The name Demi in Hebrew letters is דמי. 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.
דמי
In short
Your name in Hebrew letters is דמי. In Hebrew letters the name is spelled like the Tanakh word “quiet” (Isaiah 38:10). This is a shared spelling, not the origin of the name. Adding up the numbers of its letters gives 54 — the same as the Torah word מטה, “staff, tribe”. That number points to Torah page 54 of 354 — in the portion Vayetzei. What that portion is about: The dream of the ladder to heaven; Jacob with Laban: Leah and Rachel; eleven sons are born; the return. The verse that begins with the first letter of your name and ends with the last is Exodus 25:2. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Demi” — this exact spelling is what was calculated: דמי. 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 דמי gives 54.
54
The number 54 is the Torah word מטה — «staff, tribe» (Genesis 38:18).
Thus I was: in the day the drought consumed me, and the frost by night; and my sleep fled from mine eyes.
This is from the portion Vayetzei. What it is about: The dream of the ladder to heaven; Jacob with Laban: Leah and Rachel; eleven sons are born; the return.
The same number, 54, is given by these Tanakh names:

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) — 54. A Torah word with the same number is מטה — “staff, tribe” (Genesis 38:18).
Reduced, each letter to one digit (mispar katan) — 9. A Torah word with the same number is בוא — “to come, enter” (Genesis 2:19).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 27. A Torah word with the same number is בכה — “to weep” (Genesis 21:16).
Cumulative: a letter plus all letters before it (mispar kidmi) — 210. A Torah word with the same number is דור — “generation” (Genesis 6:9).
Squares of the letter values (mispar perati) — 1716.
Building: the sum grows with each letter (mispar bone’eh) — 102. A Torah word with the same number is בעל — “master, owner” (Genesis 14:13).
The letters that come out are קימ — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 150. A Torah word with the same number is יסף — “to add” (Genesis 4:2).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 534. A Torah word with the same number is דלקת — “inflammation, fever” (Deuteronomy 28:22).
The number 54 appears in the classical books 3 times across 3 works. The earliest mention is מגלה עמוקות (~1637).

The number of the day, every morning
Every date has a number too. Once a year it will match the number of your name — 54. The channel posts one number a day, one verse and the Torah page it lands on. Nothing after it, no mailing list.
Hebrew is written from right to left. דמי has 3 letters: ד Dalet, מ Mem, י Yod. The first letter is Dalet, the last is Yod.
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 דמי appears in the Torah as a word 3 times. The first time is Genesis 4:10. Another 1 time it stands with prefixes — “and”, “in”, “the”.
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 דמי these are ד and י. The Pentateuch has 3 such verses. The first of them is Exodus 25:2:
דבר אל בני ישראל ויקחו לי תרומה מאת כל איש אשר ידבנו לבו תקחו את תרומתי
This is from the portion Terumah. What it is about: The offering for the Sanctuary; the Ark, the table and the lampstand; the Tabernacle and its curtains; the altar.
The name דמי has no such day. The numbers of the dates in a year cover 326 values out of 940, and 54 is not among them. Half of all names are like this — neither good nor bad, just a fact of counting.
Add a date of birth and the verse of meeting from that week's portion is added to the reading.
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.
