Bow Shock Systems solves hard problems in software

I solve business critical problems in operating systems, networking, and file systems — quickly. For urgent showstopper bugs, I have a track record of finding a solution or a workaround in two weeks or less. See my contact information to schedule a free consultation.

About

I’m Valerie Aurora, a systems software consultant with 25 years of experience in operating systems (Linux/UNIX/Darwin), file systems, networking, and systems software. I have written code for multiple file systems, the Linux kernel, TCP/IP internals, VPN services, bootloaders, device drivers, interrupt controllers, and silly games. My primary language is C but I also write Go, Python, shell, and a little of everything else.

Free consultation

I offer a free initial consultation of up to three hours. See our contact information to send information by email and/or schedule a meeting.

Experience

I have designed and implemented solutions to dozens of critical software issues in the areas of file systems, networking, operating systems, and systems software in general. A few examples:

• Fixing the calibration code for a giant laser that shoots at satellites
• Debugging silent data corruption in hardware, software, and firmware
• Saving billions of disk writes with ten lines of code
• Designing, implementing, and debugging file systems (ZFS, ext4, ngnfs, fs freeze)
• Inventing and implementing a low latency path MTU discovery algorithm
• Fixing a complex system-wide service performance issue in a commercial VPN service
• Fixing bugs in the Linux TCP/IP stack
• Performance tuning production web applications
