Linux BSP · Device Drivers · ARM Cortex · Embedded C/C++
Embedded Software Engineer — drivers, BSP, and systems close to the metal.
I work on the software layer between hardware and OS — device drivers, BSP bring-up, I2C/SPI/UART protocols, and system validation. Currently at LG Soft India, shipping DDC/CI driver flows across ARM and Intel SoCs.

About Me
EE graduate who moved deep into embedded software
I studied Electrical and Electronics Engineering at Alagappa Chettiar GCET, Karaikudi, graduating in 2023 with a CGPA of 8.42. During that time I got interested in how software actually talks to hardware — so I went and trained specifically in embedded C, Linux internals, and ARM driver work at Emertxe, Bengaluru.
Since February 2024 I have been working as an Embedded Software Engineer at LG Soft India (contract via Duru Cooperation). My day-to-day involves DDC/CI device driver work over I2C, BSP bring-up on ARM and Intel SoCs, hardware debugging, and building validation suites that follow ASPICE practices. I also cut the app memory footprint from roughly 80% down to 10% through profiling and buffer lifecycle cleanup.
Driver DevelopmentDDC/CI over I2C, peripheral initialisation, interrupt-driven flows, firmware update state machines across ARM and Intel platforms.
Debugging & ValidationJTAG, GDB, Wireshark, Instruments — across Linux and macOS. Built conformance, calibration, and acceptance test suites aligned with ASPICE.
Memory & PerformanceMemory footprint from ~80% to 10% using profiling, buffer analysis, and lifecycle cleanup on embedded Linux applications.
Experience
Where I have worked
LG Soft India, Bengaluru · Contract via Duru Cooperation
- Write and maintain DDC/CI device drivers over I2C on ARM and Intel SoCs.
- Handle BSP bring-up and hardware interface debugging on Linux and macOS.
- Build validation suites for calibration, conformance, and acceptance flows (ASPICE-aligned).
- Reduced embedded app memory usage from ~80% to ~10% through profiling and buffer cleanup.
- Work inside Gerrit code review and Jenkins release pipelines across 10+ display variants.
Emertxe Information Technologies, Bengaluru
- Intensive training in embedded C/C++, Linux internals, system programming, and ARM Cortex-M driver development.
- Built projects including a bare-metal car blackbox (event data recorder), search optimisation, calculators, stack and tree data structures.
Projects
Things I built at work
LG Soft India · Dec 2025
LG AI Subtitles
Real-time subtitle generation on webOS TVs. I wired up a GStreamer audio pipeline into Whisper AI, wrote reusable Android control modules, and started a Flutter port for cross-platform reach. Also tracked down and fixed the memory bloat that came with the AI model loading.

LG Calibration Studio
macOS calibration tool for medical-grade monitors. Handled DDC/CI peripheral control over I2C, scalar firmware update flows, and built the acceptance validation suite for regulated display environments.

Car Blackbox
Bare-metal event data recorder on ARM Cortex-M — no OS, no abstraction layer. I configured GPIO, interrupt controllers, SPI and UART drivers from scratch, and managed event storage using a ring buffer.
