Hello,
Hope you're doing well.
I am a professional Python developer with 5 years and can complete your project on time and within your budget.
I have worked on similar projects to what you are looking for, and I am confident I can exceed your expectations.
I can start working immediately if you give me a go. I can get familiar with the code written by other developers so that I can grab the current project and start to add/modify features on them.
Thanks.
~Elena~
