  • Day to day work spans multiple dimensions, hands-on coding, quality assurance, pipeline designs, troubleshooting etc to name a few.
  • Designed and built two end-to-end forecasting engines using time series techniques and ensemble methods using both CPU and GPU based distributive computing. For CPU, used spark library mmlspark and pandas-udf. For GPU, utilized the RAPIDS library and dask-cuDF for multi node multi-gpu forecasting.
  • Developed a custom arima module to automatically determine arima parameters using pyspark which was ~3x faster than auto arima based on the results of 2 projects.
  • Research into latest techniques, technologies and algorithms to extract and utilize any beneficial aspect of it.
  • Provided comprehensive analysis and recommend solutions to address complex business problems and issues.
  • Designed and built efficient pipelines and ETL's for optimal flow of data from/to databases.
  • Worked on many POC's for companies like Mondelez, Walgreens, Adidas etc paving the path for conversion to full time projects.
  • Worked on real time deployments for projects like Flowers Foods and used ML OPS techniques for active monitoring of the system resulting in a stable process and an alerting mechanism in case of anomalies.
  • Built an order suggesting algorithm to consume sellin, point forecasts, inventory along with other business requirements to propose route optimal order suggestions for planners.

  • Improved the quality of the weld by finding the most influencing process parameters using ML and optimizing it.
  • Used feature selection techniques like RFE, feature importance's, f-tests, correlation matrix etc to reduce the dimension of the data.
  • Most influential and least influential features were identified and optimized which led to an improvement of 11% in the
    weld quality.
  • Parametric optimization to replace expensive and time taking simulations using historical results. A ML model with ~5% deviation was developed reducing the number of simulations required and saving ~2 days of effort per project.
