The name Joana in Hebrew letters is חואנה. Below: how its number adds up, which page of the Torah it falls on and what verse stands there. Everything is computed, nothing is guessed.
חואנה
In short
Your name in Hebrew letters is חואנה. The name comes from Hebrew: from יוחנן, Johanan; in the Tanakh, name of nine Israelites (2 Kings 25:23). Adding up the numbers of its letters gives 70 — the same as the Torah word כן, “so, thus”. That number points to Torah page 70 of 354 — in the portion Vayeshev. What that portion is about: Joseph's dreams and his sale by his brothers; Judah and Tamar; Joseph in Potiphar's house and in prison; the dreams of the butler and the baker. The verse that begins with the first letter of your name and ends with the last is Genesis 25:15. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Joana” — this exact spelling is what was calculated: חואנה. A name from the Tanakh — its Tanakh spelling is used. If your name is spelled differently, correct the Hebrew spelling and the report is recomputed.
Adding up the letters of the name חואנה gives 70.

Other ways of counting
The tradition counts the same name in several ways. The main one is above: each letter is its number. The other eight are old and checkable too; each gives its own number, and many of them have a Torah word with the same number.
Final letters as 500–900 (mispar gadol) — 70. A Torah word with the same number is כן — “so, thus” (Genesis 1:7).
Reduced, each letter to one digit (mispar katan) — 25. A Torah word with the same number is כה — “thus, so” (Genesis 15:5).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 34. A Torah word with the same number is לבב — “heart” (Genesis 20:5).
Cumulative: a letter plus all letters before it (mispar kidmi) — 268. A Torah word with the same number is חסר — “to lack, decrease” (Genesis 8:3).
Squares of the letter values (mispar perati) — 2626.
Building: the sum grows with each letter (mispar bone’eh) — 172. A Torah word with the same number is בקע — “to split” (Genesis 7:11).
The letters that come out are ספתטצ — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 639. A Torah word with the same number is והתברכו — “and they shall be blessed” (Genesis 22:18).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 653. A Torah word with the same number is ארנבת — “hare” (Leviticus 11:6).
The number 70 appears in the classical books 90 times across 44 works. The earliest mention is בעל הטורים על התורה (~1300).

The number of the day, every morning

For an engraving, a sign or a tattoo, show the spelling to someone who reads Hebrew: transliterating a name is a choice, not the only option.
The name חואנה does not stand as a word in the Pentateuch — as with most names, including many Tanakh names from the later books.
The verse of your name
There is a custom: at the end of the prayer one says a Torah verse that begins with the first letter of one's name and ends with its last. For חואנה these are ח and ה. The Pentateuch has 3 such verses. The first of them is Genesis 25:15:
חדד ותימא יטור נפיש וקדמה
This is from the portion Chayei Sarah. What it is about: Sarah's death and the purchase of the cave of Machpelah; the servant seeks a wife for Isaac; Rebecca at the well; Abraham's death.
Each Hebrew letter has a number; a word's number is their sum (alef 1 … tav 400). The page is the remainder modulo 354: the Torah divided into 354 pages of 861 letters, as the lunar year has 354 days. Everything can be checked by hand.
