Retrieval that admits when it doesn't know
Grounding, citation, and a refusal path. An answer with no source is a bug, not a feature.

01Indexfield · drift — three lines
I build systems that think and interfaces that don't get in the way.
Full-stack from the metal up — data plane, model, and the pixels in front of it.
Most of my work is deciding what not to ship.

03Modelsfield · graph — how I build with them
Evals before prompts
A scored set beats an opinion. Every prompt change ships against a suite that can veto it.
Agents on a short leash
Narrow tools, explicit state, hard budgets. Autonomy is earned per-capability, not granted wholesale.
Latency is a product decision
Streaming, caching, and model tiering are UX, not infrastructure trivia.

01
Ignite IQ
visit ↗Agentic workflow platform. Built the orchestration layer, the eval harness that gates every release, and the interface that makes a non-deterministic system feel accountable.
02
Retrieval Pipeline
Hybrid retrieval over a few million documents. Reranking, citation spans, and a cache that cut median latency to a third without touching recall.
03
Realtime Surface
A collaborative editor with optimistic state and conflict resolution that never blocks a keystroke. Sixty frames a second on a five-year-old laptop.
04
This Site
visit ↗260,000 particles simulated on the GPU every frame, morphing between five attractor states. WebGPU compute via vgpu, with a 2D fallback that degrades quietly.
