    I am an network engineer by trade and my skillset includes F5 loadbalancers, checkpoint firewalls, cisco switches, cisco and juniper routers. However I also have experience with python and currently am looking to freelance doing python projects. During the years I have written scripts for pretty much anything that can be automated. This includes but is not limited to: * Remote code execution and remote file management via paramiko * Text/log/configuration files modification based on specific needs via regex or specific rule sets * Excel/CSV data processing and modification * Web scraping via selenium, scrapy and beautifulsoup * SNMP automation * VPN and proxy rotation * API integration In addition to the areas where I already have experience with, I am also very comfortable learning quickly and implementing new techniques as needed. I am also very detail oriented which hopefully is reflected in my proposals where I analyze every project before applying. My proposals include outline of potential technical challenges with the project and clarifications/questions I might have gotten from reading the project details in order to get the project started as soon as possible.
