The name Senaida in Hebrew letters is סנאיידה. 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.
סנאיידה
In short
Your name in Hebrew letters is סנאיידה. Adding up the numbers of its letters gives 140 — the same as the Torah word מעל, “above”. That number points to Torah page 140 of 354 — in the portion Tetzaveh. What that portion is about: “Command”: oil for the lamp; the priestly garments — the ephod, the breastplate with twelve stones; the consecration of the priests. The verse that begins with the first letter of your name and ends with the last is Numbers 14:19. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Senaida” — this exact spelling is what was calculated: סנאיידה. 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 סנאיידה gives 140.
140
The number 140 is the Torah word מעל — «above» (Genesis 6:16).
And they shall bind the breastplate by the rings thereof unto the rings of the ephod with a thread of blue, that it may be upon the skilfully woven band of the ephod, and that the breastplate be not loosed from the ephod.
This is from the portion Tetzaveh. What it is about: “Command”: oil for the lamp; the priestly garments — the ephod, the breastplate with twelve stones; the consecration of the priests.
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) — 140. A Torah word with the same number is מעל — “above” (Genesis 6:16).
Reduced, each letter to one digit (mispar katan) — 23.
Cumulative: a letter plus all letters before it (mispar kidmi) — 586. A Torah word with the same number is שופר — “ram's horn, shofar” (Exodus 19:16).
Squares of the letter values (mispar perati) — 6342.
Building: the sum grows with each letter (mispar bone’eh) — 808. A Torah word with the same number is תחת — “under, beneath” (Genesis 1:7).
The letters that come out are חטתממקצ — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 687. A Torah word with the same number is מזמרת — “of the choice produce of” (Genesis 43:11).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 817. A Torah word with the same number is אתתיו — “his signs” (Deuteronomy 11:3).
The number 140 appears in the classical books 16 times across 7 works. The earliest mention is בעל הטורים על התורה (~1300).

The number of the day, every morning
Every date has a number too. Once a year it will match the number of your name — 140. The channel posts one number a day, one verse and the Torah page it lands on. Nothing after it, no mailing list.

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 סנאיידה 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 סנאיידה these are ס and ה. The Pentateuch has exactly one such verse — Numbers 14:19:
סלח נא לעון העם הזה כגדל חסדך וכאשר נשאתה לעם הזה ממצרים ועד הנה
This is from the portion Shlach. What it is about: The twelve spies; forty years for forty days; challah and tzitzit.
Any name written in Hebrew letters is a number: סנאיידה = 140. And every date has a number of its own. There is a day in the year when the two coincide.
«And they shall bind the breastplate by the rings thereof unto the rings of the ephod with a thread of blue, that it may be upon the skilfully woven band of the ephod, and that the breastplate be not loosed from the ephod.»
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.
