About Farel

Senior C++ Developer with over 9 years of experience, specializing in optimization and high-performance critical systems.

I tackle complex problems combining algorithms, performance, and business needs, particularly in the field of airline Revenue Management (Air France-KLM).

I have developed and optimized demand forecasting and revenue optimization engines based on mathematical models (LP/ILP with Gurobi), handling large volumes of data (HDFS, Avro, BigQuery).

My expertise covers:
  • High-performance C++17 development
  • Mathematical optimization (Gurobi, operations research)
  • Data engineering & cloud (GCP, BigQuery, PySpark)
  • Distributed systems and large-scale data processing
I am accustomed to agile environments (Scrum, SAFe) and critical contexts where robustness, performance, and scalability are essential.
