Legacy systems are not liabilities — they are accumulated knowledge, built over decades.
By decoding the structure and design philosophy of existing systems, I architect the optimal migration path to modern infrastructure. Respecting what already works, protecting business continuity, and rebuilding with purpose: that is the expertise developed across 30+ years in the field.
Experience spanning large-scale enterprise deployments — including systems serving tens of thousands of end users across industries.
Areas of Expertise
Background
Enix (1980s)
At Enix, contributed to the planning and development of titles including "Zaurus," "Earth Warrior Rayza," and "The Three of the Galaxy." Gained hands-on programming experience on SUN-3 workstations and built a solid technical foundation in UNIX-based system design — the era that shaped a deep instinct for how software systems are structured and maintained over time.
Gupta Technologies Japan (Founding Era)
Joined Gupta Technologies Japan during its founding period — the company that introduced SQLWindows 4GL development to the Japanese enterprise market. Delivered system implementation and technical support across numerous large-scale deployments, gaining firsthand insight into how organizations adopt, come to depend on, and eventually outgrow legacy systems. That understanding — of why legacy systems are built the way they are — is the foundation of every modernization engagement today.
Current Practice
Current practice focuses on direct client engagements for legacy system modernization: deep system analysis, phased migration planning, and hands-on rebuilds using Laravel and Java Spring. Complemented by MySQL performance tuning, Python-based data analysis, and AI-assisted development advisory for enterprise DX initiatives.
Fit & Engagement
Engagements are designed for organizations ready to make a sustained commitment to systems that are central to their operations. The work spans deep system analysis, phased migration planning, implementation oversight, and ongoing technical advisory — not a one-time intervention.
