2 years ago I got this current job as a software developer in a very reputable company. I've been performing very well since the day I joined ,and last year i scored 86.5 out of 100 in an performance review. Also I am now considered as one of the best programmers.
Years ago, I and two other friends started a start-up company and I was the CTO, exactly a year later I resigned due to some business level conflicts we couldn't resolve. They never gave me an experience certificate and now the company is no longer in the software developing business, they do digital marketing things.
After resignation, I got a job at an outsourcing company by cracking the interview with a higher score.
A year later I resigned and got this current job, again scoring highest points at the interview series including the technical interview.
Since I could not get an experience certificate from my first company, I created one and gave it to my current company and the previous one. Since I was the CTO at the first company and I did lots of hard work I thought I deserved it.
The HR department relocated to new office premises and they misplaced documents of a few employees during the process. They never asked me to resubmit them until now.
There is a promotion waiting and HR asked me to submit those documents to complete the employee profile so they can proceed with the promotion thing (they consider total years of experience for this).
During the resubmission of docs, will I get caught with the fake experience certificate?
What can I do to correct this error?
EDIT i do have company registration with my name on it as a director
