Single Board Controller (SBC) – IPMC Firmware Development

• Reviewed schematics and configured pins for Cortex-M4 (NXP MK10); built SDK from scratch and setup MCUXpresso development toolchain.
• Identified hardware bug where SPI NVRAM MISO/MOSI lines were swapped; coordinated fix with hardware team, unblocking firmware development.
• Debugged MCU bring-up with hardware team, resolving reset signal issues causing initialization failures.
• Cross-reviewed 40G/100G Ethernet schematics against Intel reference design, flagging discrepancies; located NVM firmware and installed Linux dependencies to unblock interface initialization.
• Validated Ethernet interface up to 10G via JDSU; full 40G/100G testing constrained by available optical cable and test setup.
• Developed IPMC firmware interfacing Kintex/Artix FPGAs, ADCs, temperature sensors, SPI NVRAM, and GPIO interrupts with health monitoring and fault handling.
• Implemented IPMB communication and VITA-standard IPMI commands; reported board diagnostics to host processor over UART.
• Validated RHEL boot-from-RAM (Live OS/Squash FS) including filesystem preparation, initramfs generation, and GRUB boot configuration. PCIe Configuration & VxWorks Application Development
• Configured PCIe for a newly integrated Microchip PCIe switch using Microchip Chip Link tools and established NTB (Non-Transparent Bridge) communication.
• Assisted in PCIe NTB driver development and debugging on VxWorks.
• Developed and debugged VxWorks application features including log persistence and GPIO-based startup control.

MIL-STD-1553B Firmware for FPGA IP Validation

• Developed firmware on MPSoC to validate and demonstrate in-house MIL-STD-1553B FPGA IP.
• Implemented BC-RT, RT-BC, RT-RT, broadcast, and Monitor Terminal (MT) modes to capture and analyze multi-channel bus traffic for protocol verification.

Application Development Projects

• Developed mobile and desktop applications for e-commerce, OMR, and PDF/VDP systems (UI, APIs).
• Integrated third-party modules and validated end-to-end flows via integration testing.
