About Tailor Maciel

Husband, Father, Son, Pet Lover, Entrepreneur and Aspiring Computer Scientist living in South America (order may change according to the circumstance :).
I enjoy engaging with people motivated by gratitude, collaboration and commitment to results.

Work experience

I have been working for over 20 years for the main raw material distribution companies in Brazil, with steel being the main product.
My main role has been commercially managing the supply negotiations.
During this period, I've discovered more than 1000 companies in the southern region of Brazil that consume the materials we sell.
I helped these companies form lasting relationships and develop mutual interests based on trust and understanding of key market dynamics.

Academic Education

University of London

April 2019 - March 2025

Diploma of Higher Education in Computer Science

This qualification represents the successful completion of 240 credits from the University of London’s BSc Computer Science program (Levels 4 and 5), delivered online through Coursera and directed by Goldsmiths, University of London.

The curriculum emphasized hands-on programming using languages such as P5.js, C++, Python, and SQL, along with strong foundations in databases, web development, systems architecture and data science.

Key academic topics included Object-Oriented Programming (OOP), software design principles, data structures, algorithmic thinking, and the mathematical foundations essential to computer science reasoning.

My Career Path

I began my professional journey at the age of fourteen as a salesman. This early experience helped me develop strong communication skills and, more importantly, taught me the value of listening—especially to those with more experience. It made me realize that good advice can help us avoid many unproductive paths.
Over time, I learned that the most sustainable results—and the strongest relationships—come from embracing a win-win mindset.
In 2016, after earning a degree in Management Processes (Tecnólogo em Processos Gerenciais), I decided to pursue Data Science, inspired by the profound changes taking place in the job market and in how businesses operate.
Since then, I have earned certifications from Google, HarvardX, and Microsoft in areas such as IT, data analysis, and machine learning. These experiences made it clear that to truly apply this knowledge effectively, I needed a deeper foundation—leading me to immerse myself in Computer Science.
My goal is to simplify business processes, making them more agile and less bureaucratic, so that people can focus their time and energy on what is truly meaningful and productive.
