Scientific poster by an industry researcher: What do I put as contact information?
If your work was supported by your employer, then you should use your company address to acknowledge the affiliation. If it's work done in your spare time that is not sponsored by your employer, use your personal details.

Don't bother with the phone number – in academia, it's generally considered bad etiquette to call someone unexpectedly (unless it's an emergency).

Use whichever email address you wish – if it's a "professional" address like firstname.lastname@domain.com, it doesn't matter. You might lose access to your email address if you change employer, so it's also important that you use an address you'll have access to for the foreseeable future.
