Created expanded table structure , because more logical is to add language details in external table + company and education data are more usefull if they have start end dates and companies listed. It makes MVP bit longer to build , but might reduce Tehnical Dept... might.
Added SQL file database/sql/database.sql and laravel migration files database/migration
This is actually too popular task (I suggest to change it) - for a last 3 years I have done it 3 times already . It even has already CheatSheet for popular languages in rosettacode.
Added PHP file in public/foobar.php
public/worktime.php - Class for exec and execution included in one file. No UnitTests ( but you did not ask too...). It is not suitable (not testet , but I know issues) for people working over 24 hours
