DevOps / Platform Engineer at Orion Innovation, maintaining Java services and introducing Terraform provisioning.

Lithuania

Message

At Orion Innovation, I maintain CI/CD pipelines and introduced Terraform-based infrastructure as code for backend systems on an EPCIS supply chain track-and-trace platform. I also investigate production issues across Java services, Kafka, gRPC, and Cassandra.

At Coherent Solutions, I proposed and led the migration of core services from Jenkins to GitHub Actions, containerised services with Docker, and deployed the platform on AWS. I also built backend services with Java, Spring Boot, and Hibernate.

I built my AI document-processing SaaS as its founder and sole developer, including its delivery pipeline and a Python application packaged with Docker Compose. I also manage my Proxmox home lab as code with Terraform.
