“What an incredible value and learning experience!” by Sean A.
In early 2014 I decided to start learning a programming language that can make my daily work easier and also boost my networking career. This is when I discovered that Python, being a great language for beginners, can help me write some scripts that connect to network devices and perform various tasks I was doing manually, thus saving a lot of time. Also, working as a tester, I used Python to automate a lot of network tests, about 250, in a short period of time, again reducing my workload.
For all the above reasons and because there is a lot of Python material out there on the Internet that may seem discouraging for you as a beginner, I decided to build courses that take you from zero programming knowledge to advanced topics, all in a hands-on fashion.
In March 2015 I started working on my first Udemy course, “Python Network Programming: Build 7 Apps”, without really knowing what is Udemy all about and with no prior teaching experience, either online or offline. I just wanted to try it for some reason, despite a lot of mental obstacles, a full time job and zero experience in teaching people.
I worked a lot on this first course, with countless hours of researching, recording and editing, but there was something that kept me going further. In May 2015 my course was approved by Udemy and was an instant success, despite my low expectations. Gradually, the course became a bestseller on other e-learning platforms, as well.
In April 2016, I finished working on Part 2 of the Python Network Programming series, called “Multivendor Environment”, after about three months of researching, testing, summarizing, simplifying, recording, editing and structuring the course content.
Finally, in September 2016, I released Part 3 of this amazing course series, called “Python Network Programming – Part 3: Scapy & Security Tools”, which in my opinion is very interesting and exciting for anyone wanting to enter the world of network security in a 100% hands-on fashion.
I am really putting a lot of energy and effort into each of my courses and I am always trying (and succeeding) to pay special attention to the smallest details and provide a lot of value to my students.
I really think my courses will get better and better, both by learning from my mistakes and carefully listening to the feedback I get from my students.
So, check out my courses and stay tuned for more!
