Code Portfolio

demo-jenkins-config-as-code

A showcase of Jenkins configurations and job creation out of the box. Using groovy and the configuration as code plugin, you can create fully viable Jenkins instances on docker.

python_resume

A showcase of Python/Flask/Jinja2/HTML(5)/Bootstrap/JQuery used to both generate jon-kelley.com and my hardcopy resume.

logdna_line_export_cli

This command will recursively fetch all logs from the logdna export API. This is useful to get logs beyond the 10,000 line limit as the API does not natively provide pagination.

rebrow_modernized

Built for the Python developer who needs to look into a Redis store. Allows for inspection and deletion of keys and follows PubSub messages. Also displays some runtime and configuration information.

carphunter

Simple tool to locate Cisco IP/ARP and display results. Useful for small to medium datacenters (1-100 network devices)

zabbix_api_monitor

This was created to monitor HTTP / REST Endpoints under Zabbix.

canakit1104-api

This was created to expose a REST API for a relay board microcontroller so we could build light-based alerting systems while at Rackspace.

testVapi

Based on the python behave features this project emulates a cucumber style syntax to run HTTP API tests and is able to forward the messages to ELK stack. This uses a language called Gherkin to make plain-english QA testing a breeze.

vagrantfile-skel

I made this repo because I keep encountering quick environments setup / breakfix I need from time to time.
