Freelancer profile translated to English.
Back to original languageAbout Gabriel
I work with companies that need to improve their system performance or process large volumes of data.
I combine backend development (Python, Django, APIs) with data processing (PySpark, SQL) to build complete, scalable, and reliable systems.
I have worked in demanding environments such as BBVA, optimizing data pipelines and improving system performance.
I also develop complete applications (backend + frontend) for digital products, integrating business logic and data processing.
I focus on solving real problems: slow systems, inefficient pipelines, and applications that don't scale.
If you need to improve your backend performance or process data reliably, I can help you.
