Projekthistorie
Developer-tooling engagement at a major Canadian bank (regulated environment).
- Built shared CI workflows for quality and security gates (SAST, test, build) consumed by 250+ repos across the bank.
- Go webhook exporter putting GitHub Actions build duration, failure rate and gate coverage in Prometheus.
- Cut Docker build times from ~12 min to under 3 with BuildKit layer caching backed by ECR.
- Owned modernization of the bank's release automation: consolidated 15+ GitHub Actions (mixed TypeScript, Python, shell) into a monorepo.
Global industrial manufacturing company (€4.5B revenue, 20K+ employees) modernizing its digital product portfolio.
- Onboarded 5+ teams to Kubernetes, translating requirements into Helm and ArgoCD.
- Drove org-wide Karpenter migration (ADR-first, phased rollout), cutting EKS costs 20–25% with zero downtime.
- Led developer experience and CI/CD automation for 5+ product teams, enabling self-service deployments.
- Partnered with Finance to build an ROI model linking platform adoption to business outcomes, securing continued investment.
Centralized developer tooling & frontend infrastructure.
- Designed GitHub Actions release pipelines for 150+ packages: semver enforcement, quality gates, and 10k+ Playwright tests sharded across parallel runners.
- Owned the shared-code strategy across the monorepo and internal registries: versioning and release boundaries for 14 organisations and 200+ applications.
- Drove DevEx and platform adoption: established contribution standards and cross-team enablement processes for enterprise product teams.
