convert validation rule to trigger

Hi All,
I am very new to development and aI have to change one validation rule on Opportunity into trigger using custom settings.
For example:Validation rule on an opportunity has some profiles, some roles and stage 
something like below-
AND(
ISPICKVAL(StageName ,"Pending"), 
ISPICKVAL(StageName ,"Closed") , 
NOT($Permission.Bypass_Rule_Exclusion), 
$Profile.Name <> " Contractor", 
$UserRole.Name <> "Analyst")

and I need to change this validation rule into trigger.
I can move this hardcoded values to custom settings,but I am not sure how to write a trigger .
Could someone please help me.

Hi Taha,

Asssuming you want the validation to fire on both Update and Insert you can use the below code. I have modified the code to meet your requirements. Please select this as best answer if the solution works for you. 
trigger Opptrigger on Opportunity (after insert, after update) {

List<User> cUser = [SELECT UserRole.Name,Profile.Name from User];
List<PermissionSet> PermList = [SELECT Label FROM PermissionSet];
 Set<Id> setofOppId = new Set<Id>();
        
for(Opportunity objOpp: trigger.new){
               
 setofOppId.add(objOpp.Id);
       
 }

List<Opportunity> OppList = [Select Stagename from Opportunity where id IN :setofOppId]

for(Opportunity Data : OppList){
 for(User Udata : cUser){
for(PermissionSet Pdata : PermList){
                   if((StageName == 'Pending' || StageName == 'Closed') && Udata. UserRole.Name != 'Contractor' && Udata.Profile.Name != 'Analyst'  && PermList.Label != 'Bypass Rule Exclusion' )
{
                      Data.addError('Add your error message here');
}
}
}
}
}
