About

As a Cybersecurity Engineer with over 5 years of experience, I specialize in securing complex cloud environments, implementing robust penetration testing, and managing vulnerability assessments. I have effectively enhanced infrastructure security by applying best practices in cloud security (AWS, GCP), containerization (Docker, Kubernetes), and threat mitigation strategies. My expertise also includes containerization and securing Docker environments, where I have successfully implemented security measures to reduce vulnerabilities and ensure compliance. I am passionate about building secure, scalable systems that prioritize performance and security. Additionally, I have 6+ years of software development experience, building secure, scalable applications with a focus on performance and security. My proficiency in Python, Django, Flask, FastAPI, GoLang and ReactJS has allowed me to create solutions that align with security and development best practices.
