What I'm looking for

I’m looking for a challenging Embedded Systems Engineering role where I can apply Embedded Linux, RTOS, and secure IoT design to build reliable long-range edge solutions and solve real-world firmware and hardware blockers.

I’m an Embedded Systems Engineer with around 3 years of experience in low-power IoT design, communication protocols, and embedded system integration. I build and optimize firmware and embedded Linux solutions on STM32MP1 MPU and Raspberry Pi, and I’m hands-on with C/C++ for STM32 and ESP32.

I’ve delivered measurable improvements in device performance and reliability—boosting battery life from 30 days to 1000+ days, extending LoRa range from 200m to 16–20km line-of-sight, and implementing secure over-the-air firmware upgrades by migrating from HTTP to HTTPS. I also enjoy the full stack of hardware and software work, from RF hardware/antenna selection and RF layout to PCB design and integration; and I bring a founder’s mindset through Grelien, an open-source autonomous agriculture IoT initiative combining embedded systems, IoT communication, and machine learning.
