There is a ton of specialized *space* +related equipment here that presents interesting problems. +<br><br> +Beyond that, I've learned a ton about +embedded computers, networking and network automation, which has opened my world up to +cool home projects for which I am very grateful for. So far, I've been responsible for the +following: + +* Implementing a net-boot infrastructure using Packer, PXE, Awx (Ansible Tower) to keep our +RPi fleet images and configurations in-sync and up-to-date. +* Built a custom Linux router to support our lab's unique hardware testing requirements +for on-demand subnet generation/teardown, and develop Ansible roles switches. +* Completely revised our test-automation infrastructure by building a hardware-management +portal using Django with a RESTful Api (DRF) to facilitate reservation, +as well as [HITL](https://en.wikipedia.org/wiki/Hardware-in-the-loop_simulation) +(Hardware-in-the-loop) testing to allow us to more reliably, and frequently test our HW. +* Designed and deployed our on-prem Kubernetes cluster to be our software +platform going forward, while facilitating the migration to Kubernetes for all pre-existing +workloads, including (but not limited to) our various distributed databases. + +Beyond my work as an Individual Contributor, I've also been responsible for instilling "DevOps" +principles within the team on our road to maturity. +</details> + +<details> +<summary> 2019 - 2020 </summary> +<br> +Worked as a **DevOps Engineer** at [AcuityAds](https://acuityads.com) in Toronto. +The main selling point for me to work here is that Acuity does not use +AWS, GCP or Azure etc. to host its infrastructure, it has its own on-prem 'cloud'. +This presents substantial challenges for us as DevOps Engineers that would normally be handled by a +the public cloud provider. +<br><br> +Apart from this, due to the nature of adtech, we deal with a massive amount of data, which forces +us to be very specific about the types of technologies we use.
