Embedded Firmware Engineer @ Samsung | PLDM Type 5/6 • Redfish RDE (BEJ) • OCP Firmware Recovery | MCTP • SMBus/I2C • CXL | C, ARM

About

I’m an embedded firmware engineer with 3+ years at Samsung, writing C firmware for ARM-based CXL devices. I like owning a feature from the spec to the silicon: reading the requirements, designing the layers, implementing state machines and interrupt handling, then validating in simulation and on hardware. What I’ve built: • PLDM Type 5 firmware update: all mandatory commands, a custom command, a seven-state update machine and timeout handling • PLDM Type 6 Redfish Device Enablement: schema and resource-tree design, BEJ encoding/decoding, vendor-defined commands, multipart transfer • OCP firmware recovery: boot flows (flash-based, flashless, streaming) and MCU–Caliptra integration, with hardware IP validation and test cases • DCU BIST framework: a 16-instruction ISA and default BIST algorithms for DDR4/DDR5 testing Skills: C, ARM architecture, MCTP, SMBus/I2C, CXL, Redfish, Trace32, QEMU, FPGA.

Associate staff engineer at Samsung Semiconductor, Mar 2025 - Present · 1 yr 9 mos, Bengaluru, OCP Firmware Recovery: Analyzed the spec (MCU–Caliptra integration; flash-based, flashless, and streaming boot), validated hardware IP flows, and wrote test cases. PLDM Type 6 – Redfish Device Enablement (RDE): • Designed and implemented Redfish Device Enablement (RDE) for CXL devices over PLDM/MCTP/I2C. • Enabled BMC-mediated Redfish resource management without a device-side HTTP/Redfish server. • Developed mandatory RDE commands and vendor-defined dictionary management commands (VUCs). • Conducted unit testing and functional validation of RDE commands and workflows.

Senior Software Engineer at Samsung Semiconductor, Aug 2023 - Mar 2025 · 1 yr 8 mos, Bangalore Central Business District, Bengaluru, Karnataka, India, PLDM Type 5, Firmware Update: • Led end-to-end delivery of an out-of-band firmware update over sideband (PLDM over MCTP on I2C), letting the CXL device be updated without host or in-band dependency. • Designed and implemented an fw update state machine (download, verify, apply, activate, etc.) with timeout and error recovery, plus multipart transfer for large images. • Validated end-to-end with a BMC across update flows, command exchanges, and failure scenarios. Direct Control Unit (DCU) : • Analyzed DCU specifications and developed detailed design documents. • Implemented the 64-bit DCU Instruction Set Architecture (ISA) with 16 instructions to execute programmable BIST patterns. • Implemented vendor-defined commands and 7 default BIST patterns, including MARCH_X, MARCH_C_PLUS, and MARCH_MATS_PLUS, and implemented GIC interrupt handlers for errors. • Performed firmware debugging and validation using Trace32 (T32), executing 15+ test cases across BIST algorithms and interrupt scenarios.
