It's helpful to list skills at the bottom of your resume for HR departments doing basic pattern matching. However to paint a clearer picture I would:

1. Write relevant bullet points that show what value you provided for your previous company and BOLD languages along the way.

E.g.

- Architected a product that does $X revenue with Y languages

- Stabilized systems of X which allowed throughput of Y% more connections with Z language/framework

2. Include a summary/objective in your LinkedIn/Resume. E.g. I'm an all-around developer that isn't afraid of X, Y, Z
