My journey in technology began with foundational courses in Web Design (2011) and Computer Maintenance & Support (2012–2014) at SENAI, which sparked my passion for the field. I built on this by starting a degree in Computer Science (2015–2016) at a public university, where I developed strong logical and analytical thinking. At the same time, I pursued a broader business perspective through studies in Accounting and Finance (2017–2019) at Universidade Estadual da Paraíba and a degree in Financial Management. After passing a municipal civil service exam, I migrated to distance learning (EAD) during the COVID-19 pandemic, expanding my academic path. Today, I’m strengthening this interdisciplinary foundation through advanced studies in Big Data (Postgraduate – ongoing) and a new Computer Science degree (ongoing), aiming to apply this diverse background to drive innovation in tech.

My academic path blends systems analysis and software engineering with ongoing studies in data science and computer science:

• 🧮 Computer Science – Faculdade Focus (Ongoing)
• 📊 Postgrad in Big Data – Univitória (Ongoing)
• 🧠 POSTGRAD IN SOFTWARE ENGINEERING – FACULDADE FOCUS (2023) – ✅ CONCLUDED
• 💻 TECHNOLOGIST IN SYSTEMS ANALYSIS – UNOPAR (2016–2022) – ✅ CONCLUDED
• 💰 TECHNOLOGIST IN FINANCIAL MANAGEMENT – UNOPAR (2017–2021) – ✅ CONCLUDED

Early studies include Web Design & IT Maintenance at SENAI (2011–2014) and an initial degree in Computer Science at a public university (2015–2016).

• ✅ Certifications: IBM Data Science Professional, IBM Linux & Shell
• 🌍 Languages: Portuguese (Native), English (Intermediate), Spanish (Basic)
