In general, you can translate "I X, therefore I Y" into Latin as X ergo Y (with
appropriate conjugation of the verbs).
Even more so if you want a reference to Renatus Cartesius.
The only remaining question is to find appropriate translations for the verbs.
As discussed in the previous question, "I am" is well translated by sum and "I make" by facio.
Thus sum ergo facio is a good translation in the specific case you ask about.
You can easily construct similar phrases with other verbs.
Many dictionaries list verbs with just the right form (present active indicative first person singular), so you only need to find the verbs that fit your needs.
If you want to explore different options, I suggest you start by entering an English verb of your choice to some online Latin dictionary and then look at the translations from Latin to English from each candidate on your list of Latin verbs.
