Profile
Engineering leader with 15+ years in platform engineering, cloud infrastructure, and distributed systems. I build and scale cross-functional teams that own critical platform features end-to-end.
I specialize in cloud-native platforms on Kubernetes, developer tooling, and reliable systems. In recent roles I’ve grown an EU engineering hub, led cross-team initiatives, and combined hands-on Go/Kubernetes work with coaching 16+ engineers. I own both technical direction and execution.

- Introduced automated testing, coding standards, and CI/CD improvements.
- Implemented containerization, observability (Prometheus, Grafana), and structured logging.
Senior Backend Software Engineer
- Backend engineer for Galera Manager – a management and monitoring tool for Galera Clusters.
- Designed and implemented Go services integrating monitoring, management, and CI/CD on Kubernetes.
Head of Development / Senior Engineer
- Led a team of up to 9 engineers; transitioned a legacy monolith to microservices on Kubernetes.
- Implemented CI/CD, code quality standards, security practices, and observability tooling.
Advisory Work
Technical Advisor / Consultant

- Led a small distributed engineering team, defined long-term architecture, and guided the platform through multiple iterations.
- Owned development and production environments, CI/CD, and code quality processes; act as ongoing technical advisor.
Personal Projects & Open Source
- Developed network analysis and monitoring tools: TCP/IP protocol analysis, packet inspection, and traffic pattern recognition for defensive security purposes.
- Author of prometheus-metrics-bundle (Symfony) with 3.5M+ installations and 170+ GitHub stars — widely adopted observability library.
- Created and maintain error handling libraries and linters (Go) used in production by multiple teams (errx, nolintguard, collaborator in revive).
- Contribute to CNCF projects (Kanister) and open source (go-extras, kopia, others).
- Recognized as an Arctic Code Vault Contributor with achievements such as Pull Shark and Starstruck.
