Certificates, in my opinion, are pretty demanded in todays market. They showcase your expertise on paper rather than someone saying I know Apex, I know visualforce, I am learning lightening etc.. If no certificate then you need to strongly showcase that you have worked upon the type of projects which clearly demonstrates your programming skills and abilities. I am assuming you are taking developer track since you asked about Platform Developer-1 credential. If you can conquor programming interviews then certificates may not be your primary focus. Certificates do help getting your resume closer to hiring manager though. Hope this helps!
