SUMMARY

I have years of experience running computers ranging from running 2,000 servers at Amazon to a single scientific application for the United States Forest Service. I have detailed knowledge of how networks work and how they fail. I have extensive experience with python. I have some experience running MySQL. My experience is illustrated in specific accomplishments below.

EDUCATION

Certificate Cyber Securioty Coding Dojo

Certificate Amazon Web Services (AWS)/ University of Washington June 2014

Certificate Python Programming/ University of Washington June 2011

B.S. Physics/ Harvey Mudd College

GOALS

I would like to use Python for some sort of operational, networking, or testing task. I've used python to analyze network behavior and test network devices. However, if a Natural Language Processing opportunity or a scientific programming opportunity came my way, I would certainly take it.

ACCOMPLISHMENTS

●●At Expeditors, I converted 81 servers from control of the IT organization to control of my group, including installation of Ansible, software updates, and security updates.
●●At Varsity Tutors, I had 3 5-star ratings and 1 4-star ratings, an average of 4.75 which is almost but not quite in the top 10%.
●●While at Microsoft, I automated test procedures for a new controller for Azure servers.
●●While at Downtown Emergency Services Center (DESC), I demonstrated how they can use their existing systems to generate business intelligence and manage their operations more effectively. I made some harnesses to reduce the time required for COVID-19 remediation. Showed how to use existing inspection procedures to improve safety at zero cost.
●●While at AT&T, worked on a better monitoring system for several dozen nameservers in a software development lab.
●●While at Tata Consultancy Services, I was dedicated to the T-mobile account. I did Root Cause Analysis (RCA) on a major outage, including creating a business argument for migrating into the cloud to eliminate constraints that had contributed to the problem. Reduce monitor false alarm rate by 90%
●●While at Amazon, wrote software in python to search for misconfigurations in network devices. Also automated patching processes for 2000 hosts, which went from 0 hosts/day to 89 hosts/day.
●●While at Juniper, wrote automatic test software to verify that there are no regressions as JunOS software gets updated. I used PyEZ which runs over NETCONF, RFC 6241, paramiko and netmiko.
●●While at Maxset LLC, wrote many research softwares to synthetically translate natural language texts in to the skyset format. See https://arxiv.org/pdf/1511.02117.pdf. I wrote a tutorial, some of the heuristics, a logging system using elasticsearch, logstash, and kibana (ELK).
●●While at Tommy Bahama, wrote a program in python that visited all known linux and solaris servers and recorded their input and output dependencies. Converted the monitoring system from Big Brother to nagios. Maintained software and configuration on A10 networks load balancers. Participated in on-call for production critical systems. Wrote documentation for systems, including playbooks for outages.
●●While at Disney, I wrote software in python to manipulate F5 LTMs through iControl. I used chef and ruby to automate turning patching servers. Gave presentations on wireshark, Elasticsearch, Logstash, and kibana (ELK), and openssl.
●●While at UIEvolution, I wrote two documents that described the systems being deployed, one for the clients and one for the servers at AWS.
●●While at Sweetlabs, I wrote a python program that translated virtual machines images into OpenStack volumes, configured networking in neutron, and created an instance on nova.
●●While at Google/Widevine, I gave a talk on algorithm analysis and Big O notation, with examples written in Python. I also gave a talk on applied cryptography. I worked with Juniper SRX 3600 firewalls, Juniper EX8200 switches, and Juniper MX-80 routers. I transitioned the team from Juniper SA2500 VPN to OpenVPN. I documented processes, procedures, and configurations. Ran backups using both CommVault and Amanda. I managed machines running Windows Server/2008R2, Linux and several BSDs
●●While at Google Compute Engine, I verified that the documentation for Compute Engine was both correct and clear, by writing many python programs. I wrote a python program that would spin up 500 instances of compute engine in less than 90 seconds. I assisted Google Compute Engine customers worldwide learning how to use the system at multiple levels.
●●While at F5 networks, I won 2nd place in the Contest for Service Improvements for suggesting that each error message be given a unique number. I then built a database keyed by these numbers with detailed explanations of the error and remedial action. I also got 5 nominations from coworkers for innovation, excellence, and commitment. Consistently achieved performance and customer satisfaction goals. Wrote a document explaining how key features of the support lab worked and how to use them. Wrote several solutions for publication to our customers, one of which was the most read in F5's DevCentral website in one quarter
