Reynaldo Cuenca Campos

Full Stack Python developer

Kep, Cambodia

Summary

I define myself as a good team player, who enjoys good code, and good code practices, and to learn anything new every single day. I agree with tools and processes are as important as pro-activity and understanding of business, 'you can use a gun like a stick but you will never be able to shoot with a stick like a real gun'. In the words of who knows 'untested software it's broken by definition', that's one of my favorite IT proverbs. I like TDD development environments. Always do my best to get the best solution, even over my knowledge.
