The author argues that the most critical skill for senior developers is the ability to independently design and deliver large, complex systems, emphasizing thoughtful architecture decisions, trade‑off analysis, and proactive problem‑solving throughout a project's lifecycle.
The author reflects on a recent technical design presentation, analyzes strengths and gaps in the architecture process, and argues that only a top‑down macro view paired with bottom‑up micro‑level detail can prevent architects from drifting into vague, non‑actionable designs.
The article describes Tencent Channel’s high‑performance Feeds flow system, built on a three‑layer logical‑proxy‑storage architecture that separates reads and writes, uses distributed caches and timestamp‑based pruning to cut query load fifty‑fold, and combines public indexes with user‑specific reads to enforce visibility controls.
This article explains how to transform product requirements into robust technical architectures by addressing uncertainty through strategic principles—suitability, simplicity, evolution—and tactical guidelines covering high concurrency, high availability, and business design, illustrated with logical and physical diagrams.
This article explores how to transform product requirements into robust technical architectures by addressing uncertainty, outlining strategic principles—appropriateness, simplicity, evolution—and tactical guidelines for high concurrency, high availability, and business design, while illustrating logical and physical architecture diagrams and offering practical design recommendations.
This article explains why many technical proposals feel shallow, defines breadth and depth characteristics, introduces a four‑part methodology (essence, contradiction, system, evolution), and demonstrates its application through three concrete solution case studies.
This article outlines a detailed software development workflow—including requirement review, technical design review, coding, code review, testing, deployment, and post‑release retrospection—providing practical checklists, templates, and best‑practice recommendations to improve product quality and team efficiency.
Compiled from public sources by Ju Jianhua, this article examines how trading platform architectures evolve with business growth, using a series of illustrative diagrams to highlight key components, design patterns, and considerations for building scalable and secure exchange systems.
