What I'm looking for

I'm looking to build reliable, high-performance, power-efficient embedded systems through low-level firmware, hardware-software co-design, peripheral drivers, and real-time logic.

I'm building low-level firmware and hardware-software systems at H2LOOP AI, including Nordic PPK2 integration for BLE optimization and low-power use cases.

At H2LOOP AI, I've brought up STM, NXP, and Microchip boards and built AI-powered CLI workflows for firmware flashing, debugging, and hardware validation. I've also integrated Saleae logic analysis and oscilloscope control through API and SCPI communication stacks.

At Articulus Surgical, I led development and debugging of synchronized actuator-control systems for robotics, using interrupt-driven real-time firmware and deterministic event handling. I also contributed to subsystem integration, filter circuits, and system validation.

I've developed STM32 power-electronics firmware, wearable and consumer-device software across AVR and ARM platforms, and LoRa-based STM32F4 telemetry nodes for early landslide detection.
