, Mako, MongoDB, jQuery, Backbone.js, Underscore.js and Java. With another project we parsed PDFs about [undisclosed] and put the information into a database that could then be searched through based on the information mentioned in the PDFs as well as attaching an expiration date to the information parsed. Other accomplishments include a picture labeling program for HUD home inspections that would insert images into a .doc file when needed. It used a lot of jQuery/ajax calls to assign a case number, address, city, state, zip, and classification with lots of auto-complete. The database was MySQL, and I used headless instance of OpenOffice/LebraOffice with a the pyuno bridge to generate the .doc files. I hosted/managed this site for several years, and developed it as new features were needed. I parsed PDF files to get case information, as well as cut out specific pages that needed to be printed, and sorted them out for specific agents. For another project we used a combination of MongoDB, SOLR, MySQL and CodeIgniter. At the time I left we were in a transitional stage converting the site from an affiliate e-commerce/auction model to an advertising model. This project started out using MongoDB and eventually migrated to MySQL. In my spare time I'm developing a Family Media Player https://github.com/the7erm/fmp-pg It uses pygtk to render it's gui, postgresql for it's database, and gstreamer to play the audio/video. I've been focusing my development efforts on creating a web frontend that utilizes Flask so it can all be controlled via a phone or tablet.
