Looker Transactional Data Monitor

Set specified thresholds with incremental and decremental min and max values for important data points related to key transactions on an eCommerce company. This headless script uses the Looker API to pull the data and alerts stakeholders through Slack or email when thresholds are reached for a given data point. The script is tied into an interval timer (cron-like) on a Jenkins job and runs daily.

Mocha Headless Script for Twilio SMS Validation Through the API

This is a Mocha script that uses the Twilio API with two registered messaging numbers, one programmed with my current company's color-matching bot (Madi) to validate the text conversation flow with the bot.

Code Deployment Pipeline Script for GitHub Pull Requests

Written in bash for an Amazon Web Services EC2 Linux Server that uses cURL to make requests to the GitHub 3.0 REST API in order to merges pull requests into a release branch based on labels, checks for conflicts, alert stakeholders and ensures clean branches when conflicts or reverts occur. The bread and butter of any deployment pipeline on a continuous integration environment.

Anchor and Image Asset Validation Crawler

Specify the number of pages to crawl with a starting point. Scrapes all anchor tags and image tags for links, checks for valid response codes and crawls to a random anchor tag link that starts with your base URL. It supports both AngularJS and non-Angular pages. Never visits the same page twice and never validates the same link twice. Crawls until the limit is reached or when there are no more pages to crawl. A fun way to check the integrity of your links on your site on any given day.

Selenium Grid Testing Infrastructure

An in-house testing infrastructure with AngularJS support through Protractor for Chrome, Firefox, Safari. iOS and Android support through Appium. Supports Windows and MacOS systems. Fully managed by the Jenkins Continuous Integration environment for stability and reliability, with custom daemons written for MacOS for process management.

Sent Email Validation

This headless validation Mocha script uses the Google Gmail API to pull email data based on a time and subject line search query. It validates images, links, and text to be valid and structured a certain way within the email body. Very useful for marketing heavy companies through email channels.

UI Element Placement and Obfuscation Validation for iOS

Dynamic script written for iOS for testing responsive web applications to check for button placement, true obfuscation (if in the element is not within the default resolution view for a given mobile browser), and element view leakage (if the element is bigger than the current resolution supports, such as a purchase button being cut in half by the screen).

Looker "Looks" Report Monitor

This headless script validates the data structure and data types returned by "Looks" on Looker using their REST API. It does in-depth analysis of nested objects and data types to make sure that when saved queries on the system are updated by anyone, that they keep their integrity. This script is tied to the GitHub Pull Request API end-point and alerts Jenkins of any new pull request, auto-triggers the script, and reports to stakeholders on Slack.

Jenkins Job Health Monitor

This is a bash script that is tied into a Jenkins job that polls the job status of key jobs that keep a deployment pipeline running smoothly. It reads build XML for workspaces and, once a failure is found, it will alert stakeholders every minute until the job is repaired. Useful for when failures occur at night.
