Edmonton, Alberta, Canada
Summary
🤩
Rockstar🎓
Top SchoolBradley Wood is a compiler developer and Ph.D. candidate with a decade of experience specializing in JVM JIT compilers and low-level performance engineering. At IBM he contributes to the open-source Eclipse OpenJ9 project, implementing AVX-512 support, SIMD intrinsics, and hard-to-reproduce optimizer fixes that improved runtime performance and correctness. His work spans compiler internals, target-specific optimizations, and practical intrinsics like StringLatin1.inflate, reflecting deep familiarity with both architecture and code generation. He combines this production experience with academic research in programming languages, compilers, distributed systems, and software quality, and has taught core courses from operating systems to embedded systems. Based in Edmonton, Bradley is comfortable moving between collaborative open-source development and rigorous research, often turning theoretical ideas into tangible JIT improvements. Colleagues describe him as a meticulous debugger and quick learner who seeks elegant solutions to intermittent, high-impact bugs.
