ryuuzaki
Senior Backend Engineer/Architect
I’m a backend-focused/crypto engineer with a strong foundation in designing scalable, maintainable systems (especially in distributed architectures and blockchain-integrated backends).
Over the years, I’ve led teams through large refactors, moving legacy codebases toward clean, domain-driven designs, while still keeping business delivery on track
I enjoy mentoring developers, and simplifying complex problems, trying to transmit the same mindset into the team
I’m naturally curious, I like understanding how things fit together at both the technical and business/product level, which helps me spot patterns and improve processes across teams.
