Migration of Design Engineering Software (DES) on ARM based Linux platform.

- Systems Engineering Mentorship: Mentor undergraduate teams on Linux build systems and Yocto-based cross-compilation, guiding ARM-based projects and diagnosing complex build/runtime dependencies. - Platform Administration: Serve as the technical administrator for the Watermark institutional platform, managing faculty data workflows and ensuring system compliance for the College of Business. - Operational Strategy: Support the Department Director in executing strategic academic initiatives, utilizing data analytics to optimize administrative processes and student success metrics.

- Search System Optimization: Contributed to the optimization of Falcon Finder, the university’s central research discovery tool, improving search query accuracy for books, journals, and academic articles. - High-Performance Computing (HPC) Support: Managed and maintained high-performance workstations dedicated for Machine Learning training and simulation tasks, ensuring GPU availability and system stability for research students. - IT Asset Management: Administered the Alma Library Services Platform (LSP) to manage digital and physical assets (laptops, hotspots), performing hardware troubleshooting and diagnostics for student devices. - Technical Support: Provided Tier-1 technical assistance to university patrons, resolving connectivity issues and software configuration errors on borrowed hardware.

Core Architecture & Framework Design (C++ / WPEFramework) - Protocol Architecture (Firebolt): Architected the Firebolt adapter in C++, enabling 300+ apps (Netflix, YouTube) to interface with the Thunder (WPEFramework) TTS service. - Accessibility Middleware: Optimized RDK-AT to bridge WebKit/ATK with the TTS backend, onboarding 200+ ARIA-labeled apps via precise DOM focus mapping. - OS Migration: Led the architectural migration of Voice Guidance from legacy RDK-V to EntertainmentOS (RDKE), ensuring zero-downtime stability. Audio Systems & Smart TV Ecosystem - Unified Audio HAL: Engineered a hardware-agnostic audio layer for Realtek, Broadcom, Amlogic, and MediaTek SoCs, abstracting dependencies for a unified codebase. - Smart TV Integration: Deployed Voice Guidance on Sky Glass, Xumo (ES1/XiOne), and partner OEM panels (Hisense, Sharp, Element, Cello, Westinghouse). - Audio Ducking: Implemented system-level audio mixing using GStreamer, managing dynamic pipelines to auto-lower media volume during TTS playback. Global Strategy, Quality & Compliance - QA Strategy: Devised the master test plan for multi-region validation (US/UK/EU), ensuring feature parity across Apache (2K/4K) reference boards and commercial devices. - Global Rollout: Directed Voice Guidance launch in UK, Italy, and Germany (EAA mandates) and maintained US ADA compliance. - Reliability: Resolved 100+ concurrency/memory defects using GDB, Valgrind, ASan, and TSan, increasing test coverage from 10% to 80%.

Core Platform Engineering (X1 & Flex Ecosystems) - WPE-WebKit Engine Mastery: Maintained and optimized the C++ source of the WPE-WebKit browser engine, the primary runtime for the X1, Flex 1, and Flex 2 platforms, supporting a catalog of 300+ OTT apps (Netflix, YouTube, Peacock) across tens of millions of devices. - Upstream Open Source Contributions: Identified and upstreamed critical stability fixes to the official WPE-WebKit repository, specifically resolving complex race conditions, deadlocks, and engine-level crashes. - Memory & Concurrency Hardening: Debugged kernel-level heap fragmentation and memory leaks in multi-threaded environments using Valgrind and GDB, significantly reducing OOM (Out of Memory) incidents. Multimedia Architecture & Strategic Integrations - Streaming Pipeline & DRM Orchestration: Architected and tuned GStreamer/FFmpeg plugins for high-fidelity AV synchronization. Enforced strict MSE/EME compliance, integrating and debugging multi-DRM systems (Widevine, PlayReady) for secure, commercial-grade 4K/HDR streaming. - High-Profile Integration: Engineered the platform-level integration for Nintendo services and third-party gaming SDKs, optimizing graphics rendering and input handling for the X1 ecosystem. - Next-Gen R&D: Developed a Hand Gesture Control System PoC for the Sky Llama platform, bridging computer vision sensor data with the browser’s input layer for touchless UI navigation. Silicon-Level Optimization & Diagnostics - SOC-Specific Optimization: Validated and tuned performance across Broadcom and Realtek chipsets, managing hardware-accelerated decoding for the full device fleet: - Modern Platforms: Sercomm XiOne, Sky Llama Panel, Sky STB, Technicolor Xi6. - Legacy Platforms: Arris XG1v3/v4, Pace XG1v3/XG2v2. - Deep-Dive Diagnostics: Leveraged system profilers and custom telemetry to resolve 80% of playback-blocking issues and optimize web app local caching, reducing cold-boot latency and network I/O.
