Between two chapters in Product Design, I pursued a personal creative project: documenting ocean life through cinema to raise awareness about marine conservation. Self-taught in cinematography, editing, color grading and screenwriting, I invested in cinema-grade equipment and started producing short films: solo, self-funded, from scratch. In 2 years: → Produced 3 underwater short films, selected in 32 international film festivals (Oceanic Global, Neum, Sea Film Festival, San Diego Underwater) → Won 11 awards including Best Short Film, Best Cinematography & Best First-Time Director → Screened "The Cosmos Beneath" at the United Nations Ocean Conference (UNOC3, Nice) → Created 90+ short-form videos: 1.7M+ total views across Instagram, YouTube & TikTok This project continues as a personal side endeavor alongside my Product Design work. It reflects the same mindset I bring to design: autonomy, creative problem-solving, storytelling, and delivering quality from zero to one.
