My Journey

Philosophy and Focus

  • Software Engineering student at PUCPR.
  • Driven by the motto "Learn something new every day!", with a passion for creating scalable and innovative software solutions.
  • Started my programming journey in 2022 with JavaScript, deepening my studies in Python in 2023.
  • Currently focused on studying and developing innovative, scalable projects with Java (Spring Boot), React, NextJS, Docker, Terraform, and AWS.

Resilience and Adaptation

  • My mindset was forged in soccer, treating the sport (and programming) with dedication, resilience, and teamwork.
  • I learned to face frustrations and never give up, a skill I apply daily when debugging code.
  • Furthermore, my resilience and adaptability were tested during an exchange program in Utah, USA, overcoming adaptation challenges and winning a regional soccer championship.
  • I consolidated my English fluency during this international experience.

Objectives

  • Practical experience building robust full-stack applications like ZapTrack and E-commerce APIs, utilizing Java (Spring), Next.js (TS), Docker, and AWS.
  • At Vivo, I engineer scalable data solutions using Python (FastAPI), SQL Server, and complex ETL pipelines to solve critical business problems.
  • Gain experience building secure, scalable, and helpful software that solves real-world problems, laying the foundation to grow my own company, Nex Solutions.
  • Deliver innovation, dedication, and care in all solutions created.
