As a senior contributor of the GPU software team, I was involved in building expertise across the Vulkan, Compiler, Compute, System Software, and QA verticals. Significant contributions to the GPU driver software stack in UMD and KMD for AMD GPUs (RDNA1/2/3/4), integrated into Exynos SoCs for flagship and mid-segment Android phones. Played a key role in the successful productization of Samsung Galaxy devices: S22, S23, S24, A55 (currently in the market), and ongoing development for S25 and A56.Expertise in user-mode Vulkan and kernel- mode driver development for Android 14 and Android 15 platforms. Experience with Pre-silicon bring-up on emulation platforms like Velochi and ZEBU, as well as post-silicon bring-up (in Korea) leading to product release, covering the full software development life cycle. Worked in power and performance improvement DVFS, AFM, HTU, IFPO drivers I developed Binary logging and integrated static analyzer. Vulkan extension Dynamic state3, DRM format modifiers, CTS I worked in Vulkan, libDRM and kernel mode driver refactoring in order to improve code coverage, performance and easy maintenance. I work with QA team and other cross functional team to make sure 100% CTS run in CI/CD bench and debugging. I excel in delivering software solutions that are 100% compliant and meet KPIs, while effectively collaborating with global teams based out in Korea and the US

Technical Club & Culture Head: Sessions on cutting edge and emerging technological topics. Organize company events, employee development programs and outdoor fun activities to keep motivation and enthusiasm

I developed video firmware for the iMX8 QuadMax (ARM 64 bit based) and Development Vehicle SOC. That includes HEVC decoder and Multi- Standard Decoder firmware for QuadMAX video CPU. I did Pre and Post silicon bring up of multi-standard video decoder on FPGA and SoC and firmware development

US based Content Networking SoC startup Zenverge Technologies, which later got acquired by NXP. As a Principal engineer, involved in many aspects of the Linux based Multimedia SoC product development for Home Media Gateways. Developed low level embedded video transcoding firmware for the SoC which was based on MoCA technology. Its a broadcast multi-standard video trans-coding hardware accelerator-based chip, which supports H.264 to MPEG2 to H.264 video transcoding with frame rate controller (FRC) using FreeRTOS based scheduler. Audio MP3, HE-AAC, AC3 audio, SRC transcoding firmware was supported.

Designed and developed the complete software stack of events-based video recording using CCTV on ARM-based Access Control System and successfully deployed as a product NextAXS123 into market. Developed RTSP library interface, board, buffer management for video recording on events, SQ Lite database, Mail server, and Overall system integration

Developed Linux based BSP bring-up on ARM9 based Sanyos development board, including Uboot, Linux kernel and various device drivers. I did design and develop a low power 24-bit & 32-bit fixed point VLIW DSP and SIMD DSP. Involved in the analysis of CPU performance including instruction execution, holes in bit encoding of ISA, instruction generation by C compiler, functional units of CPU, ISA performance for audio codecs etc. Ported various speech encoder and decoders Speeks decoder, Pulcode encoder and decoder, MP3 decoder, WMA decoder, H264 decoder using C and Intrinsic functions SOC for Ultra Low-Profile Voice Recorder (14A-Next Generation) Audio device driver development includes design, ADC, DAC, Volume, Mute, Analogue filer, digital filer, Damp, ALC, PCM interface, BEEP, pause, play, record, stop. Software integration of PULCOD, SSBC, SPEEX, OGG, and device driver with Toppers JSP RTOS.

I developed On-Screen Display Menus for various languages for CRT TVs and worked with various customers I designed and developed Space Vector Modulation and Sinusoidal PWM software to control 3-phase AC induction motor and bare metal device drivers (Remote and other)

Developed Telephone-based product including circuitry and assembly language software development using 8051 series microcontrollers. Developed ADPCM and Noise cancellation implementation using Code composer studio for TI TMS32054x processor
