A Walking City

Portfolio

Selected work, from AI assistants shipped on millions of devices to calendar infrastructure for AI agents.

CalendarBridge

calendarbridge.com ↗

Cross-platform calendar sync and AI scheduling: Google/Microsoft/Apple calendar synchronization, AI Email Assistant, and an MCP server that opens calendars to AI agents. One issued US patent.

Attack Surface Scan

attacksurfacescan.com ↗

Hosted external attack-surface monitoring. Passive checks (headers, TLS, DNS, certificate transparency, open ports) run only against domains a tenant has proven it owns by DNS record, and every scan is diffed against the last, so it's a change feed rather than a one-time report. Nothing to install and no code to change: you get a posture score, a branded PDF you can hand to a client or an auditor, and a hosted MCP server that opens the account to AI agents.

vbgnt

vbgnt.com ↗

Describe a game in one sentence and play it in minutes. Every game is built in a disposable game-dev workstation that materializes on demand: a cloud microVM with a full Godot install, the coding agent, generative 2D and 3D asset pipelines, and a headless browser the agent uses to playtest its own work before it ships. What comes out is a web build that runs on a phone, a TV, or a desktop, with touch controls and gamepad support, published to an arcade of your own. Started as my personal dream game console; now a product.

Counsileum

counsileum.com ↗

An AI consultancy run as a bench of specialists: research analyst, forward-deployed engineer, engineering planner, UI designer, GTM strategist, deck producer, coding engineer. Brief one, answer a short intake interview, and it goes to work in a persistent cloud workspace. What comes back is the artifact itself: a research report as HTML and PDF, a branded 16:9 deck, a scoping document, or an opened GitHub pull request.

The Modern Kit

themodernkit.com ↗

An everyday-carry and gadget blog written and published by agents. Agents write to the blog via a WordPress compatible MCP server interface.

Mochi Zen

mochi-zen.com ↗

An RTT hypnotherapy app for weight loss, anxiety, and sleep: guided audio sessions, a journal, and weight tracking, built on the Rapid Transformational Therapy method. React Native and Expo on the front, Firebase for auth and data, an AI meal scanner that turns a photo of a plate into per-item macros through a Gemini vision model, and a subscription service that reconciles Stripe web checkout with Apple and Google in-app purchases into a single cross-platform entitlement. Shipped on the App Store and Google Play.

Postero

A social scheduler built for agents as much as for people. One post fans out to LinkedIn, TikTok, Instagram, Threads, Facebook, Pinterest, YouTube, WordPress, Slack and Discord, every account on its own schedule, with per-platform text variants and timed replies that can come from a different account. Behind it sits a short-form pipeline that turns long video into clips: Transcribe and Rekognition find the highlights, hook text is burned over the opening seconds, and licensed music is mixed in. The entire surface is also an MCP server, so an agent can plan and schedule a month of posts through the same model code the UI uses.

Palace of Fine Arts Theatre

palaceoffinearts.org ↗

The San Francisco venue's official site. I ported it to Webflow, then ported it back off again: it now runs as 100% static HTML.

AWS

Redforge

Red teaming for AI features, run from the outside. Point it at an AI endpoint (no codebase access) and it fires 24 adversarial attacks across prompt injection, system-prompt extraction, jailbreaks, data exfiltration, and business-logic abuse. Claude mutates each attack to fit the target's actual use case before firing it, then grades the response for severity with an explanation and remediation advice. Attacks run async off a queue so you watch findings land live, export the report as Markdown, and re-run a single attack once you've patched it.

LLM Security

CladClaw

A one-click host for secure, personal AI agents. Each subscriber gets their own OpenClaw instance on Fargate Spot: a Graviton container running the agent alongside a real Linux desktop, provisioned by Terraform. The dashboard is the part I enjoyed most: a Windows 95 desktop in the browser, where the agent's actual X session is a noVNC window you can watch it work in, and you talk to it in a window that behaves like AIM.

Viv / Bixby 2.0

The AI assistant from the creators of Siri. As Android Lead I re-architected the client and its multiplexed client–server protocol; after Samsung's acquisition it shipped as Bixby 2.0 on millions of Galaxy devices.

Circa News for Android

en.wikipedia.org ↗

The mobile-first news app that broke stories into atomic facts. I built the Android version, featured in Google Play's Best Apps of 2013, plus Google Glass, Sony SmartWatch, and Apple Watch editions. WIRED's Jan 2015 cover story caught me breaking the first U.S. Ebola case to the newsroom.
