    I'm a software developer with most of my experience stemming from my involvement at Mercadolibre, where I developed productive APIs and other internal usage tools for the company. This granted me lots of back-end development experience in Python, but most of all I gained an understanding on how to develop a product from start to finish, including its original design, development and deployment, and maintenance. This demanded research and interaction with potential customers at first, then beta testers, and finally active users.
