Thank you for looking at our bid. Request your comments on the following (1)I believe the requests to database is going to bypass the Django site, can we propose a Tornado based http server as proxy - maybe another connection pooling here for the Postgresql? (2)Regarding your existing Django - I believe this is for other requests and it continue to use SQLAlchemy & the new Postgresql database. Looking forward to discuss. Kindly check out my Freelancer portfolio https://freelancer.com/u/fleetways.html for previous work. Looking forward to an opportunity to discuss this project further.
