About Pol

I am a backend developer specializing in Python and Django, with 5 years of experience in creating and implementing web applications and SaaS platforms. I also have experience developing APIs and microservices with FastAPI. I have implemented authentication systems, background tasks, automated processes, performance optimization, and external API integration, deploying applications on AWS and Google Cloud.

My data management experience includes designing and maintaining SQL and NoSQL databases, optimizing schemas and queries, and handling structured and unstructured data. I have developed data scraping, cleaning, and automation processes for analysis and predictive modeling.

I also have knowledge of web and graphic design, with hands-on experience in HTML, CSS, Django templates, AngularJS, and HTMX, which allows me to collaborate effectively with frontend teams and develop simple, product-oriented interfaces.
