Experience building scalable and well-versioned REST APIs.

Angular with judgment: components, modules, routing, and good practices.
TypeScript, HTML5, CSS/SCSS, and a consistent styling approach.
Consuming REST APIs, managing asynchronous states, and performance.
Attention to accessibility and visual details (clean and predictable UI).
Infrastructure and environment
Deployment, stability, and smooth delivery cycles.
Docker and containerized environments for development and deployment.
Basic cloud knowledge (AWS) and common SaaS patterns.
CI/CD and a culture of small, measurable, and reversible releases.
Nice to have
AI in development
Speed, quality, and judgment to validate outputs.
Regular use of assistants (ChatGPT, Copilot, Cursor) with a practical approach.
Accelerate debugging, refactoring, and documentation without sacrificing quality.
Critical thinking: validate, test, and decide when not to use AI.

Competitive salary in line with experience.
A culture of ownership, quality, and continuous improvement.
