Punya Mittal

AI/DSP lead for Team Diet Code (VIT Chennai). I build edge-native sensing systems that turn commodity phones into lab-grade instruments. Flagship AquaScope / SMRITI AQUA is a vibro-acoustic moisture scanner: 80Hz-16kHz chirp @48kHz, FFT deconvolution, LDA anomaly score, on-device Qwen Ask. Field-validated 32 locations / 313 scans (69.1% balanced accuracy, +24.1 pt moist lift). Kotlin + KissFFT. Repo https://github.com/Punyamittal/AquaScope Demo
