Shipped systems, searchable by the parts behind them.

These writeups are meant to survive two reads: a fast skim from a hiring manager and a more skeptical pass from an engineer. They keep the product path, architecture, tradeoffs, and failure modes close together.

StageFlow
Open-source frontend quality platform: eight scanners, one report contract, and per-project regression memory for CI.

StageFlow is an open-source, self-hostable frontend quality platform. It runs eight scanners — accessibility, performance, SEO, links, security headers, social metadata, content quality, and agent-driven navigation — as one pipeline behind a single report contract, and remembers a baseline per project so every scan can answer the question that matters in CI: did this change make the frontend worse?

AlchemizeCV is an AI-powered resume-tailoring and job-application platform.

Access Control Platform
Cloud-managed physical access control with offline-first site orchestrators and hardware reconciliation.

A commissioned access-control platform that manages card credentials, doors, and access levels across remote sites from a centralized cloud control plane. An on-premise Go orchestrator owns each site's state in SQLite and keeps the physical controllers enforcing access even when the cloud link is down; the cloud holds only a projected read model.
