Walaikum Assalam! Here’s a simple and professional introduction of yourself and your job in English:

Introduction:
My name is Zakir Rehman. I am an online Quran teacher.
I have experience teaching the Holy Quran with proper Tajweed (pronunciation rules) to students of all ages. I teach Quran reading, memorization (Hifz), and basic Islamic teachings. My goal is to help students understand and love the Quran through easy and effective lessons. I conduct classes online, so students can learn from the comfort of their home at flexible timings.
