⚡ Bolt: Optimize matching algorithms by consolidating array methods#319KxlSys wants to merge 1 commit into
Conversation
Refactored `calculateMatches` and `calculateProjectMatches` to replace chained `.filter().map().filter()` array operations with single `for` loops. This prevents redundant O(n) passes over the data and avoids allocating temporary intermediate arrays for better performance during data aggregation.

68-70: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick winConsider making tech matching case-insensitive.
Unlike
calculateProjectMatches, which normalizes techs to lowercase, this matching logic requires an exact case match. If candidates use different casing (e.g., "React" vs "react"), they might miss out on points. Consider normalizingcurrentUserTechsSetandcandidate.tech_stackto lowercase before comparing.💡 Proposed case-insensitive matching
Update the set initialization (around line 48) to lowercase the user's stack:
const currentUserTechsSet = new Set(currentUser.tech_stack.map(t => t.toLowerCase()));And update the filter loop to lowercase the candidate's techs:
- const commonTechs = candidate.tech_stack.filter((t) => - currentUserTechsSet.has(t) - ); + const commonTechs = candidate.tech_stack.filter((t) => + currentUserTechsSet.has(t.toLowerCase()) + );🤖 Prompt for AI Agents

61-62: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick winHoist loop invariants to reduce redundant work and allocations.
Since this PR focuses on reducing allocations and passes over data, several constant expressions and objects that do not depend on the loop iteration should be hoisted outside the loops to maximize performance.

💡 What:
Consolidated array mapping and filtering in
src/lib/matching.tsinto a single loop forcalculateMatchesandcalculateProjectMatches.🎯 Why:
Chaining multiple array methods (
.filter().map().filter()) on large arrays (like candidate profiles or projects) creates unnecessary intermediate arrays and forces the CPU to iterate over the dataset multiple times.📊 Impact:
Improves CPU cache locality and reduces garbage collection overhead, particularly when datasets scale to thousands of users or projects, by converting multiple O(N) passes to a single O(N) pass.
🔬 Measurement:
Run
pnpm run testto verify that all matching algorithms still produce identical sorted scores and identical output arrays. The overall processing time per query is measurably reduced in V8 profiling.PR created automatically by Jules for task 4431554792924675838 started by @KxlSys
