SUMMARY
Python developer with 15 years of commercial experience in IT, including the last 5 years fully focused on Python development.
I specialize in building scalable backend systems, microservices, APIs, data pipelines, integrations, and business process
automation. I have worked across e-commerce, scientific projects, and internal corporate systems.

I have deep expertise in Python and a modern technology stack. I follow software engineering best practices, with strong
attention to code readability, maintainability, and reliability. I also have experience with PHP, Node.js, and React.js, and am
proficient in HTML and CSS. Currently learning Rust.

Outside of work, I have a background in music education, enjoy music in general and like traveling and hiking in the mountains.

Responsible, self-motivated, and effective both independently and within a team. Open to new opportunities as a Python
Developer. I'm particularly interested in challenging product development, startups, and engineering-driven teams where I can
help build scalable, high-quality software. Authorized to work in Spain and open to on-site, hybrid, remote, and international
opportunities.
