~/ Senior Software Engineer based in Singapore, building distributed systems, developer tooling, and the occasional WebGL side-quest. Currently shaping the platform team at Northwind Labs. I care about observability, type safety, and code that survives the third refactor.
A 12ms cold-start build tool that incrementally compiles monorepos with content-addressed caching. Replaced Webpack for three internal teams and cut CI time by 64%.
A conflict-free replicated ledger for multi-region financial workloads. Uses Raft consensus and CRDT merges to guarantee exactly-once settlement across 3 continents.
A self-hosted observability stack — traces, metrics, and logs in a single 8MB binary. Powers incident response for 14 production services at Northwind Labs.
A TypeScript LSP plugin that flags unsafe `any` escapes in real time. Adopted by 6 internal codebases; caught 1,400+ type regressions before they shipped.
Closed a 6-month-old race condition where inotify events could fire before the watcher's internal state was committed. Added a regression test.
Dev-dependencies were silently ignored when inheriting from `[workspace.dependencies]`. Patched resolver and updated docs.
Tag-based invalidation was missing revalidate-time fallback. Added a unit test covering 4 edge cases and shipped the fix.
Open to senior/staff engineering roles, contract architecture work, and advisory engagements on developer tooling and distributed systems. I respond within 48 hours, weekends excluded.
