What adverb should I use in this sentence?

Question

I am trying to translate I come home not long after you arrive in Esperanto. Google Translate gives me the following sentence.

Mi venas hejmen post nelonge vi alvenas.

Should not baldaŭ be used instead of post nelonge, since its meaning is post mallonga tempo (after not much time)?

If I change the sentence, Google Translate uses baldaŭ.

I come home soon after you arrive. (Mi venas hejmen baldaŭ post vi alvenas.)

To me, post seems already implicit in baldaŭ, and I would rather translate the sentence with:

Mi venas hejmen baldaŭ vi alvenas.

What adverb should I use for an action that happens soon after another action?

Answer 1

You might consider tuj ("straightaway"). However, one problem with using baldaŭ or tuj here is that it is unclear where the short time interval starts: now, or at the time of the other person's arrival. I'd suggest:

Mi revenas hejmen nelonge post via alveno.

Mi revenas hejmen nelonge post kiam vi alvenas.

Note that antaŭ and post become antaŭ ol and post kiam when followed by a clause.

To make it clear that you are describing what usually happens, not a single event, you can insert kutime or ĝenerale after mi.

Answer 2

I'd say

Mi venos hejmon baldaŭ post kiam vi alvenis.
