Let me save the updated images and replace the existing ones.

I can see the existing images are from a previous upload. The user is providing new source URLs for the same certificates. Let me overwrite them with the updated images.

Both certificate images have been updated with the latest versions you provided. The Great Learning "Artificial Intelligence with Python" certificate and the Saylor Academy "CS107: C++ Programming" certificate are now saved and will display your exact screenshots in the certificates section.

Three Coursera course certificates from University of California, Irvine, all awarded to Jaya Vital Paricherla:

1. Interfacing with the Raspberry Pi - May 7, 2023, signed by Ian Harris, Professor, Dept. of Computer Science
2. The Arduino Platform and C Programming - Apr 17, 2023, same instructor
3. Introduction to the Internet of Things and Embedded Systems - Apr 16, 2023, same instructor

Let me save the images and add them to the certificates section.

Now let me read the current certificates section to find where to add the new cards:

Now I can see the end of the certificates grid at line 813 (</div>). I'll add the three new Coursera certificate cards right before the closing </div> of the grid:

The certificates section now displays all six certificates in a 3-column grid: the BIOINNOVATE 2025 conference certificate, Saylor Academy C++ Programming, Great Learning AI with Python, and the three new Coursera certificates from UC Irvine -- Interfacing with the Raspberry Pi (May 2023), The Arduino Platform and C Programming (Apr 2023), and Introduction to IoT and Embedded Systems (Apr 2023). Each card shows your actual certificate screenshot with a title, provider, tags, and issue date below.
