Myself nor @GitCitadel are probably not established enough for you to get credit here "Reputable Company" but myself and GitCitadel are working on C/C++ projects on nostr if you are still interested in contributing code. My project noscrypt is a strict C cryptography library. I don't accept PR's on github only patches, I have a guide for it on my website

A nostr specific cryptography library written in C - VnUgE/noscrypt

Open issues are found https://www.vaughnnugent.com/resources/software/modules/noscrypt-issues?state=Defined It needs help with hardware support as well, well really anything in the hardware department :) @GitCitadel Is working on a C++ nostr development kit called Aedile, among another dozen projects (feel free to ask)

GitHub - ShadowySupercode/aedile-ndk: C++ System Development Kit for Nostr

C++ System Development Kit for Nostr. Contribute to ShadowySupercode/aedile-ndk development by creating an account on GitHub.

We can probably accept GH prs otherwise we use our own managed git server In either case, if your commits include your github email address your contributions should be mirrored to github if you make any. Finally, my nostr DMs don't work (see my other project nvault as to why)
