Quentin Barnes Email & Phone Number

I’m considered a versatile and resourceful software engineer with an extensive background working with high performance teams and leading technical projects from concept to completion. I possess deep technical expertise coupled with the ability to collaborate and communicate effectively with individuals at all levels throughout the organization. I have a strong track record of creating innovative software solutions and tenaciously debugging code that's impacting revenue.I’m recognized for: • Successfully defending the Linux kernel’s routing cache algorithm in patent litigation. • Uncovering and fixing a defect costing company $100K/hour in lost revenue. • Reducing Yahoo!’s data centers’ load balancer costs by $20MM/year. • Designing a radical new approach for Linux's Kernel Probes on ARM, which solved all existing multi-processor and real-time problems found in all other implementations. • Designing a virtual critical section method that substantially reduced locking overhead and allowed reuse of slower, cheaper hardware for new deliveries saving the company $100MM on an existing contract. Extensive experience in: Linux/BSD/UNIX kernels | Software Development Life Cycle (SDLC) | C and C++ | ARM & x86 assembly | Simulation and logic analyzers | Performance analysis | ISO C & C++, ELF, ABI, and POSIX standards | Open Source Software development and GPL | Compilers and toolchains | Git, GitHub, and Subversion | Jenkins | gdb / crash / perf | Mentoring / Leadership I welcome making new connections. Please reach out if you’d like to discuss Free and Open Source Software or my personal interest in retrocomputing.
