Hi Let’s be honest: nobody likes the HLK. It’s a beast. But I’m the rare kind of developer who actually knows how to tame it, get those green checkmarks, and get a driver signed without losing my mind. I am a senior systems engineer who treats it like a morning horoscope. I have spent the last 6+ years straddling the dangerous line between User Mode comfort (C# services/CLIs) and the Kernel Mode wild west (C++/WDK). Here is why I’m the right fit to help Hone squash jitter: - I write KMDF drivers that respect IRQL <= DISPATCH_LEVEL. I handle IOCTLs, memory mapping, and synchronization safely so we don’t BSOD your users mid-match. - I live in WPA/PerfView. I’ve spent weekends hunting rogue DPCs and ISRs that were ruining 1% low FPS. I don't guess; I trace. - I don't just write the .sys; I build the C# orchestration, the Windows Service, and the IPC to make it actually usable for the gamer. - I know how to optimize a system without looking like a rootkit. Keeping players unbanned is just as important as keeping them fast. I am ready for the C++ CLI coding test (bring it on). Let’s make some PCs faster and hopefully get some winner-winner chicken dinners while we’re at it. Cheers, Nam

Driving innovation for high-performance Windows experiences—your challenges are my next achievements. The technical requirements for your project include designing and delivering production-ready Windows applications and kernel drivers in C++ and C#, orchestrating driver signing/distribution, deep ETW profiling and telemetry parsing, robust user-kernel communication, and troubleshooting via advanced WinDbg/IDA/Ghidra techniques. I have over five years of professional experience building and shipping sophisticated Windows solutions, including low-level kernel drivers (WDK/KMDF/UMDF), advanced performance analysis automation, and user-mode orchestration, frequently bridging gaps between system diagnostics, HLK readiness, and seamless Win32/COM/WMI interop for gaming and performance tooling. I am passionate about delivering tooling that squashes lag, elevates system responsiveness, and offers crisp, developer-focused documentation, always with a clear and efficient investigation-to-implementation loop. My work style is autonomous and fast-paced, and I thrive turning fuzzy performance problems into measurable, actionable improvements. Real Reply. I look forward to your response. Thank you.

@VianRey1

When performance bottlenecks hide behind tricky kernel behaviors and driver quirks, it slows down your team and leaves gamers frustrated. Wrestling with HLK readiness, ETW traces, and those unpredictable device interfaces is costly when every update needs to be spotless and fast. You can expect clean, production-ready drivers and services that sail through HLK, surface actionable telemetry, and make your performance tooling rock-solid for all those real-world gaming sessions. First, I dive into your current kernel and user mode stack to spot the root friction. Next, I streamline driver installs and ensure every HLK suite and ETW trace delivers clear, actionable data. Finally, I automate analysis to highlight issues like CPU stalls or DPC waits so your team focuses on real improvements. What’s your current biggest headache with driver readiness or performance tracing?

"For over 5 years, my role as a software engineer has revolved around developing high-performance Windows applications and services using C# and C++. I've not only shipped drivers using the WDK, but I'm also adept at tackling various challenges that arise during the process such as IOCTLs, synchronization, and safe memory management. Interoperability across platforms has been one of my core strengths. My proficiency in Win32 API and other factors like COM, registry handling, services, and job objects will ensure seamless user↔kernel communication boundaries in your project. I'm equally at ease working autonomously which often results in swift delivery of production-ready code." "As an engineer, I not only build but also have a deep understanding of 'why and how'. This is where my experience with ETW/WPT truly shines. I'm highly familiar with capturing/reviewing ETL as well as using WPA/xperf to troubleshoot performance issues. My experience extends beyond just the development aspects and includes running HLK suites, diagnosis of failures & packaging for submission. Familiarity with tools like PresentMon/CapFrameX-style metrics enhances my parsing and analysis skills for performance & gaming telemetry data. My exposure to kernel debugging, reverse engineering with tools like WinDbg/IDA/WinDbg is another valuable addition to assist in clarifying behavior when needed." "Hone's remote work culture coupled with the opportunity to impact the gaming industry on such a tangible level greatly appeals to me. Being an avid gamer myself, I understand the significance of tailoring systems to deliver seamless experiences for users. Consequently, making PCs faster and smarter for gamers everywhere through this project aligns perfectly with my passion for gaming and optimizing system performance. I'm all set to take your technical vision forward while weaving in my creativity and efficiency in implementation. Let's talk more about how we can make a difference together!"

Hi there, Are your drivers strictly KMDF or do any parts rely on UMDF for user-mode fallback behavior? For HLK readiness—do you already have a working driver INF and package layout, or should I prep from scratch? Real reply. I’ve built and shipped both kernel-mode and user-mode components for performance tools and system tuners. In one project, I wrote a C++ KMDF driver to monitor GPU load with IOCTL endpoints, and layered a C# CLI + service stack on top using P/Invoke to cross the boundary safely. I’ve worked with ETW (xperf, WPA, trace relogging), automated bottleneck scans across DPC/ISR stalls, and debugged install/update issues with verifier and HLK test suites. Also familiar with WinDbg, Ghidra, and handling test signing + attestation builds end to end. Happy to jump in fast and ship clean Windows internals code that scales to thousands of gamer setups. Let’s eliminate some stutter together. Hope to discuss more on chat. Best, Ivan
