Oct, 2016 - Jan, 2018

After transferring internally to AWS Monitoring, I joined the CloudWatch Console UI team who owned the the customer facing UI for AWS' metric and alarming service. Below are some key moments:

  • Adding the ability to hide autoscaling alarms (legacy gwt code) from the alarms summary. This was a highly requested feature by AWS customers
  • Adding the ability to specify any previous Console UI deployment front-end code to be executed against the checked-out version of the back-end code (API). This was for backwards compatibility testing after a bad deployment
  • Owning and delivering the UI development of Metric Math, CloudWatch's newest feature that allows metrics to me manipulated and normalised via expressions - https://amzn.to/2HcTBwz

Jun, 2014 - Sep, 2016

Upon first joining Amazon, I was a member of a team who developed several tools used daily by Network Engineers to maintain (update, change, fix, etc.) the ever-growing Amazon network. Here are some personal highlights:

  • Creating and owning a tool that allowed the updating of OS Firmware on JUNOS devices in a hands-off manner
  • Contributing to an org-wide push for automation (supervised automated execution) implementing safety measures and auditing of changes to be executed
  • Designing, peer-reviewing, and building a web portal to aggregate the many networking services into one over-arching view of the entire network
  • Driving adoption by talking to, and surveying, the most active users and quickly iterating changes based on feedback. Now widely used among Amazon Network Engineers

OneNote.me

Creator

Jan, 2020 - Feb, 2020

I made this as I struggled with sharing deep links to OneNote in Slack and other applications. OneNote links use a "onenote:" prefix that opens links in OneNote, however this does not work with chat apps. Using OneNote.me solves this issue.
