What to look for in a Recommendation Systems freelancer
A strong recommendation engineer connects model choices to business metrics, not just offline scores. Look for:
- Experience matching model to data: collaborative filtering, content-based, or hybrid.
- A real answer to cold-start, the problem that sinks many first attempts.
- Evaluation discipline: offline metrics plus live A/B tests that track revenue or engagement.
- Production serving know-how, so recommendations arrive in milliseconds, not seconds.
- Awareness of feedback loops and bias, so the system does not narrow over time.
Ask which metric they would optimize for your goal and how they would test it live.
