Senior Software Engineer based in Tokyo with 10+ years of experience building high-load backend systems and distributed architectures.
I specialize in designing and scaling microservices using Python, Go, and Rust. My work focuses on performance, reliability, and clean system design — from early architecture decisions to production optimization.
Core areas:
- High-load RESTful APIs
- Microservices & distributed systems
- Performance optimization
- System design & architecture
- Technical leadership & SDLC ownership
I care about building systems that are simple, scalable, and maintainable.
Currently exploring deeper Rust adoption and systems-level performance engineering.
