Work Experience

Embedded Software Integration Engineer

2017 - PRESENT
AB Volvo
  • Developed application software for the paver machine that involved coding in C, input/output (I/O) configuration, unit testing, hardware-in-the-loop (HIL) testing, and debugging.
  • Involved in the development of base software by creating designs, coding in C++, and handling unit testing on the electronic control unit (ECU). Also contributed to functional safety metrics.
  • Worked on unified diagnostic services (UDS), ISO 26262, controller area network (CAN), and other device driver components.
  • Built and grew a team from scratch as part of my role.
  • Collaborated with colleagues and suppliers from Sweden, the UK, and Germany.
  • Deployed an ECU software worth $7,200 with no guidance while managing a team of 4-6 people.

Embedded Software Engineer

2015 - 2017
  • Analyzed the runtime environment (RTE) layer requirements and specifications of the AUTOmotive Open System ARchitecture, AUTOSAR, including software requirement specification (SRS) and software specification (SWS).
  • Designed the embedded C code for the runtime environment (RTE).
  • Developed the code of a tool to parse ARXML files and generate source and gear files based on the RTE configuration.
  • Presented the product to the client and earned the Wow Award for my contributions to the RTE design and development.

ECU Deployment Worth $7,200

Deployed and ECU by Removing the operating system dependencies to separate the base code from the existing software, including base software, real-time operating system (RTOS), and application software. Then, I filtered only the essential and minimal startup code. On top of this minimal code, I set up the unit testing environment in the hardware (HW) with the Cantata++ tool. This required skills and understanding of startup code, compiler and linker flags, C++14 features, and microcontrollers.

If we had contacted the supplier for this, it would've been billed $7,200. I conducted the entire process on my own with very minimal guidance.
