CASE STUDY INDEX — 04
Products and platforms where I owned meaningful parts of design, implementation, delivery, or infrastructure.
Full Stack / Web & iOS
A private financial command center for holdings, research, targets, and spending — available on the web and as a native iPhone app.
I own and maintain the full stack in production: SwiftUI, Vapor, PostgreSQL, and Redis on Hetzner, secured with MFA, passkeys, and Face ID.
Private repository — walkthrough available on request
iOS App / AI Memory
A private second brain for people who want to own their memory: organized Spaces plus Hermes, an AI agent that reasons only over what you've saved.
Live on TestFlight — capture becomes structured, searchable memory, and every AI answer is grounded in your own vault, self-hostable end to end.

Backend API
The self-hosted engine behind HermesVault: a Swift 6 / Hummingbird 2 API whose kb-compile pipeline turns raw Markdown into a queryable knowledge base with pgvector semantic search.
Runs in production as private infrastructure — per-tenant vaults, JWT auth, Docker deploys on a bare VPS.

Backend / Client Work
Client delivery for a real-time community platform: I built the Go backend — auth, membership, and live group chat over WebSockets — plus client-side product work.
Shipped with an OpenAPI spec so client teams integrated quickly; JWT-secured sessions and PostgreSQL persistence delivered on schedule.
