What I'm looking for

I seek roles building AI-driven, privacy-focused web and cloud solutions where I can own full‑stack development, DevOps and marketing integration within collaborative teams that value technical autonomy and measurable results.

I am a versatile IT specialist with over 10 years' experience in web development, AI-driven software and cloud computing.

As a freelancer and founder, I deliver full‑stack solutions using WordPress, Shopify, React and custom APIs. I build privacy‑conscious AI and LLM integrations for clients and projects in Germany.

I design and maintain CI/CD pipelines and cloud infrastructure using Docker, Kubernetes, Terraform and AWS, and I streamline development with GitHub and automated workflows.

I combine technical delivery with marketing expertise—SEO/SEM, content and ads—to increase visibility and conversions. I seek projects and teams that value ownership, privacy and measurable impact.
