I have experience in AWS for 3 years on all most all bigdata services(Redshift, DataPipeline, Lambda, Glue, SNS, SQS, EMR). I have extensive knowledge in writing lambda functions in python. I have worked for US top retail chain, where we implemented first of its kind solutions using amazon web services for better revenue generation, which helped them to generate revenue of 6 M in few months. I also have two AWS colleagues working collectively on projects
