Greetings,
How are you!
After going through your requirements, I am interested in Part A and I would like to share that I can fulfill your requirement. Below is brief description about my self.
I am having 8+ years of working experience in Technologies like Python, Java and other big data technologies like Spark, Hive and Hadoop. Also developed many spark applications in AWS by implementing AWS Services like Lambda, Step Functions, SNS, Glue, Redshift. Also I have created Airflow DAGs by creating custom hooks and operators to connect to s3, Lambda, EMR, and SSM(System Manager) and deployed these schedulers in our prod implementation.
With above experience and skillset, I strongly feel that you will be highly satisfied with the quality of work and on time delivery.
You can reach out to me any time. Looking forward to hear from you!
Thanks.
