Work History

Lead Data Scientist

Majesco
01.2023 - Current
  • Building a Copilot Chatbot with Azure Open Services and leveraged Azure AI Search for Retrieval-Augmented Generation, while also developing pipelines for evaluating and verifying generated responses, specifically for the chatbot and Copilot project
  • Finetuned GPT models using Azure OpenAI Studio, and evaluated the finetuned model's performance against the original
  • Using various techniques, such as openai functions, for Intent Classification of user questions, in order to provide GPT models the best fit documents for answering the question
  • Setup a end-to-end pipeline for: retrieving data, cleaning it, trainining various scikit-learn models on differernt data preparation techniques, hyperparameter tuning, evaluation of different models based on previous steps (including autogenerated plots and metrics), and deployment of models in Azure.

Data Scientist

Majesco
01.2020 - 01.2023
  • Performed exploratory data analysis using Jupyter Notebooks to initially determine what potential domain specific problems could be solved using ML
  • This involved linking text data from different forms to images, then determining if there is enough of that data to train a model
  • Then performed data preparation for training, normalizing the data and migrating over to an AWS S3 bucket
  • Trained various model, such as ResNet and Yolo, in PyTorch Framework for photo classification and object detection
  • Effectively determined model performance and areas of improvement through auto-generated jupyter notebooks
  • Used tactics to improve model performance, like active learning and hyperparameter tuning
  • This included building up frameworks in python to streamline labeling and document different versions of the model
  • Created regression models using SciKit Learn to classify different insurance case types
  • This consisted of combining text and image data to find the key differences between Residential and Commercial cases
  • Generated insurance-context word embeddings using text data from cases
  • Data had to be heavily cleaned and normalized, and then was able to fine-tune Word2Vec and GloVe embeddings
  • Then used different unsupervised clustering algorithms to see if any classes naturally arise
  • This was useful to determine if the word embeddings became insurance-specific
  • Visualized word embeddings using multiple different decomposition methods, like PCA and t-SNE, for dimensionality reduction in order to better plot values.

QA Analyst

Utilant (Majesco)
01.2018 - 01.2020
  • Developed test plans and cases to assure that the software produced behaved up to company standards
  • Setup API testing in Postman, using collections and testing scripts written in Javascript
  • Wrote automation code using OpenSelenium to automate regression testing
