出たて uses the suffix ~たて ('freshly, just done') attached to a verb stem, parallel to ~たばかり but more colloquial and tactile — typically used for fresh food, newly minted graduates, or anything in its first-bloom state. 焼きたて ('fresh-baked'), 取れたて ('just-picked'), 出たて ('just out / fresh out'). The で here is the te-form of the copula だ, linking the descriptive clause to the second clause about lacking experience.
