Senior Software Developer
I build custom software as a freelance developer, working on projects for companies in Spain and worldwide.
I design the features, work out the product logic, integrate it with the API and get it ready for the people who use it. On Open V4, besides the whole interface, I handle the development and maintenance of backend functions.
Development and maintenance of software products with substantial revenue, used by companies to manage operations and installations at scale.
Vaelsys products: interface and integration development and maintenance. They have been used by
Stack of these projects
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.
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 ToolWeb 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 V4Flows and screens designed for the people who use the tool every day, including when the configuration is complex.
See example: Magic ComponentI start with the problem: who uses the tool, what they need to solve and which systems it has to live with.
We agree on scope, priorities and deliverables. I turn that need into concrete features, flows and screens.
I develop in deliveries that can be tested, with interface, logic and API connected from the start.
I debug, fix and adjust the details until the product is ready for the people who will use it.
