What I work on

  • Embedded platforms: I work from board bring-up and kernel/RTOS integration to C/C++ components and application services.
  • Production engineering: At Nokia, I worked on 5G RF/L1 and SoC platform software, including channel estimation, hardware integration, target debugging and Python validation tools. At Etteplan, I developed Python and Robot Framework test automation for embedded systems.
  • Public engineering work: I contribute to Linux, Zephyr RTOS, U-Boot and DPDK, and build projects in C++ concurrency, ROS 2, Python services and AI-assisted incident investigation.

Tech Stack

  • Core: C, C++, Python and Bash; Embedded Linux, RTOS and real-time software.
  • Platforms and drivers: Yocto/OpenEmbedded, U-Boot, Device Tree, Linux IIO, Zephyr RTOS and ARM64 SoCs.
  • Integration and debugging: Hardware/software interfaces, GDB, JTAG, logs, traces, perf and ftrace.
  • Networking and applications: DPDK, NXP DPAA2, SONiC tooling, ROS 2, FastAPI and Docker.
  • Build and validation: Git, CMake, BitBake, Jenkins, GitHub Actions, Robot Framework and automated regression testing.
  • Additional work: RISC-V coursework and quantum-software contributions through Qiskit and D-Wave Ocean.

From Board Bring-Up to Application Software

My work covers the full path from board bring-up to application software. At the platform layer, I work with U-Boot, Device Tree, Yocto/OpenEmbedded, Linux kernel drivers and Zephyr RTOS sensor interfaces. Above that, I develop C/C++ libraries, real-time software, system services and the interfaces between components.

System design connects these layers: how data moves, where timing matters, how failures are handled and how the result is tested. My Nokia work provides the production foundation; my open-source and personal projects extend it into sensor drivers, ROS 2 integration, Python/FastAPI services and engineering tools.

Board-to-application software map showing hardware, alternative Embedded Linux and Zephyr RTOS paths, C/C++ real-time software, services and applications. System design, integration, debugging and validation span every layer.
View the full path from chip IP to board bring-up

From chip IP to board bring-up: silicon, board and software lanes with hands-on, exposure and upstream-context markers, and one issue traced across six layers from RF functionality and middleware through low-level SoC software, the SoC controller and PHY to the board interface.

My path started with RF middleware and moved down the stack to low-level SoC software, register-level configuration and SoC subsystem debugging, with exposure to silicon and board-level bring-up. Download the diagram.

Mainline commits · Patch archive · Mailing-list history

Zephyr RTOS Contributions

  • MAX30102 support: Added MAX30102 support to the existing MAX30101-family optical sensor driver. Merged.
  • INA237 sampling fix: Made triggered-mode sample_fetch wait for conversion readiness before returning data. Merged.

U-Boot Contributions

  • board/ge/common/vpd_reader.c: Corrected the errloc allocation in verify_bch() to use ecc_bits rather than the much larger data_length. Merged.

Quantum Computing Contributions

  • Qiskit PR #16590: Proposed a memory-safety fix for writes to uninitialized buffers in the transpile-layout C API. Open.
  • D-Wave Ocean SDK PR #453: Added Advantage2 to the SDK overview documentation. Merged.

DPDK / Networking Contributions

My DPDK work covers NXP DPAA2 bus and DMA code, including device-removal and error-handling fixes. This is part of my open-source work on the platform software behind high-performance networking.

View how DPDK supports data-center packet processing

How DPDK helps a data center: traffic passes through NIC receive queues, a DPDK user-space application and transmit queues to workloads. Polling, packet bursts, assigned CPU cores and local buffers can reduce overhead and improve capacity. My NXP DPAA2 fixes propagate device-removal failures through the DMA and bus layers so callers can handle them.

Technical background: DPDK poll-mode drivers and data center use cases. Download the diagram.
