About me
About About me

Languages_
- Spanish Native
- English C1
I am a backend developer from Ecuador focused on building robust APIs with Python. I have experience using Django for complex admin panels, but the language's versatility allows me to adapt easily to other frameworks like FastAPI.
For data persistence I use SQL; choosing Postgres for high-concurrency servers and SQLite when it comes to local or desktop applications. Apart from this, I have also explored the use of Golang for microservices or side projects, and I am capable of building web or mobile interfaces for users.
My usual programming environment is Linux, Debian; so I am familiar with the terminal. This has allowed me to gain a deep understanding of the OS and facilitate cloud deployments.
Finally, with my C1 English level I have no problem reading documentation and integrating into a team, all while continuing my self-taught learning.
