Frequently Asked Questions
Everything you need to know before we work together.
Project builds, fractional mobile lead, and architecture or delivery reviews — anywhere from a few weeks to a long-term engagement. If you are not sure which one you need, that is usually what the first call is for.
Yes — most of my work has been joining something already running. Auditing an app that has become hard to change, unblocking a release that keeps slipping, or taking over a codebase whose original team has moved on.
Embedded in your process, not alongside it — your board, your standups, your review cycle. I am based in Seville and work remotely, with hours that overlap both European and US teams.
Heavily, and deliberately. I designed, built and shipped mnite to both app stores in two months working solo, with Claude across prototyping, backend and the Flutter app. It does not replace engineering judgement — it removes the work that was never the hard part.
