What I'm looking for

I am seeking a role leveraging web development and data skills in a collaborative, growth-oriented company where I can contribute to product accuracy and operational efficiency.

I am a detail-oriented Computer Science graduate with hands-on experience in data annotation, IT support, and full-stack web development. I have delivered accurate labeled datasets for AI/ML models and supported secure IT operations during an NYSC placement.

As a store executive and former manager, I improved inventory workflows, coordinated nationwide stock transfers with 100% compliance, and increased client retention by 30% through strong customer relationships and training. I have trained over 100 students in Microsoft Office and introductory web development.

I hold certifications in full-stack development and responsive web design and am proficient in HTML5, CSS3, JavaScript, Excel, and basic SQL. I work independently with minimal supervision and focus on applying technology to solve business problems and support growth.
