Production migration · principal's engineering work at Mediavine

A 100k+ req/s auction server, moved from Node.js to Rust without stopping.

S2S is the real-time bidding service behind Mediavine's ad auctions — every page view gives it milliseconds to run an auction before the opportunity is gone. Giancarlo led its migration from Node.js to Rust as an incremental replacement, not a rewrite: production traffic ramped from 2% to 100% in measured stages, and every stage had to earn the next one with production data.

The correctness gate was deterministic: generate production artifacts, ingest them in development, and make the bytes match. If the bytes didn't match, it didn't ship. Feature work, reviews, and production support never paused during the 43 days the migration took to reach full traffic.

The latency and efficiency gains compounded into direct business impact: roughly $87.5k in additional publisher revenue in the first 24 days after launch, on top of thousands of dollars in daily infrastructure savings.

Shipped product · NG Tech

Let's Dance Robot: a native iOS app through App Store review.

A native iOS app, live on the App Store, shipped end to end by a very small team. It doubles as the proving ground for iOS Builder — NG Tech's agentic shipping pipeline that pairs token-efficient AI feedback loops with automated App Store Review submission handling, while release decisions, reviewer replies, and privacy disclosures stay human-approved.

• Versioned privacy surfaces — every shipped app version pins its own privacy policy URL on this site, so the disclosures each build was reviewed against stay live forever.
• Remote operational controls — the app's ad stack reads a remote kill switch served from this Worker, keeping production levers in one place.
• Repeatable release loop — build triage, simulator verification, screenshots, and review artifacts handled by the same pipeline every release.

Live platform · NG Tech

The publishing platform serving this page.

The NG Tech Insights hub is an agent-driven research and publishing pipeline: signal collection and synthesis run through supervised agent workflows into Notion, an editorial gate approves what publishes, and a deterministic publisher turns approved entries into committed Markdown and a typed content manifest baked into a Cloudflare Worker at deploy time. Zero frontend frameworks, zero runtime data fetching, near-zero infrastructure cost.

• Server-rendered TypeScript — every page is a typed template string with inline styles; no client-side JavaScript is shipped at all.
• OAuth-protected MCP ingestion — hosted agents write signals through a separate Worker exposing Model Context Protocol tools, with server-side dedup.
• Deterministic publishing — reruns without upstream changes produce no diffs, so the whole pipeline is safely re-runnable from CI on a schedule.
