Hello! I’m a Full-Stack Web & Mobile Engineer based in Japan, with strong experience in AI-powered applications and real-time systems.
I build production-ready web and mobile applications — not demos or PoCs.
My core expertise covers modern web development (React, Next.js, TypeScript), mobile apps with Flutter (iOS / Android / Web), and backend APIs, with hands-on experience in AI integration, live streaming, and high-load systems.
What I help clients with:
• Web application development
– React, Next.js, modern frontend architecture, performance optimization, and scalable UI design
• Mobile app development
– Flutter for iOS / Android / Web, including authentication, widgets, DRM-based media playback, and production releases
• AI-powered features
– Azure OpenAI–based content generation, automation, and API-driven AI workflows
• Real-time & streaming systems
– WebRTC, HLS, live streaming platforms, and scalable backend architectures
• Reliable project execution
– clean code, clear communication, and on-time delivery
Selected experience:
• Built and maintained large-scale web and mobile applications used in real production environments
• Developed and operated a live streaming platform using WebRTC and HLS, handling high concurrency and long-term operation
• Implemented AI-driven features using Azure OpenAI Service in real-world applications
• Delivered projects both as a solo engineer and with small, trusted teams depending on scope and timeline
How I work:
I personally stay hands-on with architecture and implementation.
For larger scopes, I scale delivery with a small, trusted team while keeping technical decisions, reviews, and code quality consistent.
If you’re looking for an engineer who can turn complex requirements into a stable, maintainable product, I’d be happy to help.
