I — The Origin
Damascus to San Jose.
Loading the pinned map narrative without dropping to an empty black frame.
II — The Work
Swift–C++ interop at Apple. Compiler performance at SiFive. Production LLM systems, inference optimization, and open-source accelerator bring-ups after that.

Shipped Swift–C++ interoperability across the Swift/Clang toolchain — AST bridging, ABI integration, name mangling — adopted by 1,000+ internal projects.
Project Dossier
Each entry is a shipped system with a constraint, a measurable outcome, and enough surface area for real engineering judgment.
SiFive · 2022 – 2023
Tuned Clang/LLVM vectorization cost models and RVV codegen heuristics for RISC-V. Built the microbenchmark suite that prevents regressions.

III — The Athlete
Marathons, Olympic-distance triathlons, BJJ podiums. The discipline is identical — train the system, log the telemetry, ship the result.

Seattle Marathon · 26.2 · Finish
Every mile, logged. Every finish, earned.
Training becomes measurable when every route, split, and effort gets turned into a field log.
Field Note
Finish lines are measurement, not mood.
The training log matters because it keeps the result honest: pace, distance, misses, repeat attempts, and the quiet accumulation underneath a public finish.
Race Telemetry
The route data stays in the chapter as supporting evidence: a quieter read on pace, terrain, and repetition after the finish-line image lands first.

IV — The Proof
After telemetry comes the human record: race mornings, summit light, podiums, and finish-line proof.
Field archive
Observed, not art-directed.
Weather, fatigue, bad lighting, and the parts that feel too human to brand are what make the chapter credible.

Compiler work, AI infrastructure, product systems, public-sector modernization, or anything where correctness, performance, and judgment matter more than surface polish.
