Freelancer profile translated to English.

Description

I develop and maintain web applications, both starting from existing projects and creating solutions from scratch.

I help companies and freelancers solve technical problems (production errors, failing APIs, integrations, automations), and also to launch well-defined new projects, focusing on practical and maintainable solutions.

I work primarily with backend in Node.js, frontend in React, and serverless architectures in AWS (Lambda and API Gateway).

I adapt to projects from scratch or improvements on existing systems, always with a clear scope, direct communication, and prices adjusted to the actual work.
