Agent Profile for AgentPress Pro

[Angelo]

I have created an autor.php file for author profile, I use AgentPress Pro, the file shows the author-box, also shows only the author's listings (That is the idea, I don’t want to show the author posts)
I would like to know if the code is correct, or if there is any way to improve it.
I don`t know much about code, everything I do is looking for tutorials and experimenting, so I would like someone to value the code

<?php get_header(); 
 
if(isset($_GET['author_name'])) : 
$curauth = get_userdatabylogin($author_name);
else :
$curauth = get_userdata(intval($author));
endif;?>
<section class="public-profile">
<div class="author-box">
 <div class="avatar"><?php echo get_avatar( $curauth->user_email , '120'); ?></div>
    <h3 class="author-box-title"><?php echo $curauth->nickname; ?>:</h3>
    <p class="author-box-content"><?php echo $curauth->user_description; ?><br />
    <a href="<?php echo $curauth->user_url; ?>"><?php echo $curauth->user_url; ?></a></p>
   </div></section>

<!-- Show just listings from the author -->
<?php $args = array(
    'post_type' => 'listing' ,
    'author' => get_queried_object_id(), // this will be the author ID on the author page
    'showposts' => 10
);
$custom_posts = new WP_Query( $args ); ?>
<?php if ( $custom_posts->have_posts() ): ?>
    <div class="author-by"><h5>Proximos eventos de: <?php echo $curauth->nickname; ?></h5>
<span class="dashicons dashicons-arrow-down-alt2"></span></div>
   <div class="flex-container"> <?php while ( $custom_posts->have_posts() ) : $custom_posts->the_post(); ?>
<div class="author-listing-title">
    <a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link: <?php the_title(); ?>">
<?php the_title(); ?></a>

</div>
    <?php endwhile; ?>
<?php else: ?>
    <p><?php _e('User has no Listings'); ?></p>
<?php endif; ?></div>
<!--LOOP ENDS-->

<?php get_footer(); ?>
