About Ricardo Naoki

Ricardo Naoki H.Status: Offline
FullStack Software Engineer
Los Angeles, United States - 7:41 am local time
Senior Full-Stack & Mobile Engineer | React.js, React Native, Node.js, AWS

Hi! I’m Ricardo—a verified Upwork freelancer and seasoned JavaScript developer with over 9 years of experience building scalable, user-focused applications. I specialize in React, React Native, Node.js, and cloud-based solutions using AWS and Supabase.

I’ve worked with both startups and large enterprises (from 10 to 300,000+ employees), delivering everything from MVPs to production-ready platforms. My background includes:
• 🚀 Launching mobile apps to the App Store & Google Play using React Native (since v0.56)
• 🧠 Building scalable cloud backends with AWS Lambda, ECS, Cognito, and Terraform
• 🔐 Implementing secure auth systems, including OAuth, JWT, and social login (Google, Apple)
• 📊 Creating dashboards and real-time features using Next.js, Tailwind, and WebSockets
• 🧩 Migrating legacy systems and improving performance across full-stack apps

I built and launched Last Calorie, a cross-platform AI-powered nutrition tracking app that uses image recognition, gamification, and analytics—all from scratch. I understand the business, product, and tech sides of delivering value quickly and within budget.

💬 I prioritize clear communication, agile collaboration, and long-term client satisfaction. Whether you need a full MVP or expert help scaling an existing app, I’m ready to jump in and deliver.

Let’s build something great. Ready when you are.
