Summary
👤
Senior🎓
Top SchoolJuha Niskanen is a senior software specialist with 14+ years building and debugging low-level systems, RTOSes and SoC integrations across embedded, mobile and EDA domains. He brings deep concurrent programming expertise and hands-on mastery of C, assembler and multicore pthreads across platforms from Linux and Plan 9 to ThreadX and Nucleus. At companies including Nokia/Microsoft and Haltian he led kernel-level development, driver integration and root-cause debugging of elusive chipset and baseband issues. An active contributor to the NuttX/PX4 ecosystem, he has added I2C drivers and MCU support that improved stability for real-world embedded products. Juha pairs strong analytical instincts with a track record of fixing problems that stalled others, and prefers senior engineer, technical lead or architect roles focused on low-level C/assembler work. He is also involved in regional tech outreach through the Polestar.fi initiative promoting investment in Oulu.

Jan 2020 - Apr 2024
Apache NuttX is a mature, real-time embedded operating system (RTOS)
Role in this project:Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:8 reviews, 50 PRs, 73 comments in 4 years 4 months
Contributions summary:Juha contributed to the development of an embedded real-time operating system (RTOS) by implementing and fixing threading and mutex-related functionalities. Their work includes fixing inconsistencies in mutex handling, enabling support for features like recursive mutexes, and addressing potential memory-related issues in low-power modes. Additionally, the user added support for new hardware components like the STM32L15XX, the addition of features, and performed some maintenance on the drivers.
