Desenvolvedor de software

In this position, I successfully developed and delivered great products to my freelance clients. The jobs goes from web scrapers, crawlers, and compressing algorithms, all the way to trading strategies to automate my client's trades. Everything was done using Python and object-oriented programming with Data Driven approach to honor my Data Science and Data Analytics background from DataCamp with Pandas, Matplotlib, Numpy and Seaborn driving each and every job I did. As I had too many clients with big jobs, it was my responsibility to deal with every project the best way possible and to reach this I used Jira together with the Agile approach to plan each and every step, I can say for sure that this alone made me a better software developer. When working with Upwork clients, I understood the clients needs to have good responses and in time ones, so every client of mine had access to my phone number to reach me anytime they needed, and if something failed or they needed my help, I was there anytime for their journey. Even with clients who did not hire me, if the project that they were doing could leverage my abilities to the next level, my approach was to develop the code and save it for later, because if another client ask me for a similar project I would be ready for it in no time. Some of these projects can also be seen in my GitHub profile. I
