Jun 2024 - Present • 2 yrs 4 mos

I specialize in backend engineering with Java (Spring Boot) and PHP (Laravel/Yii2), supported by frontend expertise in ReactJS. My background includes architecting microservices, developing APIs serving 50K+ users, and leading deployments of enterprise systems such as a national multi-school management system adopted by 200+ institutions. More recently, I have been designing AI-driven automations and intelligent agents that streamline workflows, enhance decision-making, and reduce manual effort across organizations. By combining AI tools, APIs, and custom automation frameworks, I create systems that are not just functional, but adaptive and future-ready. Beyond coding, I bring strengths in cloud technologies (AWS, Docker, CI/CD) and cybersecurity (Vulnerability Assessment, Pentesting, API Security), ensuring the systems I build are both scalable and secure. Highlights: Built and deployed mission-critical applications reducing downtime by 30% Designed fintech APIs consumed by mobile apps & USSD serving non-smartphone users Delivered custom HR, POS, and e-commerce systems that improved business efficiency I thrive at the intersection of technology and impact — solving complex problems, mentoring teams, and delivering solutions that drive real business results.
