You shall feel over the moon after reading the good news I am about to chase you.

I keep hopping over from one job to another because of unsatisfaction. As I was not getting work related to my specialization. In addition to this, I was not getting paid satisfactorily.

However, the new organization has offered me the role of technical lead where I have to handle a team of 10 people. While doing this, I will not only enhance my knowledge by solving issues of 10 colleagues but also I will get chance to interact with customers to understand their requirements.

Besides the professional career, I would like to inform you that my engagement has been fixed on 5^th of the next month. Obviously, I will send you the separate invitation for this but this is the alarm to get prepared with your clothes for the great event.

Looking forward to listen from you soon.
