Atul Raj

I am part of the Core Computing Group as a Debug & Validation Engineer, where my primary responsibility is ensuring the stability and performance of Intel CPUs for Laptops, Desktops, and Workstations. I work across multiple platforms and am often engaged as a horizontal resource for complex debug and validation tasks.

Key Responsibilities:

• Debug and resolve issues reported by the execution/QA teams, including: Power Management Controller (PMC) bugs: Deep dive into hardware-software interactions to identify root causes. Memory and OS crashes: Analyze BSODs and bugchecks to trace underlying CPU or platform issues.CPU Core State Machines: Understand and validate implementation against architectural requirements.
• Boot & Reset Hang Debug: Lead major debug efforts for boot and reset hangs, including analyzing entry and exit sequences, and performing IP-level debug to isolate issues across different CPU blocks and reset/boot phases.
• Issue Isolation: Investigate any reported issue, isolate it to a specific component or “ingredient,” and escalate it to the concerned team. This involves debugging soft/hard hangs such as PMC hangs, CATERR, and MCA errors reported by core and uncore logic.
• Lead teams on several occasions, delivering builds on time and achieving planned milestones.

Tools & Technologies: C++, Visual Studio 2022, JTAG Debugger, WinDbg, JIRA, Git, Perforce

• Developed Class2/Class3 Casino Slot Games in Unity & C#.
• Optimized Linux-based slot games, achieving high FPS performance on low-end hardware through threading, CPU–GPU optimization, and memory tuning.
• Delivered commercial-ready casino games through code and math model optimization.

• Designed and developed casino slot and lottery games end-to-end using Unity & C#.
• Implemented Return-to-Player (RTP) models into game flow based on math-driven design.
• Built reusable modules, animations, prefabs, and sound systems to accelerate game development.
• Migrated legacy slot platforms to run seamlessly across Windows/Linux systems.

• Developed and debugged casino and lottery game software, including game logic, randomization, and data validation; collaborated with design, math and QA teams to implement features, ensure game fairness, and maintain production-ready builds.

• Intel Project – Power Management Validation (8 months): Validated Windows device drivers and power management features (ACPI, Connected Modern Standby) for Intel Gen9 processors. Debugged platform issues using JTAG, WinDbg, signal analyzers, and BIOS logs.
• VeriFone POS Development (1 year): Contributed to POS software module development for VeriFone payment devices, including bug fixes, feature enhancements, and making it robust in OOP.
