After several years in the automotive industry, I moved into sensory analysis — an experience that led me to master Python and data analysis, then to adopt Rust. Passionate about AI, I noticed that the RAG market was missing a solution that was both truly modular and genuinely secure. With two specialist engineers, we built Lexiane from scratch to meet exactly that need. Starting from a blank page was a deliberate choice: to build natively for the strictest constraints, where existing solutions can only try to adapt.
