I have 26 years of working experience in IT industry. During this period, I worked in various roles and capacities; Data Scientist, Data Analyst, Application Architect/Designer, Technical Team lead, Project Planner and Scheduler, Business Analyst, System Analyst, Web Usability Designer/Analyst and software engineer. Experiences molded me as a strong team player. I propose new ideas in applying AI to business process and operation and create business value to the organization. I have strong drive to learn new technology, continuously working to improve my knowledge and apply it on job to produce the greatest and best quality of work.

I have extensive experience in predictive and prescriptive analytics for real world problems using machine learning and deep learning algorithms. I created AI models for supervised learning, unsupervised learning (clustering), Regression and Reinforcement Learning algorithms. Worked in big data platform like AWS machine learning, Google machine learning, Cloudera and Hortonworks. Worked in different AI Tools such as Domino Lab, Data Robot, AWS Sagemaker and Google Colab. Following tasks are performed in the AI work:

1. Extract data from different data sources, combine and transform the data and load the final data into a repository

2. Data exploration using visualization tool and descriptive statistics

3. Perform Model Experiments

3. Feature extraction or reduction from data

4. Build AI models using Machine learning, Deep Learning and Reinforcement Algorithms

5. Hyper parameter tuning of the model

6. Interpret the results of AI models and provide reasons for the predictions with visualization

8. Build, deploy and monitor model at production environment in cloud and non-cloud platforms with CI/CD capabilities

9. Automate the various tasks in data processing like data collection, data wrangling, load into repository using data engineering pipeline 

10. Automate the pre-processing of data and model training using pipelines

11. Automate the prediction process (in the case of batch processing) using pipelines

10. Present the work done to the stakeholders, get feedback and improve the model with the suggestions received

11. Build feature store with data versioning

12. Build model registry with model versioning

13. Store the artifact and model performance metrics

14. Monitor model performance in production

15. Work with Stakeholders to collect requirements and assist Product Owners to convert those requirements into EPICS and User Stories. Plan the work with Scrum Master and other scrum team members

Major awards:

• Won the 3rd place in the AI grand challenge conducted by Northrop Grumman (NG) at organizational level.
• Selected as Finalist for 2021 President's Excellence Award at NG
• Won the Best Project award in Quality Symposium at NG

I have a PhD in ocean structural engineering from the topmost school, Indian Institute of Technology, in India. I have a MBA degree from Johns Hopkins University. I have certification for Data Science, Apache Spark and Deep Learning with TensorFlow. Currently following a professional AI certification from Stanford University.

I am attaching my resume for your review and kind consideration. I am looking forward to meeting with you at your earliest convenience and discuss this career opportunity further. Thank you for your consideration.
