Client Testimonials
J’ai travaillé plusieurs années avec Long et souvent directement avec lui. J’ai toujours apprécié sa technicité et sa volonté de trouver les meilleures solutions pour les cas d’usage demandés par nos clients. Un collègue technique et agréable avec qui travailler.

Directeur Général (LOAMICS et ENERGISME)
Long a travaillé pour nous dans un projet de conversion de programmes SAS en R. Ces interventions ont permis d’alléger et d’harmoniser le code et de le rendre plus lisible. Il travaille efficacement en proposant des transcriptions efficientes et des documentations détaillées. Je le recommande pour la clarté et l’efficacité de son travail.
