Christopher F Clark Email and Phone Number

The Yacc++ author and itinerant compiler specialist. Numerous successful projects from architecture and design through code and benchmarking--including evangelizing the work to key clients, bringing in evaluation opportunities that have led to design wins. In the process, I've mentored many engineers who've become successful in their own right.After retiring I accepted a contract to work remotely for NuoDB developing an expression evaluator for their new SQL engine. Due to the vectorization, it is over an order of magnitude faster than the evaluator it is replacing. It was architected to allow simple replacement by an LLVM code generator once the entire product is stable. I then wrote a PowerShell interpreter (that helped scan for insecure code) for FileScanIO. And, after that built the IR for an SQL engine for DataPelago with a backend in Rust and frontend in Java using GraphQL to communicate between the two implementations.Last job before retiring was working on a variety of projects at Google in support of Mobile Device Latency Testing--the largest of which was the design for a queueing system to support allocating test machines with support for quotas and priorities.Architected "Cave Creek" regular expression hardware accelerator at Intel and co-developed the software solution that replaced it which successfully accelerates Snort to 3x its normal speed, resulting in design wins in the networking and security markets, such as Cisco.Some other highlights: the "vmod" Verilog compiler for Intel, the Alpha optimizer for the Unix Group at DEC, the architecture of an optimizing ANSI C compiler for Honeywell, and the "Common Backend" for the compilers at Pr1me.Former Editor of Parsing Patterns column in SIGPLAN Notices, who often posted on comp.compilers (as cfc@world.std.com) and tweeted about security as @intel_chris on twitter.Specialties: Compilers, Parsing, Lexing, Regular Expressions, Automata, Instruction Sets, Register Allocation, Optimization, Code Generation
