Professional profile
Technical sales experience from inquiry review through shipment preparation
Sean combines customer-facing sales work with practical specification review. His responsibilities cover the decisions that determine whether a greenhouse film quotation is usable: material route, finished dimensions, thickness and tolerance, UV stabilization, condensation-control functions, installation conditions, roll handling, packing and quality documents.
His work does not end when a price is issued. He participates in translating buyer requirements into a written specification, coordinating order details with production, reviewing agreed quality points and confirming packing or shipment information before delivery.
