A protocol-first information hub for navigating news, publications, people, and conversations across the open social web. I designed and built the product experience, web and SwiftUI clients, gateway and XRPC APIs, ingestion pipeline, data model, deployment architecture, and operations using ATProto, Jetstream, Next.js, SwiftUI, PostgreSQL, OpenAPI, and a Thin AppView architecture. The platform preserves source context and user-owned subscriptions and preferences while helping people move across the web.

Portable, ATProto-native read-later infrastructure designed to let bookmarks and saved content move with the user rather than remain trapped inside a single application. The system combines a Next.js application, Swift/Hummingbird services, public ATProto lexicons, OAuth and DPoP authentication, PDS write-through, browser integration, and reusable Swift and TypeScript tooling. LatrKit provides shared infrastructure for adding compatible saving and retrieval features to other applications.

A small-business-minded social media management platform built around portable identities and user-owned publishing data. Skej coordinates content, scheduling, publishing, and social presence across services without making a proprietary scheduler the permanent owner of a business’s data. Its architecture includes Next.js, Swift 6 and Hummingbird workers, hosted OAuth, durable scheduling state, CI/CD, and ATProto-native records.

Shared infrastructure for making reusable skills and contextual knowledge available across AI agents, models, and development harnesses. I built and operate the system through Railway so agent capabilities and context can be developed once and reused across different tools and workflows. The project treats context engineering as durable infrastructure rather than reducing every agent session to an isolated prompt.

An integrated, open-web productivity environment spanning mail, calendar, notes, tasks, documents, and a personalized home experience. Atelier is designed as a user-controlled home on the web: a layer that understands relationships between applications and surfaces the right information or action without replacing the underlying services. The suite is organized as an eight-app monorepo with shared infrastructure supporting portable data, collaboration, and AI-assisted workflows.
