PORTO, PT / SOLO PRACTICE / AVAILABLE Q4
I design, build, ship, and operate product systems: SwiftUI on the phone, Go and Vapor on the server, Kubernetes underneath. This site included. The numbers below are its own.
YOU NEED A CONTRACTOR
Ship the product with one senior engineer instead of a team you have to assemble first. Design through deployment, one person accountable for all of it.
YOU'RE HIRING
Ten years, four countries, and case studies where I owned the whole system, not a slice of it.
WRITING
Notes on architecture, iOS, and solo product work, written while the decisions were still open.
THE ARCHIVE
An Obsidian vault of research fragments and links, indexed here as it syncs.
Hosted products and systems I shipped and still stand behind.
Web & iOS products
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.
iOS products
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.
Backend systems
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.
