Roman Leonov

- Leading a team of embedded firmware developers; - Security architecture building and developing with cryptography protection usage; - Defining and developing various proprietary security implementation of transport channels over different types of USB protocols (MassStorage, CCID, HID); - Performing advanced analysis and identifying weak sides related to security throughout devices code; - Creation and maintaining of products and code documentation for other developers.

- Firmware development for different USB devices: Proprietary RTOS core, HAL drivers (usb, uart, spi e.t.c) for Freescale, NXP, ST and Nordic microcontrollers; - Designed and developed different proprietary secure bootloaders within the requirements depending on products; - Designed and maintained production batches from 450K pieces and higher; - Designed and implemented an architecture of a modular system with uploading parts for devices to simplify maintenance of products and increase production speed.

- PCB's development for NFC smartcard readers and NFC usb tokens; - Designed and prototyped cases, milling (CNC mill machine), print (3D printer technology) and assembling; - Designed, tuned up and matched antenna circuits for NFC data transmitting; - Researched of metal surface influence on NFC data transmitting and proposed adaptive system with ferrite usage to decrease this influence. Adaptive system of matching circuit switcher in environment dependence was developed.

- Development remote controller system of antenna driver for student educational curriculum with distant client application over TCP/IP; - Development automatic frequency generator control unit in heterodyne part of GNSS receiver; - Have designed architecture for radio protocol to astronomical time delivering for 120 wearable devices; - Have participated in creation of portable device based on GPS tracking systems for pets and animals with error correction during GPS signal lost.
