Experienced PHP Developer (US candidates only!)

Description

SKILL SET:
Looking for an experienced PHP developer (5+ years exp) who speaks English fluently. Ability to do CSS is an added plus. I am looking for someone who can write clean code to modify the functionality and behavior of plugins (not just installing them or modifying the CSS). I want my site to run in such a way that the custom code makes the plugins interlinkable with each other.

These are the main plugins used on our site:

BuddyPress (aka BP)

WP Courseware (LMS)

Social Gallery and NextGen Gallery (the two are integrated)

(plugin developer site links at bottom of post)

CURRENT ISSUES: I have issues with the following that I need fixed:

BP login: accepts usernames that WP login sees as invalid

WP Courseware running as it should w/o complication.

Add Categories capability to WP Courseware.

Student portal accurately listing each student’s course(s) and lessons (part of WP Courseware)

Integration/setup of Social Gallery-Next Gen Gallery with WP Courseware

Setting up BP to restrict/organize student social network into groups that don’t cross over into each other. I.e., I want to protect one group from being infiltrated by another group. Contact for more explanation and a possible solution from the BP forum.

Setup of gradebook with WP Courseware add-on

Check our e-commerce setup (JigoShop) for errors, improvement.

APPLICANTS: Please provide following info to be considered:
1. Any questions/comments re items above?
2. Your location and experience.
3. Please provide sample plugin(s).
4. Your favorite color.

Thank you for your interest!
