Shorter mandates, internal tools and platform work. Happy to detail on request.
Platform Cloud
Multi-tenant Kubernetes platform with high availability across three zones — RKE2, Terragrunt stacks, Vault-based secrets, ArgoCD GitOps and a zero-trust mesh across multiple cluster sets.
Observability stack
Central monitoring, log and tracing platform for cloud and on-prem workloads — Prometheus, Loki, Tempo, Grafana, Alertmanager. Audit-capable, multi-tenant, with clear SLOs.
Smart-home setups
Home Assistant installations for demanding private homes — ZigBee, KNX integration, energy monitoring, local voice control. No cloud dependency, all data stays in the house.
Deshisha
Delivery and reservation platform for shisha bars in the Lieferando style — aggregator, bar dashboard, order and reservation workflow, payout logic. Greenfield design, concept and prototype phase.
Back-office tools
A range of internal tools for mid-market clients — time tracking, lightweight CRM, reporting, order management. Built small, cleanly integrated, replacing Excel islands.
Architecture & security audits
Structured audits of existing cloud and application setups — security, scaling, run cost, time-to-market. With a concrete action backlog instead of slides.
