Software engineer with 8+ years designing and building robust, scalable systems, from the domain model to the interface. I work with hexagonal architecture, DDD and CQRS, and I care about code maintainability and helping teams ship with less friction.

Own products
I design, build and ship my own apps, from idea to product, with the same engineering care I bring to my day job.
- ToneMate. A native macOS writing assistant. It rewrites, translates, proofreads or replies right where you are writing, with a model on your Mac or your own API keys. It dictates speech to text too.
- GoForIt. Your personal performance system: training, nutrition, sleep and recovery in one place. For iPhone and Apple Watch, connected to Apple Health, Google Health, Strava and Garmin.
- Pedalytics. Wear and maintenance for your bike. Connect your rides, assign each component to its bike and see how much each route really wears your gear: it separates distance ridden from mechanical load.
