About the Author.
I am a Cybersecurity Expert & Software Engineer
With expertise in Cybersecurity, Software Engineering, and Web Development, I specialize in creating secure systems and custom solutions to address digital challenges. My experience ranges from conducting penetration tests and designing automation tools to developing web-based GUI desktop applications using C++ with the Qt framework and Python. I’ve built my portfolio website using Laravel and developed a CRM to streamline internal operations at my company. Additionally, I’ve led efforts in compliance with ISO 27001 and LGPD standards, and built research-driven malware in C++ to test network vulnerabilities.
In game development, I created a Super Mario Bros clone using C++ and SFML, and a horror game in Unity and C#. As a freelancer, I build websites using PrestaShop and PHP, developing custom integration modules like automated shipping calculators and payment gateways for businesses. My combined expertise in e-commerce platforms, secure software development, and game design allows me to deliver scalable and optimized solutions across a range of industries.
