I work at VASS. Since late 2022 I have been on the Inditex account, on the app that store staff across the group use every day, and since 2025 I lead its iOS team. Before that I moved through banking and retail for other clients of ours: Santander, Mercadona, Unicaja, Banco Pichincha. All of those are client projects — VASS is the employer.
Then there is my own work, which I sign as OgamLabs. Two apps on the App Store, and I keep their API, their database and their server running myself.
Based in Madrid. Happy to talk about senior iOS work, leading a team, architecture, or developer tooling.

Fuel prices across Spain and France, from the official open data. The app is Swift and SwiftUI; the API is TypeScript on Fastify over PostgreSQL, and I operate it. The public engineering case study covers the Swift 6 offline-first client, the official-data ingestion and the production operations — without exposing the product source.
Product site · App Store · Engineering case study
A published SwiftUI word game: five words hiding one common thread, one short round a day. 4,015 original puzzles, 11 store locales, 1,128 passing tests. The long part was not the game but the pipeline that generates, validates and reviews the catalogue and the store assets.
Product site · App Store · Engineering case study
A real Xcode application that builds, not a diagram: a single app target inspired by Clean Architecture, with MVVM, typed Router navigation and manual factory-based dependency injection. 194 Swift Testing cases across 27 suites hold the boundaries in place, with zero third-party package dependencies.
Code and decisions · CI checks
A Go CLI that sets up iOS projects with Clean Architecture, MVVM, Router navigation and optional AI coding packs. Its transactional generator validates every destination before it writes and never overwrites a file. 421 automated tests; its 34 provenance-tracked skills include 25 self-contained Swift 6 examples.
Two tools I built because I needed them. Each has a public case study; the tools themselves are not released yet.
PRDPlanner and HarnessHub
A PRD → plan → build workflow with bounded context, dependency-aware phases, parallel verification and a stage whose job is to refute what the other stages found, before a human decides. A public edition is in preparation.
A local-first composer for skills, subagents, plugins and MCPs that produces reproducible multi-harness bundles without installing or executing anything it packages. It is currently in local beta.
- Apple platforms — Swift 6, SwiftUI, UIKit, Observation, SwiftData, StoreKit 2, WidgetKit, App Intents
- Architecture — Clean Architecture, MVVM, Router/Coordinator, modular SPM packages, dependency injection
- Quality — Swift Testing, XCTest, strict concurrency, accessibility, performance profiling, CI/CD
- Product systems — Go and TypeScript tooling, APIs, PostgreSQL, data pipelines, code generation, MCP servers, release automation
I like simple designs, decisions written down with their cost, and tests that protect behaviour rather than implementation.
