# Projects & Work

> Mobile apps shipped to the Play Store, live web platforms for real clients, and machine-learning models - grouped into three areas.

The portfolio groups work into three areas. Each has its own page with the individual projects, the stack used, and links to the live app, store listing or repository.

- [Mobile development](/projects/mobile) - Flutter and Dart apps, including two published on the Google Play Store.
- [Web development](/projects/web) - React, Next.js and TypeScript platforms running in production for clients.
- [Data science and machine learning](/projects/data) - deep-learning and signal-processing projects in Python and TensorFlow.

## How the work is usually shaped

Most engagements start as a single product problem - a delivery flow, a booking system, a detection model - and end with something running in front of real users. I work end to end: architecture, implementation, release, and the follow-up iteration once people start using it.

More repositories, including experiments that never became products, are on [GitHub @Codernointed](https://github.com/Codernointed). To discuss a specific project, use the [contact page](/contact).
