At, I led a journey of the transition from an old legacy way of deployment, integration, and hosting processes to new, cutting-edge technologies and services.

We reached zero downtime during three consecutive years and reduced the risk of buggy code in production. We dramatically decreased the cost of infrastructure on another cloud and optimized the number and usage of services. And last but not least, I designed and implemented a multi-CDN approach of delivering traffic to end users. The service automatically switched the CDN for end users based on the current traffic quality in their location. We reduced the cost of traffic and increased the overall quality.

Authentication Service Based on Azure AD B2C

In Eve Virtual, we implemented authentication based on AD B2C. I created user flows and custom policies. Also, I created Azure Function to get certain data from the database during authentication flow. And we migrated user accounts from the legacy system to AD B2C. The team designed UI forms, and we hosted customized login forms. The team designed the email template used in user flows for OTP, reset password, and email verification.

All configuration files, technical profiles, and related assets were stored in Git (Azure DevOps) and CI/CD pipelines were configured to deploy updates automatically to staging and production environments.

SaaS for eCommerce

An eCommerce SaaS service for secure and seamless creation of eCommerce application instances (initially designed for WooCommerce but can be used for any web application).

Instances were hosted as deployments in a shared Kubernetes (AWS EKS) cluster. Each of them uses a separate database in a shared MySQL Cluster (AWS RDS) and a separate file system in a shared NFS (AWS EFS). All secrets were generated and stored in AWS KMS (separate instance per tenant)

All automation was done using terraform. I created a separate workspace per tenant, and all states were stored in S3.

CI and CD for application were implemented in GitLab CI—test and build images, push to the container registry (AWS ECR), and schedule rollout.

Terraform configuration was stored in Git repository in Gitlab, and CI/CD was configured to update core infrastructure and tenant's instances thru pipelines.

Android Application Build Automation

Implemented the CI/CD pipelines' automation to build, sign, and deploy Android applications for

Applications were uploaded to the Play Store manually after QA. Pipelines were implemented using GitLab CI and run on an on-premise dedicated server. At the time, we used a self-signed certificate.

Multitenant SaaS Application

As the only DevOps engineer in the project, I helped the client optimize and secure the current architecture in Azure Cloud using serverless services. Also, I implemented it as IaC modules with CI/CD pipelines and designed the backup and disaster recovery plan. Further, I estimated the cloud infrastructure cost and created a framework to assess the future cost based on the number of users.
