Senior🎓
Top SchoolArata Miyazaki is a Vice President with 16 years of experience blending investment execution, operational value creation, and technical fluency across private equity, M&A, and fund management. He has led structuring, valuation, due diligence and post-investment operating work—most notably managing development projects like Japan’s largest Ferris wheel and exiting multiple investments. Prior roles span distressed-asset disposition, bank bad-debt bulk sales advisory, derivatives product marketing, and early-stage web/system project management, bringing a rare mix of finance, operations and hands-on technology leadership. A Tokyo University of Science mathematics graduate, he pairs analytical rigor with practical program delivery, often owning both strategy and execution for turnaround and growth mandates. Unusually for a senior finance executive, he is an active open-source contributor and Haskell enthusiast who has fixed floating-point and ABI issues in GHC and contributed cross-platform GUI fixes to wxWidgets, reflecting deep low-level technical expertise. Based in Chiyoda, Japan, he combines fund formation and advisory skills with engineering-minded problem solving to drive complex, operationally grounded investment outcomes.

Back-end DeveloperContributions:19 commits in 1 year 10 months
Contributions summary:Arata contributed significantly to the Glasgow Haskell Compiler (GHC) by adding tests and fixing bugs related to floating-point arithmetic and SIMD vector operations. They implemented tests for calling conventions of foreign import primitives, integer-to-float/double conversion, and IEEE 754 compliance. Additionally, the user supported auto-detection of register limits and improved documentation and code generation for AArch64 and x86 architectures. Their work primarily focused on improving the compiler's accuracy and performance.
