Developed consumer-based features and applications using Python, Django, pyramid, Flask, Web2py, HTML and other web technologies. Designed, developed and integrated a PostgreSQL database of ontological information with a proprietary Scala- based NLP pipeline. Enabled AWS Data Migration services to fetch the data from Source systems viz Oracle to copy the records which are either inserted or updated on the fly to S3 bucket. Built reusable and customizable components for the new website using React.JS and React-Routes to create a single page web application. Worked on Django REST framework as it is much faster to read data and it can be cached. REST allows more formats than SOAP and gives better support for browser clients as it supports JSON. Also, Created templates for page rendering and Django views for the business logic. Enabled to trigger Lambda Services on top of S3 bucket whenever the file drops from DMS. This Lambda would update the record count in Dynamo DB to have a count of number of files dropped in every group. Designed and developed web crawler in python using Scrappy framework and using RabbitMQ as a messaging server between the micro services. Automated Testing Framework has been built to comply with CI/CD pipeline using Nose Test and PyTest also implemented CI/CD pipeline using Jenkins, Ansible Playbooks and Ansible Tower. Created an on premise CI/CD solution using Jenkins and the Pipeline plugin which uses pipeline as code. Developed a POC using Attunity for fetching files directly from Source Oracle system to Snowflake directly, but which involved a large licensing cost and processing charges. Used Elastic Container Service and Elastic Kubernetes service as part of Jenkins Job to enable any code changes in repository get reflected to services involved. Developed Cloud Formation scripts to create DMS tasks which involves to setup several variables and connections in the Airflow console.

Hive Being the primary query engine of EMR, we’ve created external table schemas for the data that is being processed. Secured Apache Hue’s default settings by configuring Https protocol, with self-signed certificates, to make sure the data is encrypted in Transit and in Rest. Developed web page and form validation with team using Angular.JS, React.Js, Bootstrap.js, Node.js, Backbone.js, HTML5, CSS & JavaScript. Developed Apache presto and Apache drill setups in AWS EMR (Elastic Map Reduce) cluster, to combine multiple databases like Mysql and Hive. This enables to compare results like joins and inserts on various data sources controlling through single platform. Created AWS RDS (Relational database services) to work as Hive metastore and could combine 20 EMR cluster’s meta data into a single RDS, which avoids the data loss even by terminating the EMR. Mounted Local directory file path to Amazon S3 using S3fs fuse, to have KMS encryption enabled on the data reflecting in S3 buckets. Worked on EMR Security Configurations, to store the self-signed certificates as well as KMS keys created into it. This makes to spin up a cluster in an ease manner without modifying permissions after the call. Configured Apache Hue’s file browser and S3 browser operations and created User’s home directories. Noticed different Name node port number in Hue, when running on different protocols, and was able fix the default settings for their access and approval. Applied Auto scaling techniques to scale in and scale out the instances with given Memory out of time. This helped in reducing the number of instances count when the cluster is not actively in use. This is applied by even considering Hive’s replication factor as 2 leaving minimum 5 instances running. Triggered Put Method for Audit and Security log files residing in S3 bucket to Middle ware applications, using AWS Lambda with Restful API’s.

Worked on Rest Web services as well as Node Rest framework for backend services, used Mongo DB (NoSQL) for database services. Developed and implemented a Python boto3 Lambda function that acted as a Login service taking encrypted user credentials and providing back AWS Cognito tokens (Access, Refresh and Identity). Performed efficient delivery of code based on principles of Test Driven Development (TDD) and continuous integration to keep in line with Agile Software Methodology principles. Used AngularJS, jQuery UI to add functionalities and effects like Accordion, Infinite Scroll bar, Slider bar, Draggle/Droppable, Resizable, Progress bar. Supported many other projects build and deployments issues with Jenkins CI/CD pipelines. Dynamic implementation of SQL server work on website using SQL developer tool and Experience with continuous integration and automation using Jenkins and Implemented Service Oriented Architecture (SOA) using JMS for sending and receiving messages while creating web services.
