Hi @sanjay-kv — thank you for looking at this.

I closed/replaced this PR because it had a few mistakes:

1. It targeted gh-pages instead of main (profile entries live on main).
2. It only added screenshots/alihamzaio.png and did not update .all-contributorsrc, which is required for profiles to load.

I've opened a corrected PR against main that updates both .all-contributorsrc and the screenshot:

#1490

Could you please review/merge #1490 when you have a moment? Related issue: #1487. Thank you!
