My name is Kumar. Many people call me 'kd', I'm known for being...
- that guy who hosts his own website, email, dropbox, and vpn
- a real stickler about 'oPtiMiZing mY woRkfLoW' by scripting anything script-able
- a programming purist, and linguistic enthusiast
- down on social-media. I think they are designed to make people 😥
- a B.Sc in Computer Science at the University of Toronto with a focus in Natural Language Processing

Work Experience

[2020 - now]
Currently working as a DevOps Specialist at Kepler 🛰️. All of our infrastructure is in-house and I'm working with a variery of interesting low-level HW - raspberry pis, RF Matrix etc., which is a totally new context for me, coming from k8s, ES world. There is so much specialized "space" related equipment here that it presents a great oppurtunity to develop and refine my skills. Beyond that, I've also learned a ton about networking and networking automation. I am currenly the only "DevOps" guy here, but I've met a few people that know the important stuff just as well.

[2019 - 2020]
Worked as a DevOps Engineer at AcuityAds in Toronto. The main selling point for me to work here is that Acuity does not use Amazon or Google or MS (or whatever other 'cloud platform') to host its infrastructure, it has its own private Linux based 'cloud'. This presents a substantial set of challenges for us as DevOps Engineers that would normally be handled by a 3rd party provider.
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, often in multiple clusters:
- Infrastructure: VMWare, Physical
- Provisioning: Ansible, Terraform, Cobbler
- Containerization: Docker, Kubernetes
- CI/CD: Git, BitBucket, Bamboo (we host the entire Atlassian suite in-house)
- Monitoring:
- TICK (Telegraf, Influxdb, Chronograf, Kapacitor)
- ELK (Elasticsearch, Logstash, Kibana), with filebeat and metricbeat beats
- Prometheus
- Grafana
- Nagios, Pagerduty, Pingdom
- Data: MySql, Aerospike, Kafka, HDFS, Druid
- Scripting: Golang, Bash, Python. Some of my work can be on my Gitlab profile:
- Golang:
- a fast, containerized Cronjob that interacts with Druid, MySql, and Influxdb written in Go. Basic unit testing included. This is a job that powers one of our major alerting dashboards.
- a containerized highly modular Rest api that writes to Influxdb: . This is something we run in K8S as a Service to monitor Cronjobs that run in K8S.
- Python: a program to migrate Slack exports to MS Teams messages: . This is something we used when we gave up on Slack.
- Bash: a small collection of helper scripts that I used frequently for random things.
- Golang:

[2016 - 2017]
I worked at Achiga formerly known as WebCanada as part of my PEY program from Uni for 12 months. As part of this, I was involved in:
- A fast paced Agile environment where I was a Full Stack Developer working with PHP (Zend), MySql, and JavaScript.
- Git + BitBucket + JIRA (basically the whole Atlassian suite), with Vagrant
- 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.
- Debugging and optimizing CRON jobs responsible for storing hotel rates in our database which is critical to hotel revenue.
- Contributing to the Gallery Page (CMS as well as user facing UI). See Design Hotels Gallery Page, towards the end of my tenure.

[2014 - 2016]
I've worked on several other small-buisness type projects involving web, and scripting over the years in between semesters.
