At a confidential client, I developed a native C library for Android and iOS that supports hardware-backed keys, key and device attestation, and app integrity checks. I implemented secure session and cryptographic identity logic, tested it on real hardware, and addressed findings from about 10 rounds of independent security review.
At Avisto Eastern Europe (Advans Group), I integrated security monitoring into STM32N6 firmware and deployed int8-quantized LSTM and SRU models on ESP32 devices. The SRU ran about 4.5 times faster than the LSTM within a 240 KB RAM budget, and the results were published in a co-authored paper.
