UI that holds up under heavy data — design-system-driven React, Svelte 5, and custom d3 + THREE.js when SVG runs out of room.

Performance is design work.
The pages I build run faster than the ones I replace. Query plans rewritten where the index actually helps. Render paths trimmed to the ten thousand DOM nodes that matter. Build tooling chosen for the right reasons, not the loud ones. The numbers come from the work itself.- 200ms first paint where the prior build took 2 seconds
- 4–10× faster builds across a real-world TS monorepo — Node 12 → 20, webpack → Vite / TurboRepo, zero downtime
- 10K-polygon scenes at a steady 60fps via off-screen color picking

Three disciplines, one practice.
The work I do best lives where UI, services, and infrastructure meet — and that's where the cards below pick up.
Backend & data infra
Multi-tenant services that stay observable as they grow — Postgres, Kafka/Avro event streams, Redis state, and SSE/websockets to the browser.

Platform & AI
Infrastructure that makes everything else fast: monorepos, Vite, observability, CI — and the agent / MCP work I’m pushing into now.

A second project is in design — landing here once it is out of the sketchbook.

A third project is queued behind the second — same story, different shape.

What I’m writing about right now.
In-depth writing on software engineering and the subjects I follow closely outside of it — practical, opinionated, and grounded in real work.
