Automating internal GCP infra management with GitOps and terraform (On going): - Create GCP infrastructure (projects, kubernetes clusters, virtual machines etc.) with github actions triggered via github pull requests. Terraform/terragrunt orchestrates the resource creation into GCP upon merge.
DevOps Lead
Tuxera Oy
2016-11 - 2021-01
Implementing DevOps practices to Tuxera product lines: - Continuous performance testing: Implemented ELK stack for automatic ploíing and alerting of performance/functional testing. Fasten Continuous Integration (CI) system: Implemented ways to build/smoke test Tuxera filesystem CI to report(email) /notify(chat) within 30 minutes of every commit.
Implementations with Kubernetes: - Examining kubernetes container storage interface for Tuxera file share in Azure kubernetes service. Implementation also involved knowledge of storage accounts, compute etc.
- Integrating AD (active directory) authentication with a Tuxera file share container running inside kubernetes.
- Testing with Kubernetes: Implement testing application failover with kubernetes.
Implemented Kubernetes Container storage interface for MooseFS (a fault tolerant distributed file system) with golang.
DevOps team lead: - Have experience leading a small team, performing sprint planning, scrum checks and holding retrospectives.

Introduce and implement hybrid cloud computing systems: - Ability to scale to AWS infrastructure on peak loads with AWS- Autoscaling, e.g. selenium grid infrastructure with selenium- nodes elastically scaling on AWS during peak loads.
Participated in helenius streaming project backed by AWS-CloudFront for streaming helenius fight for local customers oæloading peak load to AWS from production site From monolithic systems to Microservices: - Constructed weblogic systems into vagrant boxes with files mounting from host for developers to start developing locally oæline. After understanding the drawbacks, those we containerized to multiple docker containers orchestrated by docker-swarm.
Implemented tiered container infrastructure with automated Build (QuickBuild), store (Artifactory docker registry) and deploy (QuickBuild).
Implementing and improving Continuous Integrated release systems for downtime free releases: - Implementing tools for providing infrastructure for continuous development and release to the production site, in a direction to achieve a complete down time free release cycles.
Studied and introduced git to the developers and deployment plan for smooth transition.
Also, responsible for maintaining daily automated lab installations, maintenance of automated selenium grid servers and implementing improvement ideas for faster execution times.
