Senior🎓
Top SchoolDevendra Tewari is a Senior Staff Software Engineer with 21 years of experience designing and delivering embedded Linux firmware, kernel drivers and consumer electronics systems from RISC-V and Raspberry Pi to production IoT devices. Based in Aveiro, Portugal, he blends low-level C/C++ and device-tree expertise with higher-level Python, libcamera and Yocto/BitBake workflows, and has driven features across camera sensor drivers, firmware update tooling and Matter/connected-home integrations. He contributes to prominent open-source projects such as meta-raspberrypi and the Matter stack, where his work spans kernel/device-tree changes, libcamera integration and robust Wi‑Fi management. Known for solving platform-specific concurrency and build issues, he pairs deep hardware interfacing skills (MIPI CSI-2, I2C, SPI) with pragmatic system engineering and developer tooling experience. An unexpected thread through his career is frequent cross-domain delivery—from Windows UWP and Bluetooth firmware up to cloud-connected gRPC and MQTT services—making him effective at bridging firmware, application and integration layers.
