Hi there,
I would be very happy to work on your project. I did few utility extensions for myself (for adjusting, fixing websites I use, like hiding posts from some users and showing best comments) they are published as Delfix and Banas but dont' look at them as a good example just that you know that I have experience :) I spend like 1hour for each only just to get things done which I needed. Didn't bother to work on design because that was not my goal.
In general, I have ~10 years of professional experience in software development. Let me know if you want to see my cv or have a Skype chat.
Regards,
Jonas Dimsa
