I build production systems fast — because I architect the AI and agentic workflows that help build them. The build times below are real, hands-on hours.

Telephony AI~3 days

AI call screener

The voice front-end to my assistant, Margo: a tiered screener that answers the phone and texts, works out who's calling and why, and passes along only what actually needs me. Real-time telephony wired to an LLM persona, running at the edge.

Marketing site~15 hrs · 2 days

A venture site, brand-checked at build time

The marketing site for my venture, KMO Solutions Foundry — React and Vite prerendered to static HTML on Cloudflare Workers. It ships with a build-time brand-voice linter that fails the build on off-brand copy, so the site can never drift from its own voice guide.

Four demo sites in under four hours

Four production-quality demo sites across different verticals — a restaurant, a law firm, a retail shop, and a salon — built from one shared component monorepo to show the CRM in context. Roughly an hour each, because the hard part was built once and reused.

ceryce.com — this very site

The site you're reading. Hand-built in Astro with a neon-cyberpunk brand and prerendered to Cloudflare Workers — now growing a server-rendered /admin dashboard, gated by Cloudflare Access, to drive Margo. Public and open source.

Agentic tooling7 skills

A reusable Claude Code skill suite

The tooling that makes multi-agent engineering repeatable: context-loaders that prime a session with the right docs in the right order, a crash-recovery skill that rebuilds progress from git history and a ledger to resume a dead run, an in-flight decision framework, CI bootstrappers, and doc-sync. The tools that build the things that build.
