Resume

Having started my education primarily with mathematics, I was blissfully ignorant to all the underlying engineering required to get my abstracted Haskell or Julia code to compile. However, as the performance requirements became stringent for the scientific problems I worked on, it required me to get a better handle about what was actually being generated. I was not content to simply regard the compilation process as black magic and it led me into the work of compiler engineers.

I am currently still on my journey working down the stack, and working as a compiler engineer has been the perfect medium to do so.

Experience

Last updated July 28, 2025.

Compiler Engineer, Microsoft

Sep 2024 – Today

Modernizing the DirectX Shader Compiler into upstream LLVM.

• Designed the implementation of root signatures in the Clang frontend: 0, 1
• Implemented parsing, semantic analysis and validations of root signatures: 2
• Pushed for better root signature error reporting for dramatically better user experience: 3, 4
• Implementation of various HLSL intrinsic functions for both the DirectX and SPIR-V backends: 5, 6, 7, …
• Other various bug-fixes, clean-ups and expected improvements to llvm

I also take pride in my quality and quantity of code review.

Open Source Contributions, MLIR & HEIR

Sep 2023 – Aug 2024

Taking time to getting started with contributing to open-source compilers/frameworks.

HEIR

Worked on lowering number-theoretic transforms to the arith dialect. Leading to involvement in the mod_arith dialect design and implementions considerations.

• Implemented lowerings of the poly dialect to the “standard” dialects: 0, 1, 2, …
• Introduce the mod_arith dialect: 3, 4, 5, …

MLIR:

Worked on the SPIRV dialect.

• Add lowering of index to SPIRV dialect: 6
• Add constant folding for many SPIRV ops: 7, 8, 9, …

Odin:

• Minor bug fixes: 10, 11, …

Functional Programmer, Cisco

Aug 2022 – Aug 2023

• Implemented new features for the ConfD/NSO transaction engine
• Worked on the internal YANG compiler and the C/Python API
• General maintenance of mentioned components, working with Erlang, C, Python and LuX
• Practical work experience with git, JIRA and jenkins on a large codebase
