01 · Problem

AI hallucinations in legal briefs

The client needed to keep a human as the final decision-maker (a lawyer certifies every filing under Rule 11 and state bar rules, so citations can’t be automated away) while still speeding the review. I built a stoplight process that lets a paralegal or attorney focus on the passages that carry the most risk instead of re-reading everything. I delivered the proof-of-concept; the client’s development team is building the production version.

Citation validator summary: 51 citations triaged by risk with deep-investigation tiers

The validator’s summary view. 51 citations scored low / moderate / high risk, with the riskiest escalated to a deeper multi-model review tier.

Architecture
  • Human as final decision-maker
  • Multi-LLM architecture
  • Panel design to drive an accuracy number
  • AI escalation: uses low-cost models to assess and spends expensive model calls only where necessary
  • AI triage of technical and regulatory content

The time and effectiveness of a marketing team

An in-house B2B marketing team was carrying twelve people across LinkedIn, email, blog, SEO, and sales outreach. I built a coordinated AI system that sized each task to the smallest model that could do it (Haiku for high-frequency work, Sonnet for the judgment calls), behind a deterministic harness that handled sequencing and formatting so the models only did what actually needed a model. Custom MCP connectors wired it into the real stack (Apollo, HubSpot, a custom Outlook connector), with sales staff reviewing every outbound message. The team went from twelve to 2.5 FTE at roughly $33 a month in model spend.

A structured dataset of executive interviews for media analysis

This started as a body of interviews to train on and a proposed AI interviewing tool, and evolved into an executive-interview media-analysis platform. A low-cost batch pipeline turns raw interviews into a vector-searchable dataset at high volume, delivered through a chat interface anyone can query in plain language.

Scale: 237.3M words analyzed, 26,368 hours of podcast, 40,867 long-form interviews, 519 added in June
Ingest: discover, download, and transcribe interviews and podcasts from dozens of sources (Apple SpeechAnalyzer on-device, YouTube). 44,000+ transcribed.

Process: a batched, multi-pass classification pipeline that runs a 3-level role × industry × scale taxonomy, then thematic and buyer-journey scoring across 41,000+ transcripts.

Analysis: the queryable payoff. Industry, role, and company-scale breakdowns feeding media analysis and an ICP profile builder.

Creating a shared context for a person and their agents

Kyle is a shared notebook between a person and their AI: with either able to create notes that appear instantly for the other. The app is a native iPhone, iPad and Mac app and is exposed to on-device Siri and Apple Intelligence and to other connected agents. It creates a shared context the AI agent or person can access at any time and any place.

Kyle on iPhone: agent-written notes, live on device.

mdEdit is the local-only version of the same idea: a native macOS markdown editor where Claude reads and edits your open documents live over MCP, entirely on your Mac — no cloud, no copy-paste. Free and open source.

Approach
  • Client mobile applications (iPhone / iPad / Mac)
  • MCP
  • Dashboards and reporting
Next Steps

I am happy to go over any of these projects in detail. If you have any questions, let me know.

This page was written with Claude in mdEdit — a native Mac editor I built so Claude and I can edit documents live, on my Mac. Free.
