Mobile Mask R-CNN
December 1, 2017 – December 1, 2018
+ Worked in a team to convert the Keras/Tensorflow Mask RCNN’s Detection Layer to Tensorflow operations for cross-environment serializability. + Debugged aforementioned Mask RCNN model to be compatible with Tensorflow Mobile, extracted Tensorflow Protobuf model, and successfully exported more operations to the built libtensorflow_inference.so library. Wrote initial inference interface that accurately deciphers predictions from an architecture with 2 inputs, 5 outputs, and 2 parallel networks. + Replaced the Feature Pyramid Network’s ResNet50 backbone with MobileNetV1 for better performance on embedded devices, reducing inference time to 62% of the original speed.
Planet: Understanding the Amazon from Space (Kaggle competition)
April 1, 2017 – June 1, 2017
Created the 9th place (of 939 teams) solution for the "Planet: Understanding the Amazon from Space" Kaggle competition using convolutional neural networks, boosted random forests, and weighted-voting ensembles of submissions. Goal was to automatically label satellite images of the Amazon rain-forest, where labels assigned to an image ranged from 1 to 17 classes (agriculture, primary rain-forest, water, etc.). Used Pytorch, Keras, XGBoost, and Scikit-Learn/OpenCV2 for our solution. Pretrained models leveraged were Resnet[18, 34, 50], Densenet[121, 169, 201], VGG[16, 19], and Inception[V3, V4].
CVE-2016-3897

Twitter Analytics
October 1, 2014 – November 1, 2014
Designed and implemented a web service that uses REST interface to respond to queries on a large twitter data-set (1 TB) which has been transformed and loaded into a database. • Hosted the web service on Amazon EC2 instances behind an Elastic Load Balancer • Designed an efficient Extract, Transform and Load (ETL) process to convert the given dataset (JSON) to comma separated values that can be imported into the backend database • Ran the ETL using Elastic MapReduce offered by Amazon Web Services • Selected MySQL as the backend database after comparing its performance with HBase for the given queries • Scaled the MySQL backend using horizontal replication. (The queries were read-only) • Team size: 3 students
