Hello lovely developers, I am in the final phases of a Python project that requires ADDING MS SQL SERVER support to the database interaction code. The current database backend being used is Postgres...department "doesn't support Postgres", so MS SQL Server is what we have to change it.) This work will require enough testing and understanding of the source data to confirm that the new MS SQL adapter code produces the same data that the Postgres code was producing. As such, please expect at least 20 hours of work spent writing or editing tests (in Python). Note: Please do not propose using SQLAlchemy *UNLESS* you can prove to me that the estimated lines of code that will change is *significantly* fewer than the lines of code that would be added simply by adding SQL...

We have a running web-based Python service running on an AWS EC2 machine. The data is stored in an AWS RDS MySQL database. We have a communication problem between the two. Sometimes, the requests made by our Python software are being dropped with this error "lost connection to mysql server during query". The code was done by a previous employee and we're pretty sure that the problem lies in a poorly made connection code. We're looking for someone to fix this bug and probably more if the work is done right.

We have a PHP backend implementation consisting of 15 files of 20 - 35 lines each. We have a strong preference for using Flask for the back-end instead of PHP. Therefore, we this implementation needs to be converted to Python/Flask. The existing implementation uses PDO as database driver for connecting to a MySQL database. We prefer to use SQLAlchemy. The current implementation has a working Angular11 frontend. The Flask implementation should be working correctly with this Angular frontend.
