Browser Internals

Deep dive into Chromium's multi-process architecture, the rendering pipeline (Style / Layout / Paint / Raster / Composite), GPU compositing, and V8 engine mechanics. Build a complete mental model from request to pixel.

�

JavaScript Deep Dive

From execution context, scope chain, and closure nature to V8 JIT compilation and GC. Understand the evolution of async programming and memory models to write predictable, high-performance code.

⚛️

Frameworks & Ecosystem

Analyze React Fiber's interruptible chain rendering, Vue 3's Proxy reactivity, and the design evolution of state management from Flux to Zustand. See the engineering trade-offs behind framework abstractions.

⚡

Performance Engineering

Centered on Core Web Vitals (LCP / INP / CLS) and the rendering pipeline, decompose waiting, blocking, and redundant work on the critical path. Produce actionable optimization checklists.

✅

Testing Engineering

Cover the full load-testing methodology, TPS / P95 metrics, layered bottleneck diagnosis, and degradation / circuit-breaker validation. Build a verifiable quality-assurance system.

🤖

AI Engineering

Explore AI-assisted programming practices, prompt engineering methodologies, code generation quality assessment, and AI toolchain integration strategies. Build human-AI collaborative engineering workflows.

🚀

Career System

From T-shaped to π-shaped capability models, growth paths from junior to architect, and methods for building technical influence. Provide quantifiable advancement frameworks, not vague advice.
