Tools

What I use.

My technical stack and the tools I actually open every day.

Mobile

Language & interface

Swift

The language behind every iOS app I ship, from business logic to the last view.

since 2021 · 5 years

The declarative framework building every interface, from prototype to production.

since 2021 · 5 years

Data & sync

since 2025 · 1 year

Charts

Native charts to visualize data inside an app, no third-party dependency.

since 2025 · 1 year

Concurrency

async/await and actors, for parallel code that's safe by construction, no data races.

since 2024 · 2 years

Observation

@Observable-based state tracking for SwiftUI, no ObservableObject boilerplate.

since 2023 · 3 years

Combine

The reactive glue between data layers and UI, before Observation came along.

since 2022 · 4 years

Architecture

Clean Architecture

Separating business logic, data and UI so each layer stays testable on its own.

since 2022 · 4 years

MVVM

The pattern behind most of my screens: a view, a view model, nothing in between.

since 2021 · 5 years

MVVM-C

MVVM with a dedicated coordinator for navigation, keeping that concern out of the view models.

since 2022 · 4 years

Testing

Web

Frameworks

Signing in with a Google account, as an alternative to Apple Sign In.

since 2025 · 1 year

Tools

Development

Xcode

since 2021 · 5 years

TestFlight

Getting builds to beta testers before release, with their feedback and crash reports.

since 2025 · 1 year

Instruments

Apple’s profiler, for hunting down memory leaks, slowdowns and energy drain.
