Freelancer profile translated to English.

Description

👋 I'm Maria, a full stack developer with over 5 years of experience designing and maintaining efficient, scalable digital solutions focused on process automation.

I have worked in corporate environments for companies like Telefónica Tech and Getronics, developing robust APIs with Node.js and NestJS, modernizing frontends with React and AngularJS, and optimizing environments with Docker, CI/CD (GitLab, Jenkins), and Oracle and MongoDB databases.

Currently, I help companies, entrepreneurs, and professionals to:

Automate repetitive tasks with Zapier, Apps Script, or code (Python, JavaScript)

Extract structured data through legal and efficient scraping (Idealista, Amazon, Wallapop…)

Create intelligent dashboards connected to their data (Google Sheets, Airtable, APIs)

Develop bots or microservices that optimize decision-making

I connect the technical world with practical and understandable solutions, always focused on delivering real value in the short term.

If you have a manual workflow that wastes your time or need a technical project with a long-term vision, I'd be happy to help.
