IT Generalist (Development, Infrastructure & Networks) actively transitioning into Backend Development, Data & Cybersecurity, based in Minas Gerais, Brazil 🇧🇷

I'm the IT reference at a mid-sized accounting firm, handling:

• Infrastructure & Networking — MikroTik, multi-ISP failover, Windows Server, Active Directory
• Support & Business Systems — troubleshooting accounting software (Domínio Contábil, Jettax, Sieg)
• Automation — Python and PowerShell scripts for monitoring, reporting, and process automation

This hands-on infra/networking background is also the foundation for my growing interest in Cybersecurity.

• Backend Java — Spring Boot, Spring Web, JDBC, JPA/Hibernate, JWT, REST APIs
• Docker & Maven
• Advanced SQL
• Cybersecurity fundamentals
• Started a Systems Analysis and Development (ADS) degree at Uninter (EAD) in August, 2026

• Python — process automation, web scraping, API integrations, data pipelines
• Data Analysis — cleaning, transformation, EDA, visualization (Pandas, NumPy, Matplotlib)
• Reporting — Power BI dashboards, structured CSV/Excel reports
• Machine Learning — practical projects with Scikit-learn, Scaler and SMOTE

My technical foundation: Technical High School in IT (IFSMG) + ~1.5 years of an unfinished Computer Networking degree, with hands-on Packet Tracer experience.

1. Backend Development (Java/Python)
2. Fullstack Development (Java/Python/JS-TS)
3. Data, Machine Learning & related fields
4. Cybersecurity
5. N1/N2 Support (as a fallback)

Some projects were developed with the support of modern tools and AI-assisted workflows, always with a focus on understanding, validating, and correctly applying the results.

• Backend API projects (Java/Spring Boot)
• Data analysis and data preparation projects
• Python scripts focused on automation, data manipulation, and reporting
• Well-documented projects with clear objectives and outcomes

Open to Junior/Internship opportunities in Backend, Data, or Cybersecurity — and always happy to talk IT infrastructure and networking, where I have solid, proven hands-on experience.
