High-performance developer, CUDA ninja
Could've been better
Levi has deep expertise in Cuda engineering. I would highly recommend Levi for Cuda related questions. We met for 30+ minutes. I took 3 pages of Notes. Levi explained to me about: * thread warps vs thread blocks * when __syncThreads are used * volatile tag + memory barriers * memory coalescing (why threads read memory in "gridSize increments") * cuda profiling issues (nvvp, visual profiler), occupancy * dynamic parallelism + existing tools (cub + thrust) Basically, if you find yourself reading sections of the "Cuda C Programming" 3+ times and still not understanding it, just hire Levi -- he'll clarify all your questions. Lastly, Levi's humbly also very clear about issues he doesn't consider himself an expert in. I threw 2-weeks worth of stored up Cuda questions at Levi. Levi answered 98% of them in authortative detail, and was upfront in stating that the other 2% was out of his domain of expertise.

Levi has a wide range of knowledge. We were able to break down my problems into easily digestible chunks and solve from there.

Levi is THE ONE when it comes to CUDA. Could not wish for a better mentor on the subject.
