Using Codex to take over a real Spring Boot codebase—modifying packages, fixing beans, refactoring modules, adding idempotency, and even auto‑repairing compile errors—revealed that AI can now understand project context and act as an engineering agent, fundamentally shifting Java development practices.
When over 90% of a codebase is produced by AI, the authors show how a unified "people‑align → human‑machine‑align" approach, driven by evaluation agents, transforms technical debt into incremental business work, enabling continuous refactoring, AI‑friendly standards, and a sustainable engineering environment.
When over 90% of a codebase is produced by AI, system quality hinges on constraining AI rather than speed, and this article details how a team used an agent‑based evaluation framework, unified standards, and incremental refactoring to turn 310,000 lines of AI‑written code into a maintainable, low‑debt system.
This article describes how Tubi's Android team redesigned their video player with a modular, distributed architecture—introducing PlayerContext, PlayerHandlerWrapper, and composable modules for ads, event tracking, and TTS—to improve flexibility, testability, and scalability while sharing lessons learned from the refactoring process.
This article analyses how Domain‑Driven Design and a systematic architecture‑mapping process were applied to the Tencent Video “together‑watch” service, presenting concrete domain models, architectural decisions, refactoring steps, and quantitative evaluations—including code‑size reduction, performance gains, and cost savings—while preserving the full analytical reasoning behind each choice.
This article presents a comprehensive case study of how Qunar's hotel supply‑chain team applied Domain‑Driven Design to restructure a decade‑old, highly coupled hotel information system, detailing the problem analysis, DDD rationale, evolutionary transformation process, architectural principles, implementation results, and lessons learned.
This article presents a detailed case study of the DODB digital operations platform, comparing historical and current code metrics, identifying code, project‑management and developer issues, and outlining standards, tools and refactoring practices that significantly boosted development efficiency.
The article describes how Qunar's technical director Zheng Jimin applied Domain‑Driven Design to refactor the hotel pricing engine, dramatically improving development efficiency, reducing onboarding time, and aligning product and engineering through a three‑stage strategic, tactical, and implementation process.
