Hi Kel, supply chain is a very broad industry, comprising different aspects. They range from 3PL (e.g. KNN, DB Schenker) , express (e.g. DHL, Fedex), last mile (e.g. Ninjavan), to transporters.
On the shipper side, there are also operations/supply chain departments.
From a functional perspective, based on your description, your strengths are more inclined towards operations and operations-support roles.
For operations, you can try exploring warehouse executive/manager kind of roles.
For operations-support, you can check out roles such as industrial engineering, implementation, costing/tender roles.
