What I'm looking for

I seek roles combining cybersecurity and full-stack development where I can build secure, AI-augmented, cloud-native systems, drive DevSecOps practices, and grow into technical leadership.

I am a cybersecurity-focused full-stack developer with hands-on experience building secure web and cloud-native applications, AI-integrated solutions, and decentralized systems. I combine ethical hacking, secure coding, and scalable architecture to deliver resilient software.

My work includes developing AI-powered e-commerce platforms on Shopify, building an RAG news aggregator using Google Cloud AI APIs, and creating dApps on the Celo blockchain. I have performed penetration tests with Kali Linux, Burp Suite, OWASP ZAP, and Metasploit, producing actionable security reports and measurable hardening improvements.

I thrive on rapid prototyping and automation, reducing development cycles and improving collaboration through tooling like Cursor and SharePoint. I seek to apply my mix of cybersecurity, cloud, and full-stack development skills to build secure, innovative products that scale.
