About

M.Sc. in Chemistry & Plasma Physics. 16 years of progressive IT: embedded IoT QA → full-stack web → CTO-level ownership of a 70+ node bare-metal cloud and its AI/ML serving stack. Last 5 years: designing CPU-constrained computer-vision and VLM inference chains for edge and cloud. Still the escalation point for the company's smart-home integrations.

Last 5 years dedicated to **AI / MLOps**: building and deploying computer-vision and VLM inference chains on CPU-constrained edge hardware and cloud, with full CI/CD, observability, and DevSecOps ownership across a **70+ node bare-metal fleet** (HashiCorp Nomad / Consul, Zabbix, self-hosted GitLab).

Strong at the intersection of **systems thinking from the sciences, hands-on Linux/cloud operations, and applied ML** – from a 40 MHz sensor node to a multi-tenant cloud platform.

  My latest projects focus on DevOps and MLOps pipelines and monitoring of cloud applications (online documentation, support ticket platforms, marketing system, SysAdmin dashboards, etc.) as well as backends (search engines, computer vision prediction APIs, provisioning tools, service meshes, etc.) - from the developers PC through source control and onto the internet - agile, observable and cloud-native.

Experience

Feb2023

INSTAR Deutschland GmbH (Waletech) Shenzhen, China
Chief Technology Officer
present

Architected a CPU-only AI inference chain: YOLO object detection → face & ANPR → fine-tuned SmolVLM scene observer. Quantised (LiteRT / OpenVINO) for edge and cloud. 10 000+ detection tasks / min in production. Built MLOps pipelines (data → training / fine-tuning → model registry → serving) with automated transfer-learning loops, version-controlled in GitLab CI/CD. Migrated a multi-GPU TensorFlow / PyTorch stack to **two CPU servers** – 10× cost reduction, equal or better accuracy. Shipped computer-vision prediction APIs and Elasticsearch-backed search for customer-facing cloud services.

INSTAR Deutschland GmbH (Waletech) Shenzhen, China
Chief Technology Officer
2 yr

Operate a **70+ bare-metal and VPS fleet** (Linux, CentOS / Ubuntu) serving internal tooling and customer-facing web services. Orchestrated all workloads on **HashiCorp Nomad + Consul**: self-healing, auto-scaling, one-PR onboarding for new teams. Standardised CI/CD on self-hosted **GitLab**: OSS source → Docker container → Nomad deploy → Zabbix / Grafana observability. DevSecOps: CVE response, security monitoring, access-control hardening across every customer-facing service.
