Antonyo Andrei, freelance software developer. Custom software for companies.

Work directly with a freelance developer to build a new tool or improve an existing product. Web and mobile software and API integrations for businesses in Spain and worldwide.

• Custom software

  Internal tools to manage operations, visualise data and connect your business systems. I build the product logic and integrate it with your APIs.

  See example: Site Design Tool
  

• Web and mobile apps

  Web apps with React and TypeScript, and mobile apps with React Native. I develop new features and maintain existing products, from the interface to the backend connection.

  See example: Open V4
  

• Interface design

  Flows and screens designed for the people who use the tool every day, including when the configuration is complex.

  See example: Magic Component
  

How I work

1. Understand

   I start with the problem: who uses the tool, what they need to solve and which systems it has to live with.

2. Propose

   We agree on scope, priorities and deliverables. I turn that need into concrete features, flows and screens.

3. Build

   I develop in deliveries that can be tested, with interface, logic and API connected from the start.

4. Refine

   I debug, fix and adjust the details until the product is ready for the people who will use it.
