01 — AUTOMATE
Make the repeatable repeatable
Reusable Terraform modules and Ansible roles reduce manual setup and make environments easier to reproduce and maintain.

01 / A bit about me
I like infrastructure that is boring in the best way.
Predictable, documented, automated, and observable. I work across the layers that help teams ship changes with confidence — infrastructure as code, configuration management, orchestration, and delivery pipelines.
02 — DELIVER
Build a path from code to platform
I connect Git-based workflows, CI/CD, Helm, and GitOps so platform changes can be reviewed, deployed, and rolled forward consistently.
03 — OPERATE
Think beyond deployment day
Networking, TLS, storage, access, and observability matter just as much as getting an application running.
04 — EXPLORE
Bring AI workloads onto platforms
Recent work includes deploying Open WebUI and SUSE AI components on Kubernetes and wiring up model/API connectivity through GitOps workflows.
02 / My toolkit
Tools are useful. Systems thinking is the real toolkit.
The technologies I use to provision, configure, deploy, and operate platforms.

03 / Career
Professional experience
DevOps Engineer
- Provision virtual machines on Harvester HCI using reusable Terraform modules and automate configuration with Ansible roles, variables, and Ansible Vault.
- Operate Kubernetes infrastructure based on RKE2 and Rancher; deploy workloads with Helm charts and Rancher Fleet GitOps workflows.
- Maintain self-hosted GitLab Enterprise Edition and Harbor, and build GitLab CI/CD pipelines for Terraform and Ansible workflows.
- Deploy Open WebUI and SUSE AI components on Kubernetes, deploy AI models, and configure API connectivity between model services and the interface.
- Manage persistent and shared storage using Longhorn and NFS, alongside connected storage systems.
- Configure networking and access with NGINX, ingress/reverse proxy, OPNsense firewall and DNS rules, and internal TLS certificates.
- Monitor infrastructure with Zabbix and troubleshoot platform and production issues across Linux and Kubernetes environments.
- Currently implementing Prometheus, Grafana, Loki, and Alertmanager for Kubernetes metrics, dashboards, centralized logs, and alerting.
DevOps Engineer
- Provisioned AWS infrastructure with Terraform, including VPCs, IAM, security groups, reusable modules, and state management.
- Automated configuration and operational tasks with Ansible.
- Worked with Amazon EKS, Docker, Helm, and ArgoCD to support containerized application delivery and GitOps workflows.
- Created and maintained GitLab CI/CD pipelines for infrastructure and application deployment workflows.
- Managed EC2, Auto Scaling, Elastic Load Balancing, Route 53, and health checks for availability and traffic routing.
- Implemented monitoring and alerting with Prometheus, Grafana, CloudWatch, and SNS; supported RDS read replicas and log forwarding to CloudWatch and S3.
- Configured NGINX and SSL/TLS for secure application delivery.
Software Developer
- Conducted comparative research for ReproduceMeGit, a tool analyzing reproducibility of Jupyter Notebooks in GitHub repositories.
- Benchmarked the tool against research requirements, visualized results, and developed a React interface.
- Created technical documentation to support knowledge sharing.
Data Analysis Intern
- Analyzed embedded-project data using Python, NumPy, and pandas.
- Collaborated with engineering teams on embedded-system data analysis and performance optimization.
- Created data visualizations and reports to support interpretation and decision-making.
04 / Selected work
A few systems I've helped bring to life.
A snapshot of the platform work behind the tools and services.
01 / Private cloud platformInfrastructure
Repeatable VM provisioning
Terraform modules and Ansible configuration turn VM provisioning and software setup on Harvester HCI into a repeatable workflow, with GitLab CI/CD supporting change delivery.
02 / Platform deliveryGitOps
Kubernetes through Git
Rancher, RKE2, Helm, and Fleet support consistent cluster application deployments and GitOps-based change management.
03 / AI platformEnablement
AI workloads on Kubernetes
Deploying Open WebUI and SUSE AI components, deploying models, and configuring API connectivity as part of a Kubernetes platform.
05 / HOW I THINK
From a commit to a running service.
I think about the whole path: infrastructure, configuration, delivery, runtime dependencies, and feedback from monitoring.

Say hello
Have a platform problem?Let's talk.
I enjoy talking about infrastructure automation, Kubernetes platforms, delivery workflows, and the practical details that make systems reliable.
