About Us

Our Courses

Since 2014, we have offered paid courses on network automation including courses on Python, Ansible, Netmiko, and Nornir.

Open-Source Work

Since 2014, we have been contributors to various Network Automation open-source projects.

In 2014, Kirk began work on the Netmiko library which simplifies automating legacy screen-scraping. We have actively maintainted that library since that time and have increased the Netmiko driver support to over eighty vendors.

In addition, to our Netmiko work we have done extensive work on the NAPALM automation library. Kirk is one of the core NAPALM maintainers. He was a key contributor on the Cisco IOS driver for NAPALM. He also has maintained many aspects of the NAPALM NX-OS driver and the NAPALM-Ansible modules.

Twin Bridges has also worked on the Nornir Automation Framework including maintaining the nornir-netmiko bindings and helping with several other Nornir plugins.

Student Success

  • I decided to take Kirk's courses on Ansible and Nornir during the stay-at-home-orders in 2020 when COVID-19 hit the world. After the first few lessons I was able to write my first script to check for and add VLANs to our NX-OS environment.

  • I have taken several paid and non-paid Python courses. I can say that by far your course is the best one I have taken. The way you explained stuff just makes sense to me.

  • I am on the material for the 3rd week and I just wanted to compliment you on the way that you explained how to unwrap the data structures. Best step by step explanation I have seen so far to help me understand and work with the data. Thank you very much!
