Summary
🤩
Rockstar🎓
Top SchoolMichael Maitland is a software engineer with a decade of experience specializing in compilers and computer architecture, currently advancing low-level systems at Meta. He has deep LLVM expertise, notably contributing to the RISC-V backend—implementing and optimizing vector instructions, widening/narrowing FP conversions, and improving codegen for vector operations in one of the most influential open-source compiler projects. Prior roles include senior compiler engineer at SiFive and a mix of startup and cloud experience as a CTO/co-founder and SDE at Amazon, giving him both production rigor and product-building instincts. Based in New York and trained at Cornell, he blends systems-level rigor with practical delivery, often focusing on garbage collection, vectorization, and machine-specific code generation. An uncommon strength is translating architecture-level ideas into concrete compiler transformations that enable new ISA features to be used efficiently by real-world code.
