About
I'm a Platform Engineer based in Trbovlje, Slovenia, building the internal developer platform at Sportradar used by engineering teams across the company. I design and ship tools that reduce friction, standardize workflows, and hold up under real usage — a custom Terraform provider, a CLI tooling ecosystem, and GitLab CI/CD standardization covering the full software lifecycle.
Experience
- Platform Engineer — Sportradar, Ljubljana (September 2023 – Present)
Internal platform team building tooling and infrastructure for company-wide engineering use. Shipped and maintain ~10 internal tools; implemented 106 production changes across 7 platform projects.
- Designed and built a custom Terraform provider for the internal platform API — data sources, filters, retry logic, naming-convention enforcement — with automated release pipeline and documentation, adopted by infrastructure teams
- Developed a CLI tooling ecosystem in Go: a server-access CLI (AWS SSM, Boundary, tmux workflows, signed and notarized macOS builds), an AWS profile/role management tool with SSO support, and a release-orchestration CLI integrating Terraform Enterprise and Aptly, distributed via Homebrew
- Migrated platform repositories to reusable GitLab CI/CD components and rolled out automated dependency updates (Renovate), standardizing test, build, lint, release, and publish pipelines across teams
- Extended the internal GraphQL platform API: JWT-based authentication rewrite, Azure SSO migration replacing LDAP, pagination, and VMware support for external partner infrastructure
- Built the internal developer documentation portal and an accompanying documentation generator, collaborating with the design team on UX — migrated from GitLab Pages to dedicated hosting
- Hardened platform security and access: Vault integration with custom role provisioning, Boundary connection methods, and LDAP-to-Entra ID migration across internal services
- Tennis & Crossminton Coach — Keber Sport, Radeče (July 2019 – August 2023)
- Designed and led training programs for students from kindergarten to college level; coached 15 students to regional competitions
