Graduated in Accounting from FUMEC University, I have got a 10-year-old experience in audit, finance and controllership, accountancy, and internal control. During my journey I have worked as an auditor at Big Four, an experience which has shaped my perspective about efficiency, precision and innovation. My constant will for learning had me seek new challenges. Nowadays, I am transitioning career, matching both my expertise in accounting to the progressive interest in Data Science and Big Data. As a partner at Arcontábil Assessoria Contábil, I was able to experience the complexities of the business world, developing essential management skills. Beyond my work and fatherhood, I dedicate myself to programming, particularly in Python, sharing learnings and projects on GitHub and Medium. Now, as a postgraduate in Big Data & Data Science from PUC-MG, I am determined to apply my experience in new contexts and boost my new career in Data Science.I invite you to connect with me to follow my journey of transformation and collaboration in this fascinating universe of data.https://github.com/joaomarcelofchttps://medium.com/@jmfonsecacunhaPortfólio de projetos: https://github.com/joaomarcelofc/Joao_Portfolio
