About

I’m a postdoctoral researcher turned product-minded ML engineer focused on generative AI, LLMs and agentic systems. I translate cutting-edge research (transformers, VLMs, generative audio) into robust, production-ready solutions and enjoy leading teams from prototype to deployed product. I build generative and perception systems that move beyond papers into products. During my PhD (in collaboration with Honda Research Institute EU) I developed meta-ML methods for robot self-assessment in human-robot teaching scenarios — a practical lesson in reliability and real-world integration. In my postdoc at the National Institute of Informatics (NII) in Tokyo I extended this work to generative AI: training 2D latent audio maps with VAEs to condition transformer-based audio generation and combining object detection (YOLO-style) with multimodal LLMs (GPT-4V) to create flexible perception frameworks for autonomous drones. My strengths lie at the intersection of deep technical expertise and pragmatic product thinking: selecting the right models, building robust evaluation and explainability pipelines, and shipping reproducible systems. I’m especially interested in agentic interfaces and LLM-driven automation that augment human workflows rather than replace them. Open to CTO/co-founder or technical lead roles where I can help turn generative AI research into impactful products.
