Production systems I designed and built for clients. Most of this code is private, so each page explains the problem, the design and the outcome. I'm happy to go deeper on a call.
Invoices read by an AI model against a strict schema, routed for one-click approval in Slack, and synced into the ERP with an append-only audit log. 95%+ first-pass accuracy, in daily use.
A two-tier agent on the Anthropic API: a fast model routes, a larger model reasons only when needed, answers are grounded in real help content, and clear rules hand off to a person.
A central internal operations app connecting the store, help desk and fulfilment provider. Cancellations and refunds run from one screen with permission checks and a BigQuery audit log.
Automated refund flows for whole-invoice, partial and line-item refunds on the Recurly API. Every refund is validated against the live invoice before any money moves.
A scheduled n8n workflow that finds and enriches leads, scores and tags each one with an AI step, drops them into the CRM and notifies the team. Hands-off, every day.
RLHF benchmark tasks with reference solutions and automated graders, including multi-step agentic tasks, plus the harness that scores runs.
A dashboard that turns workforce data for 500+ employees into performance patterns and retention signals using LLM-driven analysis.
