Senior Freelance DevOps & Platform Engineer
I help engineering teams build, automate and operate cloud-native platforms and Linux infrastructure, with a focus on Kubernetes, Infrastructure as Code, CI/CD, observability and release engineering.
I am a freelance DevOps and Platform Engineer with more than ten years of experience across software engineering, Linux infrastructure and cloud-native platforms.
I work closely with development teams at the intersection of software, infrastructure and operations. I build and evolve platforms, automate infrastructure and delivery processes, support migrations and solve technical problems that cross traditional boundaries.
For me, good engineering is also good collaboration. I value clear and respectful communication, raise challenges early and work toward practical solutions that make sense for the people who have to build, operate and use the systems.
How I help engineering teams
Designing and evolving Kubernetes-based platforms and the supporting infrastructure and tooling that give development teams a reliable and repeatable way to build, deploy and operate software.
Building and migrating cloud infrastructure with an emphasis on automation, reproducibility and controlled transitions, reducing manual steps and making infrastructure changes more predictable.
Designing delivery pipelines, release processes and packaging workflows that make software delivery repeatable, traceable and easier to operate across environments.
Building logging, metrics and observability solutions that help teams understand system behavior, identify problems and operate production environments with better visibility.
Automating Linux systems and platform components to reduce manual work and make provisioning, configuration, packaging and system changes more consistent and maintainable, while retaining the depth needed for system-level troubleshooting.
A selection of recent freelance projects across platform engineering, cloud infrastructure, Linux systems, release engineering and observability.
Designed observability infrastructure for cloud services and Linux-based POS systems using OpenTelemetry and Dynatrace. Improved CI/CD and staged release processes, automated Secure Boot integration for custom kernel modules, and built reusable Jenkins pipelines for RPM packaging.
Supported the setup and migration of a secure Azure-based platform, implemented GitOps workflows with Flux, GitLab and Jenkins, and automated Linux-based POS systems with Ansible and Bash. Built tooling for controlled RPM repository management and worked across platform, software, security and networking teams.
Engineered and automated Linux-based POS platforms with Ansible, Bash and Jenkins. Built reusable provisioning components, investigated issues across hardware, operating system and application boundaries, and designed staged operating-system and software release processes, including a proof of concept for passkey-based NFC authentication.
Supported the production migration of a Kubernetes platform from on-premises infrastructure to AWS. Coordinated migration activities and worked with the DevOps team during the production cutover with a focus on minimizing downtime.
Prepared Kubernetes-based development and sandbox environments for migration from on-premises infrastructure to AWS. Implemented infrastructure with Terraform and Ansible, analyzed the existing environment, prepared migration runbooks, and supported the migration of workloads and supporting infrastructure.
