This is a demo of an open-source coding project.

I have created DevOps pipelines on Jenkins, ARM templates, connections, and the ELK stack set up for demo purposes for this real-world demo application, Conduit.

The pipeline includes building the docker images after code changes, pushing to a container registry, then creating a PostgreSQL database as a container on a different VM, then deploying the app to Azure Web Apps PaaS solution using ARM templates. Logging is handled using the ELK stack.

The database is backed up twice a day using the pg_dump utility on the Docker host VM. This backup can be pushed to any persistent storage in a real-life scenario.

This project also includes a recurrent pipeline for cleaning up orphan docker images in the VM when new builds are pushed to the container registry.

Marcel is a collaboration tool for the 90,000+ employees of Publicis Groupe that works as a web and mobile app for iOS and Android.

This app allows people to find news updates, collaborate with each other, find information about different communities, find new internal gigs, help and teach each other, learn through Marcel classes, and much more.

I contributed to DevOps at Marcel, making it a very mature and stable product. When I joined Marcel, it could take around two days for a new release deployment to occur, but now it only takes a few hours. We are releasing a new version every week which earlier we could not think of. A few examples of my significant contributions include:
• Helping in the Kubernetes flavored Marcel rollout, including framework development.
• Creating a generic Helm chart deployment framework suitable for any app like deployment, cron job, job, and pod.
• Automating the reduction of app replicas on weekends (non-peak hours), achieving monthly cost savings of $1,000-$1,200.
• Integrating six different types of test frameworks into a one-click deploy pipeline which queues up around 24 tests to be run in parallel with just a single click.

Meddo is a healthcare web and mobile app for iOS and Android that connects patients with doctors, helps them book appointments, provides medicines at the clinic and home, schedules lab tests, picks up samples from home, and more.

I contributed to DevOps, cloud, and system administration work at the Meddo Health app. A few examples of my significant contributions are:
• Helping in the Kubernetes flavored Meddo app rollout, migrating from an Azure PaaS solution, and relocating a few apps from AWS.
• Creating Helm charts for 30+ apps.
• Building CI/CD pipelines with Drone CI.
• Performing all system administration tasks such as onboarding new teammates and providing access to different teams (IAM/RBAC).
• Collaborating on all cloud-related work like provisioning VMs, creating DNS entries, managing traffic, and more.
