I am a software engineer specializing in backend development, API security, cybersecurity, and AI integration.
I design and build secure, scalable, and data-driven systems, with hands-on experience in web application security testing, secure network design, and Artificial Neural Networks (ANNs).
My work spans backend engineering, Zero Trust API architectures, OWASP Top 10 mitigation, and intelligent system design, with a strong focus on real-world impact and measurable results.
