ABOUT THE CLIENT

Jobmaker, active since 2015, has established itself as an innovative digital platform in professional coaching. A trusted partner of prestigious companies like EDF, Enedis, and Orange, Jobmaker supports employees in their career development through personalized programs.

TECHNICAL CHALLENGE

The major challenge was to transform the writing portion of coaching, traditionally time-consuming, into a smooth and efficient process. Our mission: develop an AI solution capable of maintaining quality while eliminating friction in the user journey.

AI Model Limitations

  • Resource management for Mistral-7B

  • Response time optimization

  • Balance between performance and infrastructure cost

GDPR compliance, security and AI ACT

  • User data anonymization

  • Fine-tuning process security

  • Protection of sensitive information

Training Data Quality

  • Building a representative dataset

  • Data cleaning and validation

  • Intensive testing before deployment

SOLUTION

Our solution is built around three major technological pillars:

Sophisticated Data Preparation The quality of an AI model relies on its training data. Our team developed a rigorous methodology to build a dataset of 1200 examples. The use of embeddings helped validate data relevance by measuring similarity between inputs and user responses, thus ensuring the quality of the training corpus.

Advanced Fine-tuning The core of our solution relies on Mistral-7B, a cutting-edge language model. Our fine-tuning process via Hugging Face was optimized for Jobmaker's specifics:

  • Adaptation to professional writing standards

  • Adherence to editorial guidelines

  • Preservation of Jobmaker's DNA in reformulations

Secure Deployment The technical infrastructure was deployed on RunPod.io in France, ensuring:

  • GDPR compliance

  • High availability

  • Optimal performance

METHODOLOGY

The project ran for two months, led by an expert team:

  • 1 AI Engineer

  • 1 Product Manager

  • 1 Developer

Our development process was structured in three key phases:

Phase 1: Data Preparation In-depth analysis and anonymization of historical data, with particular attention to dataset quality and representativeness.

Phase 2: Fine-tuning and Development Iterative optimization of the Mistral-7B model, with testing cycles and continuous improvement based on user feedback.

Phase 3: Deployment and Optimization Progressive production rollout with performance monitoring and real-time adjustments.

RESULTS

The solution has radically transformed the coaching experience:

Technical Performance

  • Reduction in reformulation time from 15 minutes to instant response

  • 90% user satisfaction rate
