I specialize in writing Network Automation Infrastructure code, Network applications and System software for Linux and "Unix-like" OS's. The tools of my trade are Ansible, Python, C and C++. My Perl and shell-scripting skills aren't too bad either. I worked for more than 18 years at Cisco Systems, where I wrote software applications for IOS and IOS-XE switches and routers. In the process, I developed a deep understanding of how packets move, and about the boxes that make packets move. Outside of Networking, my areas of expertise include Linux and Embedded systems. I have hands-on experience with OpenStack and Docker. I have an understanding of Cloud Networking in the context of OpenStack Neutron. I possess decent writing skills, and a couple of my technical articles on the web register a few dozen hits every day. I take pains to document my work and explain them to my clients. I have received feedback telling me that I should have been a teacher. I have the ability to explain whatever I know in a clear manner free of jargon. I have 25+ years' overall experience in the software industry as a hands-on programmer. I've never been a people manager: all I've done for 25+ years is write, test, debug, deploy and support code. People familiar with my working style would describe me as "careful, methodical, systematic and logical" rather than "brilliant", "flamboyant" or "genius". Portfolio: ********** I divide my time between building solutions for my clients, creating open-source projects and writing the occasional article on programming network applications. My client projects include: - a set of Ansible playbooks (about 300 tasks in all) to install and configure an OpenStack instance on a single computer. The playbooks were embedded inside a Docker container, and running the container would start the ansible-playbook runs. The use-case was an IoT Edge installation, where the OpenStack instance would house VMs to run analytics on data coming from sensors. - an Ansible playbook to deploy and configure VyOS routers in an VmWare ESXi environment. Involved creating the router instances, creating VRFs and other related configuration. - a "domain name catcher" for Nominet in C: the work involved studying packet capture (PCAP) files using Python, running analysis using NumPy and matplotlib on the packet data, and using the insights thus obtained to tweak the behaviour of the C program. - use of profiling techniques to dramatically improve the performance of a C++ desktop network application: my client had a program that would scale poorly as the number of network hosts increased, which I was able to fix after studying the profiling results and reworking the data structures used in the program - a Perl interface to access Google Analytics - post-parsers in Python to process Google Vision API JSON outputs I am the author of several open-source projects, including: - an Ansible role that configures AAA, Layer-2, Layer-3, QoS and Netflow on a Cisco Catalyst switch. This makes extensive use of Jinja2 templates to generate the IOS configuration based on variables stored in YAML - a lookup plugin for Ansible that expands strings of the form "Gi3/1-4,Gi4/1-4" and generates a list of full individual interface names. This is extremely handy when writing Network Automation playbooks, for applying a configuration on a set of interfaces. - a Python PCAP to CSV converter (extracts fields from a PCAP file and populates the rows of a CSV document) - a Network Automation demo repository, where I have code to perform a particular network configuration task (creating a VLAN, its associated Layer 3 interfaces, IPv4 subnets and OSPF networks) using multiple approaches: Python (using the netmiko module), NETCONF/YANG, Chef, Puppet and Ansible I have a couple of fairly popular technical articles online: an article on Network Automation using various approaches, and one on using Python programming techniques to analyze packet capture (PCAP) files. Some examples of what I can do for you: ********************************************** - write/test/debug/deploy network automation code (Ansible playbooks, Python scripts etc.) - write/test/debug/deploy network applications, tools and utility scripts (in C, C++ and Python - Perl and bash/Bourne shell as well) - use standard GNU tools like gcc, gdb, gprof, gcov and make to build system software in C and C++ - create technical articles, blog posts, training material etc. on Networking and Network Automation - port open-source C/C++ projects to your platform
