His role is based on risk anticipation, constructability and coordination. He secures critical stages (galvanisation, liquid evacuation, resistance to demanding environments) and contributes to projects related to hydrogen, ammonia and new 3D models. 

‘In this job, technical skills are not enough: you have to listen, anticipate and know how to say no when safety or quality are not guaranteed,’ he emphasises. 

His career in France, Spain, Australia and Bangladesh illustrates the opportunities offered by this profession. Joining his teams means working on demanding projects where rigour, communication and safety are key.
