About

End-to-end product development experience

I am a Full Stack Developer with more than five years of experience building web and mobile applications. I work mainly with React, TypeScript and Node.js, developing interfaces, APIs, business logic and database integrations.

I also led the technical development of a PropTech platform and built n8n workflows for classification, document validation, and financial, environmental and matchmaking RAG agents. My focus is integrating AI and automation into functional products by combining user experience, business logic and contextual retrieval.

I am looking for Full Stack, Backend, Frontend or applied AI opportunities within remote teams.
