Freelancer profile translated to English.

Description

I am a fullstack developer with over 5 years of experience, specializing in process automation, system integrations, and web application development.

My niche is in projects that require connecting disparate systems: external APIs, databases, industrial devices, message queues, or SaaS platforms. I have worked with Node-RED, RabbitMQ, and OPC UA in Industry 4.0 environments, integrating complex systems for industrial clients.

On the web side, I build applications with React on the frontend and Node or Python on the backend, using relational (PostgreSQL, MySQL, SQL Server) and non-relational databases.

I adapt well to teams and also work autonomously. My entire career has been 100% remote, so asynchronous communication and self-management are natural parts of my workflow.

If you have a project that needs system integration, workflow automation, or building an application from scratch, I would be happy to talk.
