Developer looking for marketing guru

I'm a proficient software developer (prefer backend, but I'm fullstack) but I'm not well versed in marketing. Looking for someone who knows how to market effectively, and could benefit from a technical partner.

Languages include PHP, C#, Java, Javascript; Frameworks include Laravel, Vue, React. I work remotely as a backend developer for my day job, and have a good degree of available time M-F. Let me know if questions.
