Straight to the solution

Senior student in Computer Engineering & Biomedical Engineering at Ankara University. I build Android apps that run AI on-device, with no cloud, no data leaks, and no compromises. My work spans scientific instrumentation (NFC potentiostats), on-device LLM inference (Gemma 3), and productivity tools, all published on Google Play under SensiStudio. I care about shipping real products, fast, and making complex hardware feel simple on a phone.
