Master distributed debugging techniques using correlation IDs, distributed tracing context propagation, log aggregation patterns, and causal ordering to trace requests across services and identify root causes.
Apply systematic refactoring strategies to legacy codebases using characterization tests, the strangler pattern, and incremental extraction to improve code quality without introducing regressions.
Build robust error boundary strategies that catch failures gracefully, provide meaningful fallbacks, report actionable diagnostics, and prevent one broken component from crashing the entire application.
How to build custom ESLint rules for your team's conventions — covering AST selectors, rule testing, auto-fixers, and publishing a shared plugin that enforces patterns your default linter cannot catch.
A practical guide to git rebase and interactive rebase — covering when to rebase vs merge, squashing commits, rewriting history safely, fixing mistakes, and team workflows for clean commit histories.
A developer-friendly introduction to compiler fundamentals — covering lexing, parsing, ASTs, and code generation with practical examples that help you write better code, build tooling, and understand language features.
How to implement feature toggles that enable trunk-based development, gradual rollouts, and instant rollbacks — covering toggle types, testing strategies, and cleanup practices that prevent toggle debt.
How to use Git hooks to automate code quality checks, commit message validation, pre-push tests, and branch naming enforcement — with practical examples using Husky and custom scripts.
How to write Request for Comments documents that drive clear technical decisions — covering structure, audience calibration, alternatives analysis, and building consensus asynchronously.
How to implement structured logging that makes production debugging fast — covering JSON log formats, context propagation, log levels, sensitive data masking, and integration with log aggregation tools.
A deep dive into async iterators and generators in JavaScript — covering for-await-of loops, async generator functions, backpressure handling, and real-world streaming patterns.
How property-based testing finds edge cases your unit tests miss — a practical guide using fast-check to generate thousands of test inputs and verify invariants automatically.
