Work Experience
Freelance Embedded Software Engineer
Fjorden
- Developed Fjorden Grip firmware and bootloader using Zephyr RTOS.
- Exposed device functionality over BLE interface, allowing official and unofficial mobile applications to access and modify settings and features.
- Implemented secure device firmware upgrade (DFU) to allow customers to update their devices using mobile applications.
- Expanded device battery life to approximately six months on standard coin cell battery by utilizing nRF52 SoC low power features.
Freelance Embedded Software Engineer
Sense
- Developed and tested nRF52 firmware using Zephyr RTOS in C programming language.
- Optimized the firmware for low power operation resulting in battery-powered mode to last for approximately eight months of continuous operation.
- Implemented BLE mesh networking between peer devices, allowing simpler on-site installation with minimal use of data and power cables.
- Used oscilloscope, logic analyzer, and multimeter to trace and debug board-level issues, thus shortening the time between board iterations.
- Oversaw product prototype installation and guided workers on how to optimize the system as a whole. Documented and streamlined the entire process to reduce the time and complexity of future deployments.
Embedded Software Engineer
Ericsson Nikola Tesla
- Collaborated on the development, testing, integration, and delivery of essential features that impacted WCDMA, LTE, and NR networking modes of the radio interface control software.
- Pioneered on multiple product-wide codebase refactoring, improving testability and reducing complexity, which contributed to a 70% fall of bug reports over a period of three months.
- Designed and implemented a custom containerization engine used for efficient virtualized component testing of critical software modules.
- Transferred knowledge and experience by performing extensive code reviews.
- Held multiple department lectures to educate coworkers about best practices.
- Performed technical screening for hundreds of job candidates.
Embedded System Engineer
Startup Client
- Provided advice on which features to focus on during early product prototyping to maximize investment in the company.
- Designed and constructed a product prototype embedded device for potential investors and partners.
- Implemented BLE, GSM, and WiFi communication interfaces in order to allow the official mobile application to connect and access device functionality.
Software Engineer
Trovicor
- Improved deep packet inspection engine capabilities by designing and implementing multiple classification and extraction algorithms.
- Expanded the organization's internal knowledge base by reverse engineering over 20 application-level network protocols.
- Performed targeted network traffic interception in a controlled environment.
