CTO: An Action‑Oriented Leader

The author, a former CTO of Ant Group and Alibaba, reflects on the qualities a qualified CTO must possess, emphasizing action over abstract thinking.

Personal Journey

Before 2004 the author studied in school. In 2004 he joined an outsourcing project to upgrade Taobao’s architecture from PHP/MySQL to Java EE, then became an intern at Alipay in 2005.

The narrative shows how Alibaba’s early cloud decisions paved the way for its later massive scale, with cloud becoming the backbone for all core services.

Three Types of Technical Leadership Across Business Stages

1. Early stage – CTO acts as a strategic partner to define direction and align technology with business goals.

2. Growth stage – CTO focuses on scaling architecture, ensuring stability, and preparing the “second curve” of future growth.

3. Maturity stage – CTO balances order and innovation, overseeing risk, organization design, and talent development.

CTO Responsibilities

Build a resonant link between business and technology.

Provide a clear vision that guides the team.

Define goals, align resources, and ensure execution.

Manage risk, turn crises into opportunities.

Design organization structures that balance order and innovation.

Develop and mentor future CTOs and technical talent.

Key Decision‑Making and Risk Management

Examples include choosing an internet‑centric architecture in 2007, scaling payment throughput for Double‑11, adopting OceanBase, handling the 527 incident, and establishing a dedicated technical‑risk department.

Organizational Design and Governance

The company uses a two‑line model: a hierarchical management line (front‑end, middle‑platform, back‑end) and a virtual technical‑committee line that connects expertise across domains.

Culture, Vision, and Talent

Technical culture emphasizes pragmatism, data‑driven decisions, and continuous learning. The author stresses the importance of “Z‑shaped” career paths for CTOs, combining technical depth with broad business exposure.

Conclusion

Successful CTOs are action‑oriented leaders who continuously align technology with evolving business needs, manage risk, design adaptable organizations, and cultivate the next generation of technical leaders.
