About

Developer by trade,
scientist at heart

I am a Senior Front-End Engineer with over 6 years of experience architecting and building high-performance web products. My journey has led me to write and refactor large codebases across diverse industries like fintech, IoT cataloging, e-commerce, and comic entertainment platforms.

I hold a B.Sc. First Class Honours in Microbiology from the University of Lagos (CGPA 4.74/5.00). My academic pursuits sparked a deep fascination with computational biology and genomics, leading to hands-on experience in genome annotation and characterization of mycobacteriophages.

I believe that frontend engineering and microbiology research share a core methodology: analyzing complex, interconnected systems, and translating that complexity into clean, modular, and human-interpretable patterns. Whether I'm refactoring a 25,000-line React codebase or comparing phage genomes with Python, my goal is always to deliver precision, performance, and structure.
