Hi.
I am very familiar with Python/Django with Postgres database. I have been working for a large financial ASP company. As a application engineer, I have developed multiple Python/Django web-application to support 24x7 production environment as well as integration of applications. Further more, I am experienced in supporting incident management and being on-call for production troubleshoot.
Although, I have not had any experiences with selenium, my experiences as a QA automation engineer can be translated well and shouldn't have much time to be proficient with selenium. I have mainly used SilkTest for automated tests.
My familiar Grunt, Javescript, and Heroku are minimum but I am confident I can be a skillful coder with some experiences.
I am very experienced in SDLC and will be valuable asset to your project.
