I think Monetag might be a good solution for you. They accept any traffic except incentivized. They offer Push, In-Page Push, Popunder, Interstitial, Vignette and Smartlink.
Personally I would recommend In-page Push and Vignette for your website because are the less disturbing ones in my opinion. However they might be a bit annoying because they always are in light mode which doesn't fit well for your darkmode website, I guess. But maybe the support can change them to darkmode.
And to talk about the money you can earn: Monetag is a mostly CPA based business even though they pay on CPM/CPC basis. This means the better your traffic converts the better paying ads are delivered. You can cash out from just $5 via Paypal (other options available). Your money will be on hold for one month before it gets into your payable balance. This payable balance will be paid out once per month then.
(Hold period and payments per month may vary on the Priority Level you reach, I'm talking about the lowest Level)

While writing about Monetag other options came to my mind as well.
Did you think about using Carbon Ads already? This is a developer-themed, privacy friendly native ad network.
I never used Carbon before but saw them on various dev-related websites. The URL is
https://www.carbonads.net
HBagency might also be a good option. They offer refreshing ads with almost fixed $0.5-$0.6 CPM. ->
https://hbagency.it (easy to get approved, payout from 70€ via Bank)
Other headerbidding networks might be something for you as well. You can try
https://revbid.net for example. This is a Network of a friend of mine and if the Demand Partners approve you he can also offer refreshing ads at good rates. Another one, which is also featured here on BMF, is Adsvictory (Adsvictory requires at least 100k Pageviews per month).
Overall it would be good to get a bit more text to your site to get approved by better networks. It might be worth writing some articles about programming-related topics as well.
Even when delivering ads Premium Ad Networks like Hbagency, Revbid, Adsense or Adsvictory scan for keywords in the texts on your website. So the more text you write the better the delivered ads will be which results in higher CTR and higher earnings.
