Systems · evidence · boundaries
Building what excites me.
I design and build AI products where trust, retrieval, privacy, and durable state need to survive contact with real systems.
The work starts before the model: context, evidence, and the edge of the system. 01 / Selected work
Small surfaces. Serious boundaries.
Projects are ordered by how clearly their documentation supports a public case study—not by invented impact.
mastra-pii
PII redaction for Mastra agents as an adapter, not a detector: one interface over a Presidio deployment — the package owns integration, the deployment owns intelligence — with a deterministic Indian-recognizer layer and fail-closed defaults.DocNeedle
Local-first SQLite FTS5 tool for indexing docs, retrieving chunks, and checking stale terminology.Reliable AI starts where the happy path ends.
02 / Current focus
Patterns that make agent systems easier to trust, inspect, and improve.
The work stays centered on product and engineering moves that help people understand the boundary, the fallback, and the evidence path.
- Memory and context boundaries
- Evaluation tied to user value
- Privacy-aware agent workflows
- Fallbacks that preserve useful outcomes
03 / Writing
The note behind the decision.
Each note starts in a public README or accepted ADR and returns to the project that made the question concrete.
Drop-in PII redaction for Mastra agents
Agent loops touch sensitive text at every boundary — prompts, tool calls, traces, memory. The hard part is not detection; it is integration.
Citation-first RAG needs an insufficient-context path
A citation-first demo earns trust by showing its sources, naming its infrastructure, and treating insufficient context as a valid result.
Separate the product surface from the benchmark harness
DocNeedle's README is persuasive because it treats normal CLI use and repo-specific evaluation as different things instead of collapsing them into one story.
Trusted ingress before more tools
Career Copilot shows why a single-owner agent benefits from tight trust boundaries before it grows new capabilities.
