ABOUT ME

WHO AM I?

Hello! I am a full-stack developer.

I have 10+ years of experience in full life cycle of software development including requirement definition, proof of concept, design, implementation, testing, deployment and maintenance.

In my current job, I create prototypes and build solutions with cutting edge technologies such as Machine Learning, Blockchain, and Nature Language Processing (NLP).

I have experience in leading and working with offshore teams to develop new products and maintain old products. I also have experience in building infrastructure and processes for a startup company.
