Top expert inEmbedded IoT Systems Development
Mahavir Jain is a Director of Engineering and embedded software leader with 13+ years building real-time systems, IoT products, and secure boot solutions. He brings hands-on expertise across the full stack—from bootloaders and BSP bring-up to multi-threaded applications, device drivers, and networking stacks like lwIP and Treck. At Espressif he has contributed to high-profile open-source projects (esp-idf, esp-protocols, esp-at), implementing flash encryption, anti-rollback, and networking fixes for ESP32 platforms. Comfortable with SoC validation, Palladium/FPGA setups, and ARM Cortex-M architectures, he also writes low-level C/assembly and debug tools workflows (GDB, OpenOCD, linker/ELF analysis). Mahavir’s background in hardware peripheral interfaces and USB audio/video hosts complements his security-minded firmware work, and he often surfaces non-obvious fixes like interrupt allocation and critical-section handling that prevent regressions in widely used SDKs. Based in Pune, he combines product-cycle ownership with sustained open-source impact on embedded ecosystems.
