Senior Machine Learning Engineer

2020 - 2020
Liberty Defense
  • Designed and showcased a deep convolutional neural network for the prediction of threats.
  • Involved state-of-the-art image segmentation and detection such as Mask-RCNN for the segmentation of threats (e.g., in cases hiding guns or having guns with them).
  • Achieved remarkable accuracy of (95%) in detecting cases carrying guns. Used the TensorFlow library for implementation. Trained on CUDA GPUs.
Technologies: Deep Learning, TensorFlow, Keras, Python

Senior Software Engineer

2018 - 2019
Home Depot
  • Designed and implemented deep models for search and personalization. The task was to rank items returned by a search engine for different search phrases with respect to their relevance and satisfaction of users.
  • Trained NLP models implemented with TensorFlow and trained on GPU. Used recurrent neural nets along with siamese networks. Integrated multiple modalities such as user behavior.
  • Required preprocessing scripts written in the Spark framework to generate and preprocess large datasets.
Technologies: Deep Learning, TensorFlow, Python

Software Engineer Intern

2018 - 2018
Verizon Connect
  • Developed an app using advanced recommender systems for recommending the best matching shopping places for drivers. Used and sorted through a large amount of data accumulated in data clusters.
  • Utilized driver behaviors as well as their personalities and demographics to train an integrated deep recommender system. The data was accumulated from a large number of vehicles consuming the product (dongle).
  • Integrated two types of recommender systems; the content-based filtering methods, and the collaborative filtering method. Content-based modeled individual personal information, while the collaborative modeled driving behaviors and habits.
  • Used TensorFlow and Python to achieve the task using both collaborative and content-based filtering approaches. Trained end-to-end.
  • Achieved significant performance in predicting the preference of drivers for their shopping center of interest.
Technologies: Deep Learning, TensorFlow, Python

Data Analyst Intern

2015 - 2015
UCB Pharma
  • Developed a deep learning pipeline based on auto-encoders to predict Parkinson's disease from claims data. The goal was to predict whether the person has Parkinson's based on past visits at different doctors.
  • Utilized the H2O library in R to implement a deep network from features describing the patient's past medications and diagnosed codes. Achieved an impressive prediction performance of about 90%.
  • Identified cases in the early stages of the disease (to receive a more successful treatment), by using the trained model to find trial cases sooner.
Technologies: Deep Learning, R

Prediction of Threats from Radar Generated Images

Developed a deep convolutional neural network for the prediction of threats (i.e., persons carrying guns), in real-time. This project was the analytics part of a platform developed by the company I had collaborated with. The overall platform included using a multi-static radar system that generated 3D volumetric images and a Kinect camera to find the distance to the camera. The radar phased data were then preprocessed and combined with the Kinect image to generate a 3D volume. We used state-of-the-art deep image segmentation and detection to uncover threats. This project involved the use of popular deep architectures such as R-CNN, Fast/er R-CNN, and Mask RCNN.

Using NLP for Improving Alignments of High Throughput Reads

Worked on a pipeline based on Siamese networks to expedite the read alignment score, which can improve and accelerate the assembly process. The readings can potentially belong to different variants and genomes, and we were interested in making sure contaminated samples will not lead to inferior contig quality.

Using Large Language Models for Analysis of Adherence to Clinical Guidelines

The objective of this project was to assess the compliance of submitted documents from healthcare providers with the required criteria and clinical guidelines. These guidelines serve as curated medical documents developed by doctors and clinicians to ensure that treatments are delivered according to the standards of care. The primary focus was to verify whether the providers had completed all the medically necessary tasks for any performed medical procedure, emphasizing the importance of adherence to these tasks.

Developing Advanced Question Answering Models for Information Retrieval from Medical Documents

The objective of this project was to design, develop, and train advanced transformer-based models capable of accurately answering medical questions. The approach employed retrieval-based techniques followed by question answering to extract relevant answers for a given query. By leveraging these methods, the project aimed to enhance the accuracy and efficiency of obtaining precise medical information in response to specific inquiries.
