Cleanup & Refactor

Scan codebase for technical debt and code smells. Clean, refactor, optimize.

Scope

Code Smells:

• Functions >20 lines → extract
• Duplication (3+ occurrences) → DRY
• Complexity (>3 nesting levels) → flatten
• Unused code/imports/variables → remove
• Commented code → delete
• Magic numbers → named constants
• Poor naming → clarify

Technical Debt:

• TODOs/FIXMEs → implement or delete
• Deprecated APIs → upgrade
• Outdated patterns → modernize
• Performance bottlenecks → optimize
• Memory leaks → fix
• Lint warnings → resolve

Optimization:

• Algorithm complexity → reduce
• N+1 queries → batch
• Unnecessary re-renders → memoize
• Large bundles → code split
• Unused dependencies → remove

Execution

1. Scan entire codebase systematically
2. Prioritize by impact (critical → major → minor)
3. Clean incrementally with atomic commits
4. Test after every change
5. Report what was cleaned and impact

Commit Strategy

One commit per logical cleanup:

• refactor(auth): extract validateToken function
• perf(db): batch user queries to fix N+1
• chore: remove unused imports and commented code

Exit Criteria

• No code smells remain
• All tests pass
• Lint clean
• Performance improved (measure before/after)
• Technical debt reduced measurably

Report: Lines removed, complexity reduced, performance gains.
