Experience

CS50 Web Projects

Developed some projects from Harvard CS50 Web. This course picks up where Harvard CS50 leaves off, diving more deeply into designing and implementing web apps with Python, JavaScript, and SQL using frameworks like Django, React, and Bootstrap.

Flask Blog

https://youtu.be/Ah2jD-alCe4
A fully-featured blog was done as the final project for the Harvard CS50 course and carried out following Corey Schafer's tutorial about it. It allows for user registration, login, and logout, among other features. Users can publish their posts, edit them and delete them, as well as upload their profile picture, change it, and edit their username and email. Publications are divided into five posts per page. It has custom 403, 404, and 500 error messages and stores everything in an SQLite database.

Python and Data Analytics at Alkemy.org

In this course, we learned tools and techniques for ETL and Data analytics.

The main tools used were:
• Python with Pandas, logging, requests, decouple, SQLAlchemy, and venv
• PostgreSQL
• Apache Airflow
• Apache Hadoop

The course is divided into three main projects:
• Admission challenge (ETL project).
• Creating Dags with Apache Airflow.
• Processing Big Data files with Apache Hadoop.

Led by an expert in the field as a mentor. Organized using Agile methodology, with weekly sprints, daily meetings, and Jira tickets.

The full description of the three projects can be found in the project's link.
