Studies & Job (How you have been transformed from various past roles to present ?)

  • I did Bachelors in Information Technology and continued Master's in Cyber Security.
  • While doing Masters, I started an Internship program with Symantec.
  • Initially I worked with Managed Security Services Team develops and maintains SIEM tool. There I learned more about data architecture include multiple network devices, linux servers, SQL servers, log parsers, large data flows from network to on-premise servers and application end point. There I was helping team with linux, shell scripting and python skills. I was writing pythons scripts to do a log files transfer from one server to another server based on watchdog events(on create, on delete, ssh). Generated more device based mock logs files for the development and testing.
  • After 6 months of Internship, I moved to Norton Product Team, builds the Antivirus product for Mac OS and iOS products. There I was developing and contributing to Python automation frameworks for different teams uses like simulating security scenario includes bruteforce password attack, DOS attack, scan virus files, port scans to list open ports and vulnerability scanner to list outdated packages or software in the host machine.
  • Then I moved to CEB (Corporate Executive Board), later acquired by Gartner. First, I was hired for maintain and support NLP Web Product that predicts the best hire for the job using multiple resumes as input. It was built using Python in backend and Java in Front End, runs on Tomcat on-premise Server. Then I moved data analytics team inside Gartner. There I have started working as individual contributor as well as a team player. My roles includes collaborating with Stake Holders from Sales/Marketing/Events team understand their problem and provide data solutions from initial stage to final deployment including maintaining code repo and performing CI/CD. I have developed products like
    • Email Bot (classifies the emails into 4 categories - OOO, Left, Bad, Others and sends weekly and monthly reports. This report helped Sales team to manage maintain contacts status easily. Continues the membership company even the people left the company. - Python(nltk, pandas), MongoDB)
    • Competitive Dashboard (Scraps the data of competitor from their websites, stored and creates the dynamic chart to understand more about competitors - Python(Scrapy, requests), Elasticsearch, Kibana)
    • Database - Table values cleaner (Lots of survey data withe bad characters and format. Created a machine learning prototype to cleanse the values based on right values. - Python(scikit, pandas))
    • Universal Data Scrapper (created a dynamic tool to scrap the data about any company from the popular Websites, news channel and blogs)
    • GCP to AWS data migration (Moved BigQuery Datasets to AWS S3 - Python, Pyspark, Shell, API)
    • Worked with Data Science Team in building Recommendation Engine, does ETL (From On-premise Oracle Server to Data lake using sqoop, transform data with spark and created tables in Hive)

      In Gartner, gained lots of experience in terms data, cloud knowledge and building data end-to-end solutions

  • Then I moved to ABCO - Optum - United Health Group, I worked in two solid Projects in 1.10 years span
    • Initiative Manager Product - Acted a sole Product owner and Full Stack and DevOps Engineer, managed an end to end operations, develop and enhance the product features listed for GA. Worked in backend (Django python), frontend (ReactJs), PostgresSQl, infrastructure tasks (Sonar, Splunk, New relic and Nagios) and CI/CD (Bamboo).
    • Data Engineer convert Oracle Queries to Spark queries. Written UDF for the custom procedures/functions available in Oracle. Written spark solution on top of large JSON data and create flat tables using case classes. - AWS EMR, Spark, Scala, Bash, HDFS, Github, Jenkins, Sonar, Terraform

      In Optum, learned more about different technologies and stacks, how are they relying on one and another? adopting them while working in Agile is more challenging.

  • Then worked as Senior Associate Manager at Eli Lilly
    • App Modernization - eCSP - Convert the Clinical Supply Platform legacy Application (Fuse and java application) to a cloud based solution (AWS Lambda, Cloudwatch, SNS, Fargate, RabbitMQ, S3, DynamoDB). Developed the Python framework that has pre-commit hooks to maintain the coding standards, unit test cases and code coverages.
