Future as terminated employee

Question

Hi, my question here is regarding my future as terminated employee. I live in Gujarat. I completed my MCA in 2012 and I started my job in Android in Gujarat. I was doing freelancing jobs as well. But due to contract with company, when they get to know about my other source of income from freelance, they terminated me with violence of contract. At that time my experience was around 1.5 year. They just provided my termination letter and nothing else. But then after I got job in same field and since last 3 years I am doing my job in a small company. They don't ask me for providing experience certificate. I am intermediate Android developer and currently having position of Sr. Software Engineer. Here my concern is what is my future? Am I eligible to get job in MNC (CMM level) or bigger companies? What are my chances of getting job in Abroad countries like Australia, Canada etc. Is my career ruined due to this? Please guide me. I am very much upset and I lost my self confidence as well. Regards Raj.
