Engineering Ideas Into Impactful Web Experiences.
Senior Frontend Engineer with 6+ years of experience building scalable, user-focused web applications using React, TypeScript, and Redux. I turn complex ideas into seamless digital products that deliver measurable results.

Who I Am
Crafting digital experiences through code and creativity
Hi 👋, I'm Oghenemarow Macaulay, a Senior Frontend Engineer 👨🏾💻 with 6+ years of experience in the modern web stack: TypeScript, React ⚛️, TailwindCSS, Redux/Zustand & ShadCN. I have a passion ❤️ for developing user-friendly interfaces that are visually stunning and highly functional.
My proficiency in TypeScript enables me to write clean, efficient, and maintainable code for enterprise scale. Alongside TypeScript, I specialize in Next.js 🚀 architecture, delivering Server-Side Rendered (SSR) applications. My focus on performance is proven: I successfully architected a frontend that achieved a 30% reduction in load times, leading directly to a 40% increase in user engagement.
I have a deep understanding of Tailwind CSS, a utility-first framework that allows me to create responsive designs quickly. Crucially, I am a fierce advocate for user-centric design and have successfully driven projects to achieve a 100% Lighthouse Accessibility Score 💯.
Overall, I take great pride in creating user-friendly interfaces that solve real-world problems. If you’re looking for a Senior Frontend Developer who combines technical excellence with measurable business impact, I would be excited to work with you!
