Compiler and AI systems engineer building the infrastructure underneath modern products, then applying the same operating system to marathons, triathlons, and BJJ.

Real systems, production pressure, and disciplined iteration. The page works best when the photo stays dominant and the supporting details read like field notes, not a dashboard.
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.

Privacy-first macOS app for AI contract review. Flags risky clauses with severity scoring; every finding verified against source text.
Project Dossier
One flagship owns the section. The rest of the work reads as a tighter evidence log instead of a second set of co-headliners.
DevTools · Hacker News Featured
Homebrew-installable multi-agent PR review CLI. Parallel AI agents hunt concurrency, security, and logic defects; a judge agent cross-verifies.

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
The photo should carry the chapter.
Training logs still matter, but they work better here as supporting evidence after the finish-line image lands instead of competing with it from a side panel.
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.
