Windows Driver Consulting

Hire a Windows driver consultant who has shipped kernel code for 20+ years.

Joya Systems provides Windows driver consulting to companies that need kernel-level expertise but do not have it in house. If you are searching for a Windows driver consultant because a driver is crashing in production, because you need a new device driver built from scratch, or because you simply need help developing a Windows driver and getting it certified, you are in the right place. Our engineers have spent more than two decades writing, debugging, and reviewing kernel-mode and user-mode drivers across every major Windows driver model.

Driver code runs in the most privileged layer of the operating system, where a single mistake produces a Blue Screen of Death rather than an ordinary error dialog. That makes the cost of inexperience high and the value of a seasoned consultant correspondingly large. We bring hard-won knowledge from hundreds of shipped projects so that yours is delivered on time and stays stable on your customers' machines.

When companies hire a Windows driver consultant

Most of our consulting engagements fall into one of a few situations. Some teams have an application or hardware product that needs a kernel component they do not have the specialized skills to build. Others have an existing driver that is causing Blue Screens, hangs, or performance problems on customer systems and need it diagnosed and fixed quickly. Still others have working driver code but want an expert second opinion — a code review or architecture review — before they commit to shipping. And some need to bring an older driver up to current standards: 64-bit Windows 10 and 11 support, Driver Signature Enforcement, and passing the Windows Hardware Lab Kit. Whatever the situation, our role is to act as an extension of your team and get the driver problem solved.

Why work with Joya Systems

Depth of experience is what separates a Windows driver consultant who can ship from one who cannot. Our engineers have roots in the lowest levels of systems software, including time spent building one of the industry's most respected kernel-mode debuggers and years of daily work with SoftIce and WinDbg. We have analyzed thousands of crash dumps, often pinpointing a root cause from nothing more than a crash offset and a stack trace. That experience means we diagnose problems faster, write more reliable code from the start, and avoid the subtle kernel pitfalls — use-after-free in pool allocations, race conditions between IRQLs, improperly validated IOCTL input — that turn into customer escalations and security vulnerabilities months later.

How a consulting engagement works

An engagement begins with an initial technical consultation to understand the problem and scope the work. For new development, we review any existing specifications, hardware documentation, or legacy code. For debugging, we receive crash dumps or a description of the failure and identify what additional diagnostic information is needed. We then provide a written estimate covering the work, timeline, and deliverables. Work proceeds iteratively, with regular progress updates and early delivery of testable components, and concludes with the delivered driver or analysis, a clear explanation of the changes and the reasoning behind them, and a discussion of any follow-on work. Contact us with a short description of your project and we will tell you how we can help.

Frequently Asked Questions

What does a Windows driver consultant do?

A Windows driver consultant designs, writes, debugs, and reviews kernel-mode and user-mode driver software on your behalf. Engagements range from writing a production driver from scratch, to fixing Blue Screens in an existing driver, to reviewing an architecture or codebase before you ship. We work as an extension of your engineering team for the length of the project.

How do I hire Joya Systems for a Windows driver project?
