Summary

Senior🎓
Top SchoolMasao Fujii is a seasoned Database Technical Lead and PostgreSQL committer based in Tokyo with over 16 years of hands-on experience and a 20-year career footprint in database engineering. He has led modernization and openization of mission-critical core banking systems, architected migrations from mainframe data stores to open RDBMS, and driven company-wide best practices and technical sales enablement at NTT DATA. As an active contributor to PostgreSQL, he not only implements replication and core features but also feeds real-world operational feedback back into the community to address persistent production issues. Now serving as Director at SRA OSS while continuing his committer role, he blends deep technical expertise with cross-organizational leadership to make large-scale migrations sustainable. Outside work he wryly notes being “maybe a good husband & father,” hinting at a grounded, team-focused approach to both engineering and life.
