Cloud Security Architect
I’m a Cloud Security Engineer & Architect who builds systems that don’t just run they defend, adapt, and scale. My focus is on secure cloud design, automated defense, and intelligent threat response across AWS, Azure, and hybrid environments. I merge DevSecOps principles, Zero Trust frameworks, and AI-driven security analytics to transform cloud infrastructures into resilient ecosystems.
Every architecture I design follows one core rule security must move faster than risk. From IaC blueprints to real-time anomaly detection, my work blends engineering precision with strategic foresight. I’m fluent in automation, observability, and compliance engineering, and I continuously evolve systems to stay ahead of emerging threats including quantum-era risks.
Designed and implemented a Zero Trust security model for AWS environments using IAM, SCPs, and network segmentation.
Developed a machine learning model to detect anomalous behavior in cloud logs with 94% accuracy.
Automated CIS benchmark compliance checks across AWS accounts, reducing audit time by 70%.

Led R&D on a system to detect quantum bit (qubit) errors using behavioral AI models—laying the foundation for resilient quantum-secure architectures.
Developed an app to help Nigerians locate nearby fuel stations with live price and availability info. Designed to reduce stress during fuel scarcity periods.
Built a serverless API that fetches and filters book data from Google Books API. Supports keyword search, price filtering, and paginated responses.

Worked on the Development of an AI-driven border monitoring system that analyzes trade data, detects anomalies, and helps prevent smuggling and illicit activities in real-time.
Developed a Python-based tool that automates security checks across AWS environments, identifying misconfigurations and compliance issues to enhance cloud security posture.
Built an AI-driven trading bot that integrates real-time news analysis and machine learning algorithms to make informed trading decisions in dynamic market conditions.
