I am working as an embedded software engineer.

Recently I finished these projects:
- Hospital bed software with 4 motors, 3 remotes, LCD touch screen, weighting system, position control, high current protection.
- Motor test system software with sensors, RS232, RS485 which can let users do settings and see results of multiple test environments from the center.
- Bootloader with AES128 encryption.
- Code uploader which reads data from SD card then sends to bootloader with AES128 encryption.
- External loader which lets users program external flash memory.
- Bare metal drivers which consume much less space in flash memory.
- Door lock system with fingerprint and keypad which also lets users lock or unlock doors with mobile phones by using Bluetooth Low Energy(BLE 5.0). 

- Many Windows desktop apps. 

Specialties: C, C#, desktop apps, bare metal coding, Git, MySQL, STM32, NRF52832, Bluetooth Low Energy (BLE 5.0), SPC58, Functional Safety, Multicore, UART, SPI, I2C, ADC, CAN.
