Searching for another word for strengthen on a resume usually means one thing: the word feels flat, and you want something a recruiter will remember. 'Strengthened' is vague. Strengthened what, and by how much? The best replacement says what changed: you improved a process, grew a relationship, reinforced a standard, or raised a metric. Pick a verb that fits the object, then add the number.
Match the verb to what you improved: a relationship (deepened, built), a process (improved, refined), a result (raised, boosted), or a system (reinforced, fortified).
