Can I ask people to upvote my submission?

No. Users should vote for a story because they personally find it intellectually interesting, not because someone has content to promote. We penalize or ban submissions, accounts, and sites that break this rule, so please don't.*

Can I ask people to comment on my submission?

No, for the same reason. It's also not in your interest: HN readers are sensitive to this and will detect it, flag it, and use unkind words like 'spam'.

Also, my recommendation is to not use "pls".

A blog post with a short technical description and a few screenshots may get more traction.
