Talk & Demo · Flow Festival 2026
Flow Festival: Live AI Music Generation 🎤
I gave a talk about "Creativity and AI" at Flow Festival 2026 in Helsinki. Because it was a music festival, I had to compose music live on stage to earn my "artist" pass! I built an application orchestrating Gemini, Lyria 3, and Nano Banana 2 to generate original lyrics, synthesize audio tracks, and create album cover art in real time.

Ask plain English questions about housing prices and household income across Finland's 3,000+ postal code areas.

Kids AI · Safety Guardrails
Safe AI Voice Companion for Kids (Wasabisaurus) 🦖
Created for my kids (6 & 3 years old) so they could talk with AI safely. Standard AI apps lack proper safety guardrails for young children, so I connected Gemini with layered security filters, gave it a custom avatar co-designed with my kids, and let them pick its voice with Chirp 3 HD. Built bilingually in Finnish & Spanish, with an interactive bubble-popping minigame to keep children entertained during model response latency.
