AI security engineer at Freelance building multimodal RAG applications and red-teaming production AI systems.

At Freelance, I assess AI applications for security and production readiness, and built a commercial multimodal RAG chat application with document ingestion, semantic retrieval, and image-based features. I also created Vela, a generative video production pipeline combining custom LoRA training with image-to-video and automated post-production.

At Gremi Media SA, I lead engineering for the rp.pl and parkiet.com newsrooms, where I designed and deployed internal LLM platforms and hardened the Kubernetes environment. My work in AI security builds on 18+ years in software engineering, including banking backends and web platforms, and I’m a Certified Offensive AI Expert (COAE) by Hack The Box.
