The name Lamech in Hebrew letters is למך. 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.
למך
In short
Your name in Hebrew letters is למך. A Tanakh name: the name of two antediluvian patriarchs (first in Genesis 4:18; 11 mentions in the Tanakh). Adding up the numbers of its letters gives 90 — the same as the Torah word מן, “from”. That number points to Torah page 90 of 354 — in the portion Vayechi. What that portion is about: Jacob blesses Ephraim and Manasseh and all his sons; Jacob's death and burial in Hebron; Joseph's death. The verse that begins with the first letter of your name and ends with the last is Genesis 12:19. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Lamech” — this exact spelling is what was calculated: למך. 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 למך gives 90.

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) — 570. A Torah word with the same number is עשר — “ten” (Genesis 5:8).
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) — 36. A Torah word with the same number is אלה — “these” (Genesis 2:4).
Cumulative: a letter plus all letters before it (mispar kidmi) — 325. A Torah word with the same number is נערה — “girl, young woman” (Genesis 24:14).
Squares of the letter values (mispar perati) — 2900.
Building: the sum grows with each letter (mispar bone’eh) — 190. A Torah word with the same number is כנען — “Canaan, son of Ham” (Genesis 9:18).
The letters that come out are כיל — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 60. A Torah word with the same number is ילך — “he will go” (Genesis 3:14).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 254. A Torah word with the same number is חמור — “donkey” (Genesis 12:16).
The number 90 appears in the classical books 36 times across 19 works. The earliest mention is בעל הטורים על התורה (~1300).

The name למך appears in the Torah as a word 9 times. The first time is Genesis 4:18. 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 למך these are ל and כ. The Pentateuch has 20 such verses. The first of them is Genesis 12:19:
למה אמרת אחתי הוא ואקח אתה לי לאשה ועתה הנה אשתך קח ולך
This is from the portion Lech Lecha. What it is about: “Go forth”: Abraham leaves Haran; the promise of land and offspring; the covenant between the pieces; circumcision.
