Developing & enhancing the User Interface using Angular JS framework & Node JS as backend service built on AWS infrastructure. Developing build & release pipelines for better & optimized code delivery. Leading team of QAs, developed & implemented TOSCA codeless automation scripting to test the application from scratch. Built full single click QA & test automation & reporting to call out any application flaws through TOSCA, leveraging GitLab pipelines. Recursively developing test scripts for new features getting added. Provisioning & developing the backend services in AWS to support End User Interface API calls & integrated with Databases like Dynamo DB & Neptune DB. Architecting, mapping & documenting the backend services as per business logic through Terraform. Automated the underlying infrastructure to withstand failures & implemented fault tolerance mechanism so that in times of failure, no obstruction arises & network traffic should route to Disaster recovery site automatically at scale. Building up the User Interface according to the wireframes in Ember JS framework to interact with backend services using API Gateway, Lambda functions to process information & helping the end user to further process their tasks at ease by using a suite of products. Utilizing Agile/Scrum methodologies to enhance work speed of product delivery. Implemented & supporting extensive monitoring of backend environment through CloudWatch logging & Eventbridge mechanisms & also incorporated Datadog, Grafana & integrating with Prometheus DB. Developed & implemented custom auditing within the application using Lambda function & CloudWatch logs. Neptune DB to store the logs & can be checked through application UI. Providing the support for application incidents & requests from the business users & resolving with stipulated SLA. Integrated multiple AWS services like AWS Connect, Kinesis, Dynamo DB with custom made application connect to serve internal routing flows similar to AWS Connect with the application as per business scope & guidelines. Worked on creating Gremlin queries to serve extraction or give an oriented view to the data whatever way the process requires in terms of Neptune DB. Built several POCs leveraging container led technology & deployed various SPAs on docker using kubernetes orchestration. Attending daily scrum & at times retrospective, planning, refinement & review meeting with client stakeholders & with fellow developers. Integrated application with Azure AD authentication to serve SSO purpose. Deploying & pushing application code in Lambda & S3 bucket through GitLab Pipelines & loading the dependencies from JFrog. Running SYNK vulnerability scans as part of every production release & making a practice every time for smooth release. Did several PoCs on Data Engineering & Analytics such as developed various Pig/Hive on Tez queries to analyse & drill data further to achieve desired results. Developed PySpark scripts to load data in Hadoop cluster & converting to RDDs, Dataframes involving map & reduce functions breaking data further. Importing/Exporting data to/from Hadoop cluster to/from Databases. Did use case involving HBase/Pig integration. Ingesting data to CassandraDB through PySpark. Integrated multiple DBs such as MySQL, CassandraDB using Apache Drill & queried data grouping all DBs at once. Created Oozie workflow leveraging Sqoop & Hive. Leveraged Flume & published logs & stored data inside HDFS. Performing various operations, created materialized views on datasets leveraging GCP , scheduling it at certain timeframes & integrating it to run after processing is completed through ETL pipelines created through Apache Beam. Did use cases involving clustering & partitioning in BigQuery. Created reports in Apache Datastudio. Leveraged Python libraries such as Scikit-learn, Tensorflow in AI/ML production lifecycle to visualize various models.
