The name Rosaura in Hebrew letters is רוסאורה. 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.
רוסאורה
In short
Your name in Hebrew letters is רוסאורה. The name comes from the Latin words “rosa aurea”, which mean “golden rose”. Rosaura is a heroine of Calderón's play “Life Is a Dream”, written in 1635. This form of the name is used in Spain and Latin America. In Hebrew it is written by sound. Adding up the numbers of its letters gives 478 — the same as the Torah word חצרעינן, “Hazar-enan”. That number points to Torah page 124 of 354 — in the portion Yitro. What that portion is about: Jethro's counsel on judges; standing at Sinai; the Ten Utterances; “you shall not make yourself an idol”. The verse that begins with the first letter of your name and ends with the last is Exodus 1:2. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Rosaura” — this exact spelling is what was calculated: רוסאורה. 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 רוסאורה gives 478.
478
The number 478 is the Torah word חצרעינן — «Hazar-enan» (Numbers 34:9).
and ye shall be unto Me a kingdom of priests, and a holy nation. These are the words which thou shalt speak unto the children of Israel.'
This is from the portion Yitro. What it is about: Jethro's counsel on judges; standing at Sinai; the Ten Utterances; “you shall not make yourself an idol”.
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) — 478. A Torah word with the same number is חצרעינן — “Hazar-enan” (Numbers 34:9).
Reduced, each letter to one digit (mispar katan) — 28. A Torah word with the same number is כח — “strength” (Genesis 4:12).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 73. A Torah word with the same number is גמל — “camel” (Genesis 12:16).
Cumulative: a letter plus all letters before it (mispar kidmi) — 1903.
Squares of the letter values (mispar perati) — 83698.
Building: the sum grows with each letter (mispar bone’eh) — 2163.
The letters that come out are גפחתפגצ — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 664. A Torah word with the same number is במרכבת — “in the chariot of” (Genesis 41:43).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 1281.
The number 478 appears in the classical books 5 times across 4 works. The earliest mention is ילקוט שמעוני (~1260).

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 רוסאורה 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 רוסאורה these are ר and ה. The Pentateuch has 10 such verses. The first of them is Exodus 1:2:
ראובן שמעון לוי ויהודה
This is from the portion Shemot. What it is about: Slavery in Egypt; Moses in the basket on the Nile; the burning bush and the Name; the first audience with Pharaoh.
Any name written in Hebrew letters is a number: רוסאורה = 478. And every date has a number of its own. There is a day in the year when the two coincide.
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.
