Cloud-Native Architecture & Kubernetes
Expertise in designing and delivering large-scale cloud-native platforms using Kubernetes, Docker, Helm, Rancher, K3s, IBM Cloud, and AWS. Proven delivery of a world-first disaggregated access network platform spanning approximately 900 locations for a major telecommunications carrier.
Identity & Access Management
Deep knowledge in designing distributed role-based access control systems covering network equipment, Linux servers, Kubernetes clusters, and internal APIs. Proficiency with LDAP, Keycloak, OIDC, OAuth 2, TACACS+, HashiCorp Vault, and RBAC frameworks.
AI-First Knowledge Management & LLM Integration
Design and implementation of AI-first knowledge management systems using LLM Integration, RAG, Vector Databases, Knowledge Graphs, MCP Protocol, and Agentic AI. Development of semantic knowledge graphs and autonomous AI guidance agents for large-scale transformation programs.
Infrastructure Automation
Automation of complex infrastructure using Ansible, Terraform, and CI/CD pipelines with GitLab CI and Jenkins. Design of fully automated and reproducible VMware/vSphere environments and zero-touch provisioning workflows.
Data & Observability
Implementation of centralized logging and monitoring solutions using PostgreSQL, Redis, Kafka, Prometheus, Grafana, and Graylog. Experience building observability stacks for both legacy and cloud-native environments.
High-Performance Packet Processing & Network Architecture
Feasibility studies and architecture definition for carrier-grade lawful interception platforms, including 10G/25G/100G throughput analysis and compliance baseline definition for high-performance interception systems.
Programming & Scripting
Proficiency in Python, Bash, Go, C/C++, JavaScript, and Node.js for automation, tooling, and system-level development, including contributions to the Mainline Linux Kernel.
Distributed Systems & Microservices Design
Architecture of distributed systems with a focus on high availability, fault tolerance, legacy migration, and API design using REST API, OpenAPI, gRPC, and JSON Schema.
DevOps & CI/CD Pipeline Design
Design and implementation of automated CI/CD pipelines using GitLab CI, Harbor, Jenkins, and Ansible, executing jobs directly inside Kubernetes for streamlined software delivery.

Projekthistorie
Designed and implemented an AI-first knowledge management system to capture, structure, and retrieve technical knowledge across a multi-year, multi-vendor transformation program. Built ingestion pipelines using LLMs, designed semantic knowledge graphs with RAG-based retrieval, developed AI guidance agents, and created autonomous agents for daily note generation and knowledge reconciliation.
Architect for a world-first disaggregated access network platform replacing legacy infrastructure with a greenfield Kubernetes-based distributed platform spanning approximately 900 locations. Responsible for end-to-end system design, technical decision-making, and cross-vendor coordination. Designed a distributed RBAC system, architected a carrier-grade lawful interception platform, designed zero-touch provisioning workflows, and coordinated 50+ engineers across 4 international vendors in a SAFe environment.
Conception and implementation of a highly automated on-premise Rancher Kubernetes platform serving as a 3-stage development and production environment. Designed fully automated VMware/vSphere infrastructure using Ansible, built a centralized logging solution based on Graylog stack, implemented identity and access management with Keycloak, and designed automated CI/CD pipelines with GitLab and Harbor.
