C’est moi !

Salut !

Je m’appelle Mandeep.

You could also transliterate your name to "Mandip", which would be more natural considering French phonology. <ee> stands for a long /i/ pretty much only in English

J’ai vingt -huit ans.

Hyphen between parts of a number

Je suis en train d’'apprendres la langue française.

The "être en train de" structure would've looked a bit odd here, because learning is a long process, you didn't stop learning French just after uttering this sentence

Je veuxoudrais que quelqu'un m'aider moi dans à apprendre cette langue, alors je develope dans ma vie avec ma career pour progresser dans ma vie et dans ma carrière (professionanelle).

"je veux" is pretty rude, it sounds like you're ordering people around. The conditional mood is used for making polite requests

Here you'd literally say "I want that someone helps me", with "aider" in the subjunctive tense after "vouloir que" => je voudrais que quelqu'un m'aide

Non tonic object pronouns are => me, te, le/la, nous, vous, les
They come before the infinitive and "me" is elided to "m'" here since the following word starts with a vowel => M'aide

aider quelqu'un À faire quelque chose

progresser = to progress
In a pinch you would say "je ME développe" (reflexive) but it would sound highly unnatural here

Je attente pour votre 'espère que vous m'aider.ez

"attendre" is directly transitive (attendre quelque chose)
Here again it would sound.. demanding. "J'espère que vous m'aiderez", lit. "I hope you'll help me" is far more natural and polite

Merci !
