HOW I SHIP
What I bring.
Scale: multi-region, multi-cloud CDNs at Warner Bros. Discovery — AWS, Fastly, GCP, Akamai — serving hundreds of millions toward a 99.99999% availability target.
Speed: creator discovery at Influencer — AI inference with creator, audience and demographic filters, vector search over embeddings, third-party API latency down from 30s to 900ms.
Rigor: test infrastructure that holds — Testcontainers against live PostgreSQL, SQS and Redis, 100+ test cases, an SDK replacing 10,000+ duplicated lines across six microservices.
Agents: native ZCode chat and a Hermes Agent harness for agent-orchestrator, both in review upstream — shipped the same way I've always shipped: reviewed, tested, merged.

FAQ
Fair questions.
Do agents write all your code?
No. Agents are tooling, not a substitute for judgment. Every change still goes through the review and tests I've used since shipping to hundreds of millions of users — a diff merges only when it's right.
What is agent orchestration, concretely?
Running many agent sessions as one system: spawn, supervise, steer, review, recover. I build the harness itself — my ZCode chat integration and Hermes Agent harness are in review on agent-orchestrator.
Can I see the work?
Yes — it's the resume, in public form: 54 merged PRs across 16 repositories, including rustfmt, screenpipe, cal.diy and Qdrant. Full table on my GitHub profile.
What size of team and product is this for?
The scale I know: products with real users and real consequences — streaming, fintech, creator platforms — that want AI-native speed without giving up review rigor.
How do you prefer to be reached?
Email, one click from every page. Issues and PRs on my repos reach me too.
Was this site built by agents?
Partly — but the claims on it are all resume: WBD, Influencer, Luxury Presence, and public PRs you can open. No build step, static by design, works from file://.
