Mizuno Yuta

I am a senior full-stack engineer specializing in building scalable, secure, and high-performance web applications, automation systems, and AI-powered platforms.

I help businesses turn ideas into reliable products—from MVP development to full production systems—focusing on clean architecture, performance, and long-term maintainability.

What I can help you with:
• Full-stack web development (React, Next.js, Vue, Node.js, FastAPI, Django)
• AI integrations (OpenAI, automation, intelligent workflows, chatbots)
• API development and integrations (REST, GraphQL, Stripe, Amazon SP-API, OAuth)
• Dashboard and SaaS platform development
• Automation tools to reduce manual work and increase efficiency
• WordPress, Kajabi, and external system integrations
• Database design and optimization (PostgreSQL, MySQL, MongoDB)
• Cloud deployment (AWS, GCP, Docker, CI/CD)

Why clients work with me:
• Strong focus on business goals, not just code
• Clean, scalable, and maintainable solutions
• Fast communication and reliable delivery
• Experience working with startups, agencies, and growing businesses

I am especially experienced in building AI-powered tools, automation systems, and modern SaaS platforms.

If you need a reliable engineer who can design, build, and scale your system end-to-end, I’m ready to help.
