Hi,
My name is Jose Garrido and I'm from Venezuela. I'm starting to bid on projects like this to get myself a good reputation within freelancer.com.
I have 6 years of experience building larga and medium sized PHP websites, systems and platforms in projects ranging from 1 month up to 6 months. Given my experience and habilities I can finish any project you want that uses those two skills you mentioned: PHP and PostgreSQL. Actually my last two projects were developed using Laravel so anything I build using that framework will be top noth, organized, efficient and fast.
Please choose me for this project and you won't be dissapointed!
Looking forward hearing from you.
Best,
Jose
