Curriculum Vitae

Systems-oriented engineering leader with 20 years of experience architecting, scaling, and stabilizing complex infrastructure and platforms.

Specialized in socio-technical systems, failure analysis, and risk-aware architecture. I combine hands-on system design with high-level technical leadership, focusing on financial efficiency, operational resilience, and cross-functional decision-making.

Selected Experience

HelloFresh SE

Staff Engineer / Engineering Manager | Aug 2021 – Present

  • Resilient Infrastructure: Led the architectural transition of the global Kubernetes platform from a monolithic structure to a multi-cluster topology, drastically reducing blast radius and systemic risk.
  • Developer Experience (DevEx): Designed and delivered a GitOps-based platform that abstracted multi-cluster complexity, accelerating onboarding and lowering the cognitive load for hundreds of developers.
  • FinOps & Efficiency: Architected and executed a data-driven database cost optimization strategy, yielding a €1.2M reduction in annualized cloud spend without sacrificing performance or reliability.
  • Pragmatic GenAI Leverage: Applied LLMs and GenAI capabilities as high-velocity diagnostic assistants to audit complex infrastructure footprints (such as RDS database fleets)—significantly accelerating pathfinder investigations and cost-leak identification while maintaining strict oversight of security constraints and model limitations.
  • Technical Governance: Standardized the end-to-end release lifecycle and established strict ownership boundaries, integrating automated security validation directly into the engineering workflow.
  • Leadership & Mentorship: Managed and mentored distributed platform teams, fostering a culture of technical excellence and radical candor that resulted in multiple internal promotions.

Sellers Marketplace Analytics GmbH

Lead DevOps Engineer | Nov 2020 – July 2021

  • CI/CD Standardization: Unified release practices across disparate engineering silos, resolving a long-standing delivery bottleneck.
  • Platform Blueprint: Designed a highly resilient AWS-based deployment framework for containerized workloads, ensuring consistency and velocity across the product portfolio.
  • Cloud Economics: Partnered with Operations to eliminate architectural waste, securing an immediate ~40% reduction in AWS infrastructure costs.

Jobtome GmbH

DevOps Engineer | Nov 2019 – Oct 2020

  • Kubernetes Migration: Architected a fully automated, multi-region Kubernetes platform for the core product, eliminating manual deployment overhead.
  • Delivery Velocity: Compressed pipeline deployment times from several hours to under 10 minutes, significantly improving feedback loops and system stability.

Sitecore GmbH

Senior Software Engineer / DevOps Specialist | May 2010 – Nov 2019

  • Cloud Leadership: Acted as the principal technical authority for cloud migrations and platform architecture, driving systems from conceptual design through production.
  • Platform Bootstrapping: Spearheaded the adoption of internal developer platforms, accelerating deployment times across multiple engineering business units.
  • Risk & Cost Auditing: Conducted comprehensive cloud health checks, advising executive stakeholders on risk mitigation, security posture, and financial guardrails.

Core Competencies

Infrastructure Strategy

Systems thinking applied to cloud platforms, high availability, and large-scale migrations.

Risk Management

Post-mortem facilitation, root cause (contributing factors) analysis, and designing for failure.

Business & Tech Alignment

Translating technical complexity into financial realities (FinOps) and strategic trade-offs.

Socio-Technical Leadership

Bridging the gap between software architecture and team organizational structures (Conway's Law).

The Certification Stance

"I believe in demonstrated capability, not badge collecting."

Over my career, I have held more than 25 active industry certifications, including:

  • AWS: Solutions Architect Professional, DevOps Engineer Professional, Security Specialty, Database Specialty, Advanced Networking Specialty.
  • Google Cloud: Professional Cloud Architect.
  • Kubernetes: CKA (Certified Kubernetes Administrator), CKAD.
  • Agile: Professional Scrum Master I & II, Professional Scrum Developer.

Note on Expiration: I have intentionally allowed all of my certifications to expire. The engineering principles and deep domain knowledge stayed with me; the recurring renewal fees to multi-billion-dollar cloud vendors did not.
