Omar Yesid Mariño

Software Python Engineer

BOGOTA, Colombia


With over 20 years of experience in software development and a focus on Python since 2014, I am very interested now in the fields of Machine Learning, Data Science, and AWS Cloud Computing.

I follow a well-defined coding style, using PyCharm as my preferred IDE. I strictly adhere to the PEP 8 style guide, leveraging tools such as Flake8, SonarLint, Pylint, and Mypy for linting, Black as auto-formatter, and Tabnine for AI-powered code completion.

Skilled in a variety of technologies, including Django, Flask, FastAPI, Python, AWS, Web Development, CloudFront, MySQL programming, Amazon EC2, Linux System Administration, Amazon S3, Google APIs, Meta APIs, PostgreSQL, NoSQL databases, GIT, Docker, Kubernetes, Cloud Computing, Scrapy and Selenium, I am well-equipped to tackle a diverse range of projects and challenges.
