AI-Powered Matching

The search uses advanced semantic similarity to match candidates:
  • Vector Embeddings: Job descriptions and developer profiles are converted to high-dimensional vectors
  • Semantic Search: Matches based on meaning, not just keywords
  • ML Ranking: Results ranked by relevance using machine learning models
  • Technology Detection: Identifies relevant technologies and skills automatically
  • Experience Weighting: Considers experience level and project complexity

​
Performance Notes

  • Response Time: Typically 1-3 seconds depending on search complexity
  • Relevance Scoring: Results are pre-ranked by AI similarity
  • Caching: Frequent searches are cached for improved performance
  • Pagination: Use size parameter to control result count vs. performance
  • Filtering: Country/segment filters applied before expensive AI operations
