Available to hire
I’m Hidekazu Ueba, a frontend-focused software engineer who enjoys turning complex problems into delightful, maintainable interfaces. I have hands-on experience with Next.js, APIs, automation, and AI-assisted features, and I value clean architecture and thoughtful UX.
I thrive in collaborative teams, value trust and long-term maintainability, and I’m comfortable bridging language and cultural gaps (notably for Japanese users) to surface actionable feedback for the product team.
