I am an independent researcher based in Naples (Italy) working at the intersection of geometry, design and mathematical modeling. My current line of work (“etaphi”) explores golden-ratio tetrahedral/disphenoid structures and a discrete 90° screw–similarity that yields a closed-form axial step (ηφ). I introduced the ANNA golden disphenoid model and the etaPhi constant, with symbolic derivations and numerical validation. I use the Wolfram Language for exact algebra, 3D visualization and reproducible checks. I publish open preprints with DOIs on Zenodo and welcome constructive feedback and collaboration.
