Custom development

Web development with React and Node in own code

We build custom web apps with React and Node, from scratch and in own code. Fast, secure and independent of low-code platforms. You control the code, we make it grow.

Web development with React and Node in own code

Custom web application development with React and Node matters when application development with React and Node in own code versus third-party low-code solutions. Before selecting tools, we define the journeys, data and decisions that must remain under your company's control.

We work from Barcelona and Madrid and remotely with teams across Spain, Europe, LATAM and the United States. The process combines decision sessions, verifiable releases and documentation so progress stays visible.

We hand over code, repositories, configurations and documentation in accounts owned by your company. You can therefore audit, evolve or change supplier without relying on private access or licences.

We build custom web apps with React and Node, from scratch and in own code. Fast, secure and independent of low-code platforms. You control the code, we make it grow. That is why we prioritise a maintainable, measurable solution ready to evolve without rebuilding its foundations.

THE CHALLENGE

The challenge of React and Node web development

low-code frameworks and SaaS limit evolution and code ownership

  • Outdated stack and vulnerabilities

    Old React and Node apps accumulate obsolete dependencies and security flaws nobody fixes.

  • Browser performance

    Over-rendering views and heavy bundles degrade the experience without the business noticing.

  • Missing automated tests

    Without front and back tests every deployment introduces regressions found only once live.

APPROACH

How we fix building scalable custom applications

We move forward with measurable decisions and releases that already add value.

  1. Codebase review

    We analyze project structure, dependencies and conventions to detect debt and breaking points.

  2. Development standards definition

    We set lint, typing and folder rules applied uniformly by the whole team.

  3. Implementation with code review

    We build features through pull requests reviewed by a person before each change is merged.

  4. CI with tests and deployment

    We automate tests and deployments so every change is verified and traceable end to end.
