Our client is a venerable 125-year-old enterprise with deep roots in the US market and strategic operations across Shanghai, Shenzhen, and Hong Kong. As a leader in their sector, they manage a complex web of international supply chains and multi-regional business logic.
Their entire operation relies on a core, custom-built system that has been the backbone of the company for over 20 years. In a business of this scale and history, the technology isn’t just a tool—it is the digital embodiment of over a century of specialized business rules and institutional knowledge.
Challenge
01
The company’s only technical employee — its CTO of 20+ years — was leaving with zero internal team to take over.
02
The core business system had been running for two decades, built on legacy technology with extensive third-party integrations and only partial documentation.
03
A significant timezone gap required fast response with zero tolerance for downtime. A hard technical cutover could halt the business entirely.
Solution
We executed a high-intensity, structured onboarding process to first stabilize the critical environment. Our team quickly mapped the undocumented system architecture, proactively identified risk areas, and became the client's long-term development partner.

How we worked
01
Immediate Stabilization
A dedicated ramp-up team of 3 engineers immersed themselves in the live system. Issues raised on weekends and holidays were addressed immediately. Trust was built fast through rapid incident response.
02
Deep Documentation & Auditing
As our internal knowledge grew, we proactively built technical documentation from scratch, flagged critical risk areas, and advised on necessary upgrade paths.
03
Long-Term Engineering Ownership
We scaled to a team of four full-time, on-shore/off-shore engineers that now handles all day-to-day maintenance, feature development, and incident response for the legacy system.
Result
The system transitioned smoothly after the CTO's departure, with zero disruption to live business operations.
We transformed the partnership, with our team growing from "explorers" into the client’s sole dedicated technical support function.
The complex system has now run without interruption for over three years and counting, proving long-term stability.
Genuine trust has deepened the relationship. In 2023, we performed a two-week on-site visit in the US to further strengthen collaboration.
