<details>
<summary> 2020 - now </summary>
<br>
Currently working as a **DevOps** at [Kepler](https://kepler.space) 🛰️.
This is mostly a software (infrastructure) dev gig for a start-up, which is a bit new for me
coming from a more classical "DevOps" role for a mature company. 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:
<ul>
<li>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.</li>
<li>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.</li>
<li>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 <a href="https://en.wikipedia.org/wiki/Hardware-in-the-loop_simulation">HITL</a>
(Hardware-in-the-loop) testing to allow us to more reliably, and frequently test our HW.</li>
<li>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.</li>
</ul>
<p>Beyond my work as an Individual Contributor, I’ve also been responsible for instilling “DevOps”
principles within the team on our road to maturity.</p>
</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. Here is a subset of what we use
across multiple data-centers, with high-availability:
<ul>
<li>Infrastructure: VMWare, Physical</li>
<li>Provisioning: Ansible, Terraform, Cobbler</li>
<li>Containerization: Docker, Kubernetes</li>
<li>CI/CD: Git, BitBucket, Bamboo (we host the entire Atlassian suite in-house)</li>
<li>Monitoring:
<ul>
<li>TICK (Telegraf, Influxdb, Chronograf, Kapacitor)</li>
<li>ELK (Elasticsearch, Logstash, Kibana), with filebeat and metricbeat beats</li>
<li>Prometheus</li>
<li>Grafana</li>
<li>Nagios, Pagerduty, Pingdom</li>
</ul>
</li>
<li>Data: MySql, Aerospike, Kafka, HDFS, Druid</li>
<li>Scripting: Golang, Bash, Python. <em>Some</em> of my work can be on my Gitlab profile:
<ul>
<li>Golang:
<ul>
<li>a fast, containerized <a href="https://gitlab.com/kdam0/go-druid-mysql-influx">cron script</a>
that interacts with Druid, MySql, and Influxdb written in Go.
Basic unit testing.
This is a job that powers one of our major alerting dashboards.</li>
<li>a containerized highly modular <a href="https://gitlab.com/kdam0/devops-api">Rest Api</a>
that writes to Influxdb.
This is something we run in K8S as a Service to monitor Cronjobs that run in K8S.</li>
</ul>
</li>
<li>Python: a <a href="https://gitlab.com/kdam0/slack-to-teams">script</a> to migrate
Slack exports to MS Teams messages.
This is something we used when we gave up on Slack.</li>
<li>Bash: a small <a href="https://gitlab.com/kdam0/random-shell-helpers">collection</a> of helper
scripts that I used frequently for random things.</li>
</ul>
</li>
</ul>
</details>
<details>
<summary> 2016 - 2017 </summary>
<br>
I worked at [Achiga](https://achiga.io) (formerly *WebCanada*) as
part of my [PEY](https://web.cs.toronto.edu/undergraduate/pey) (internship)
program from UofT for 12 months. As part of this, I was involved in:
<ul>
<li>A fast paced Agile environment where I was a Full Stack Developer working with
<strong>PHP (Zend), MySql, and JavaScript</strong>.</li>
<li>Git + BitBucket + JIRA (basically the whole Atlassian suite), with Vagrant</li>
<li>The Pipeline team working on day to day features and bugs in the CMS powering thousands of
local hotel sites around the world for Starwood Hotels.</li>
<li>Debugging and optimizing cronjobs responsible for storing hotel rates in
our database which is critical to hotel revenue.</li>
<li>Contributing to the Gallery Page (CMS as well as user facing UI).
See <a href="https://designhotels.com/gallery">Design Hotels Gallery Page</a>
towards the end of my tenure.</li>
</ul>
</details>
<details>
<summary> 2014 - 2016 </summary>
<br>
I've worked on several other small-buisness type projects involving web, and scripting over the
years in between semesters.
