  - Added remote device management feature into IoT devices using the LwM2M protocol. The LwM2M protocol enables the device to be managed and monitored remotely through LTE connection. - Designed and developed a message authentication module, using time-based OTP to enhance security for remote device access. - Redesigned existing Firmware-Over-The-Air (FOTA) systems, as a lightweight event-driven interfacing system and low-level functionality. Integrates the FOTA with device management system. - Conducted comprehensive software unit and integration reliability tests to ensure robust performance. Show less

  I was tasked to developed an IoT power meter for photovoltaic cells. I have delivered several contributions to the product development: - As a sole embedded software developer, I am responsible to design an embedded system architecture aligned system specifications for real-time power monitoring of photovoltaic cells. This includes microcontrollers selection. - Constructed a foundational prototype to visually illustrate system concepts to colleagues for futher development (PCB, casing, electrical connectors, etc.). - Created a library to interface with the power meter sensors and developed calibration software for accurate measurements based on UART. - Established a network interface layer enabling interchangeable internet connectivity through GPRS, WiFi, or wired Ethernet options. - Devised a custom WiFi based devices provisioning, streamlining initial configuration for WiFi SSID, Password, and GSM APN. - Demonstrated rapid development by delivering a functional prototype within a 5-month development period as a sole embedded software engineer in the team.

  As an embedded software engineer, I was tasked on the development of Hardware Abstraction Layers (HALs) and low-level libraries tailored for custom System-on-Chips (SoCs) IP based on ARM Cortex-M3 IP. The results of the development process is HALs catering to hardware timers, GPIO, SPI, and I2C functionalities. Furthermore, these HALs are extended into an embedded framework, optimized for embedded C++ by using object-oriented programming.
