Back to original languageAbout Martin
Are you looking for an experienced architect to bridge the gap between cutting-edge Generative AI and highly available cloud infrastructure? With over 10 years of experience in software development and operating high-traffic platforms in the media sector, I support companies as a specialized Senior Engineer in overcoming business-critical bottlenecks.
My focus is on the productive implementation of AI systems that not only work in the test lab but also scale stably, data-protection-compliant, and securely within your infrastructure.
What I can do for you:
• AI Engineering & Agents: Integration of open-source LLMs (via vLLM, Ollama) and development of autonomous AI workflows with the Google Python ADK.
• Cloud & DevOps Infrastructure: Building, scaling, and hardening Kubernetes clusters (k8s) and automated deployments using Terraform on a Linux basis.
• Web Security & Performance: Securing your applications against DDoS and optimizing global caching strategies via Cloudflare.
• Backend Architecture: Performance tuning of highly concurrent PostgreSQL databases and robust services in Python and C#.
Through my many years of experience as a developer, I understand complex system architectures at first glance. I am available for highly specialized part-time engagements, pragmatic troubleshooting, and the clean automation of your systems.
