Hi, i have 9+ years of custom web-development experience, mostly on php/mysql using lot's of various APIs like google apis, twitter api, different photo stocks apis, payment gateways etc. Have no problem to work with somone else code. Usually i'm working on custom coded framework, so can't show lot of wordpress plugins developed. Can describe only one i think is suitable. It is tournament system based on elo-rating. So admin part have interfaces to enter players and matches and frontend part have shortcodes for displaying rating table and match log. What i want to say is that i think coding experience is more important in your project than wp development. I know wp internals/api and you already have plugin which is working so i think it's not a problem. Anyway i prefer to look at your code to be sure i can work with it.
As about requirements point by point:
- my english i think is rather fluent, practicing a lot while talking with customers and discussing details of projects, though grammar is not perfect as it is not my native language (i think you understand from this text)
- wordpress experience i described earlier
- OOP i'm using constantly as working with MVC frameworks and APIs etc
- javascript and jQuery are good, constantly using it in projects
- expert in SQL queries as i'm focusing on complicated database driven projects
Sorry, char limit of this message reached so contact me if you interested
Thanks,
Dmitry
