Work Experience
Senior Cloud Infrastructure Engineer
2022 - PRESENT
Questrade
- Did brownfield-heavy work. Migrated a 2500-line parser to a proper modularized model, doing type, value, and consistency validations.
- Handled performance bottlenecks in the reasonably complex CI/CD pipelines used by the company.
- Gained experience as a platform engineer. Gathered requirements from teams on resources they want to use from GCP to the platform definition that is run by our team.

Mendix
- Created a multi-region infrastructure layout for deploying platforms consistently and uniformly using Terraform and Kubernetes.
- Documented obscure aspects of the company infrastructure, making it easier to onboard new members and share knowledge.
- Improved the scrum ceremonies to produce more explicit and easier to split stories to allow the team to work more efficiently.

Software Engineer
2018 - 2020
Avenue Code
- Implemented the first Kubernetes clusters used in production for the client over an on-premise infrastructure from scratch.
- Implemented a deployment solution to replace unmaintained continuum deployments with simpler and more reliable GitLab CI pipelines using Ansible.
- Implemented a self-service Kubernetes cluster creation solution for on-premise infrastructure.

DevOps Supervisor
2016 - 2018
Stilingue
- Implemented on-demand test environment creation for developers to test their work over OpenShift based on entirely self-service branches.
- Pitched, proposed, and implemented the company's migration to OpenShift as a platform, making deployments simpler and more reliable.
- Created the first configuration implementation as code for configuring on-premise VMS in the company using Chef.
- Implemented the first deployment automation for the company using Chef over heterogeneous environments and configuration requirements.
- Implemented the first CI pipelines for the company using Jenkins.

Experience
Environment Creation on Demand Using OpenShift
One of the companies I worked for did social network monitoring, which made testing difficult for back-end developers since they could get blocked for overusing access keys. To overcome this, I created a solution that would automatically build the branches and provide a form in OpenShift. This form allowed the developers to select a version, number of replicas, and other parameters to test their apps.
Multiregional Cluster Setup with Terraform
A full setup for EKS clusters across maturities and regions. The setup included VPC/networking, IAM permissions, service accounts creation, and Amazon Route53 entries. The pipelines for deploying the infrastructure were created using GitLab CI, with selective job creation based on the changed resources to prevent long-lasting pipelines. Using SSM and AWS Secrets Manager, we could share the sensitive information between Terraform and Helm installations.
Replacing Deployments to a Lightweight Solution Using GitLab CI and Ansible
To replace unmaintained Windows deployments pipelines defined in Continuum, a proprietary CI/CD tool, I proposed a replacement using GitLab CI and Docker images with Ansible. The solution greatly fixed some long-standing issues with deployments, such as long-running pipelines, simpler retries, and simplified use.
