Projects

These projects have been designed and developed by me, in some cases using images or content fragments as reference, but always creating the layout, structure and, when necessary, also the backend from scratch.

Toned by mzsn

Workout Planning & Tracking App

I built Toned by mzsn, a mobile workout app for planning training weeks and tracking progress over time. Users can set up gym, home, or rest days, build an exercise library, log sets with weight and reps during sessions, and review their workout history and personal records. The app is offline-first, with local persistence, and includes a FastAPI backend with PostgreSQL for exercise data and future sync. Backend development is ongoing as I continue building out the next version. Currently available on the App Store.

Doonity

Stay Consistent

I built Doonity, a digital product designed around the idea of helping people stay consistent. The project reflects my approach to software engineering: translating a product idea into a working application, with a focus on the user experience, interface design, and building a product that is practical and intuitive to use. React Native app, currently available on the App Store.

Viladays

Tourist Guide for Edinburgh

I developed Viladays, a digital city guide for Edinburgh, Scotland. The application allows users to explore the city, discover attractions, and find places to visit through an interactive, user-friendly experience. Built with React and Next.js, the project combines frontend development with API integration and a backend powered by FastAPI and PostgreSQL, and is deployed on Vercel.
