Advanced Reinforcement Learning (RL) recommendation system developed for Shiftpartner to intelligently suggest optimal shifts to workforce members based on personalized preferences and operational requirements.
Sophisticated RL model implementing reward-based learning mechanisms to continuously improve shift recommendations, combining pre-trained models with live online learning for adaptive personalization.
Features automatic feature identification and engineering, enabling the system to discover relevant patterns in user behavior, shift characteristics, and operational constraints without manual feature specification.
Shiftpartner users faced overwhelming choices when selecting shifts, struggling to identify opportunities matching their preferences for location, timing, pay rates, and work-life balance constraints.
Static rule-based shift suggestions failed to adapt to individual preferences or learn from user behavior, resulting in irrelevant recommendations and low engagement with suggested opportunities.
Manual feature engineering for recommendation systems required extensive domain expertise and constant updates, while failing to capture complex, evolving patterns in workforce preferences and shift characteristics.
