  • AWS Data and analytics (Data warehousing/data lake)
  • Planned and Performed end to end process of data lake creation by uploading data from CSV file to S3 and used AWS Glue to extract the data from S3, do transformations and then load data back to S3 or to redshift based on the requirement and scenario. Used Athena to query the data via the AWS Glue database. Added triggers to job and workflow to run the whole flow in defined schedule periodically.
  • High Availability Architecture
  • Designed and setup a high availability Architecture of a word press website for client’s internal users and employees based on their requirement using Multi AZ and separate private and public security groups and services like Elastic Load balancer, Auto scaling group, CloudFront, EC2 instances, RDS instances and S3 buckets.
  • Hand on with other AWS services like
  • Compute (EC2, Elastic Beanstalk, Lamda), databases (RDS, DynamoDB, Redshift),networking and content delivery (VPC, cloud front, route53 DNS, API Gateway, direct connect ), analytics (Athena, kinesis, glue), security identity and compliance (IAM), Storage (S3, EFS, Snowball, storage gateway, EBS)

Project Lead

Responsibilities:

  • As a Database development lead and AWS cloud engineer, leading and mentoring a group of pl/sql developers and Confidential the same time involved in PL/SQL development, performance tuning, requirement gathering, Legacy system analysis, onsite-offshore co-ordination, development and configuration of various components. Involved in design and architecture of PL/SQL application as well. AWS cloud activities involved On Database migration (On-premise to Cloud) and High Availability Architecture design and implementation.
  • Executed POCs on Oracle CDC to captures changes in data, Oracle Messaging gateway so that the data can be transferred across the heterogeneous systems and assessment of Oracle Data Integrator and Oracle GoldenGate to decide the tools that can be used in the system architecture.
  • Worked with Data modelers to review the physical data model based on table design requirements.
  • Extraction & Preparation of weekly Reports as per business requirements using shell scripting with embedded SQL and Jobs to automate periodic maintenance tasks.
  • Build the detailed design and architecture of the project and mentored the team members to efficiently implement the rules using proposed technologies.
  • Resolved issues found during SIT, UAT and production implementation.
  • Was responsible for coordination between offshore development team, business, and technology and management groups.
  • Also been performing Oracle DB administration of Application DBs in dev environment performing maintenance and changes to various DB objects like tables, indexed, packages, procedure etc in RAC environment.
  • Gained good knowledge of system architecture built over multiple layers including Front end servers, backend servers, web logic servers along with load balancer and authentication management servers etc.
  • To summarize this specific application, raw data is extracted mostly using SQL loader and then transformations were done using ODI and data was loaded to tables.
