Everything I publish here is free and open source, and always will be.
But if something helped you and you feel like buying me a coffee (or a Monster) so I can spend
more nights studying and building cool things for the community, that makes me very happy <3

I build data products, automated workflows, and reliable reporting that connect technical work with business needs.

My background combines 12+ years in projects, operations, process improvement, and stakeholder management with hands-on work in data analytics and engineering. In my most recent data role at CEPA Mobility Brazil, I supported Johnson & Johnson's SAFE FLEET data operations across 10 countries in APAC, Japan, and EMEA.

I work with Python, SQL, Pandas, Power BI, Excel, Power Platform, ETL, data quality, dashboards, reporting, and process automation.

I am now expanding this foundation into cybersecurity through the Senac RJ and Cisco training path, with focus on systems, networks, defensive security, incident response, and secure data operations.

Cybersecurity at Senac RJ is in progress in 2026. The 100-hour Cisco course prepares students for the Cisco Certified Support Technician Cybersecurity path.

Current course topics:

• Windows and Linux
• Networking fundamentals
• Common threats, attacks, and vulnerabilities
• Network, server, and application security controls
• Firewalls and security policies
• Cryptography
• Data confidentiality and availability
• Cisco Packet Tracer labs
• Attack and defense simulations

• Cisco Packet Tracer: design and validation of three-branch topologies, serial WAN, OSPF area 0, DHCP, DNS, HTTP, VLANs, ACLs, SSH, and wireless networks.
• Networks and protocols: IPv4, subnetting, routing, WAN, VLANs, DHCP, DNS, HTTP, and testing with ping and traceroute.
• Wireshark: packet capture and traffic analysis in controlled labs, using filters for ARP, DNS, TCP, and HTTP.
• CLI: Cisco IOS configuration and terminal diagnostics with commands such as show, ping, and traceroute, plus Windows and Linux commands.
• Bash: navigation, files, permissions, text filters, logs, and lab task automation.

The practical work is documented in the SENAC-CISCO repository, with a LAN-WAN and security branch, a Copa Norte network branch, and the course documents.

My broader learning roadmap includes:

• Systems and scripting: Linux, Windows, Bash, PowerShell, and Python
• Network analysis: TCP/IP, subnetting, DNS, TLS, Nmap, Wireshark, and tcpdump
• Defensive security: hardening, firewalls, IDS/IPS, EDR, SIEM, SOAR, logs, and incident response
• Application and cloud security: OWASP Top 10, IAM, AWS, Azure, and GCP security concepts
• Governance and risk: NIST, CIS Controls, vulnerability management, and security policies
• Practice: Cisco labs, CTFs, threat hunting, digital forensics, and blue-team exercises

• Data Analyst at CEPA Mobility Brazil, supporting global data operations, quality checks, dashboards, and reporting from July 2025 to August 2026
• 10-country operational scope across APAC, Japan, and EMEA
• 12+ years leading audiovisual projects, teams, budgets, suppliers, and international clients through Varanda Vista Filmes
• Open to Data Analytics, BI, Data Operations, Junior Data Engineering, Data Quality, and entry-level Cybersecurity opportunities

From audiovisual storytelling to reliable data and security systems.
