Full-stack software engineer building fast, accessible, scalable web systems — from real-time dashboards and marketplace platforms to consumer apps. Front-to-back, with equal care for engineering quality and the user experience.
About
I'm Samuel Onwuka — a full-stack software engineer with 4+ years shipping production web systems across marketplaces, dashboards, booking platforms, and real-time consumer apps.
My core stack is React, Vue, Next.js, and Nuxt.js on the frontend, with Node.js and Python on the backend. I care deeply about component architecture, UI performance, and the quality of the experience end users actually feel.
I think in systems. I write code that scales, document decisions that matter, and collaborate closely with design and product to ship work that moves the needle — not just work that ships.
