Replicated Key-Value Storage (Tech Stack : Java and Android Studio) April 2019 - May 2019

+ Designed and implemented a Dynamo-style key-value storage in android that handles Partitioning,Replication and Failure handling.

+ Durability and Availability: Partitioned and replicated the data using consistent hashing which is also used for node key distribution.

+ Reads, Writes and Failure Tolerance: Used a sloppy quorum technique together with object versioning to ensure linearizability.

+ Failure Detection and Node Recovery: Detected failed nodes and implemented a decentralized replica synchronization protocol. Image Colorization using CycleGAN (Tech Stack : Python, Google Cloud and keras) Feb 2019 – May 2019

+ Investigated on a promising method for unsupervised image colorization which artificially colors grayscale images using CycleGAN. Reservation system (Tech Stack : Java, Swing and Eclipse) Feb 2019 – May 2019

+ Developed requirements, designed classes, and created tests validating the well-designed reservation system with GUI. Simple DHT Chord (Tech Stack : Java and Android Studio) March - April 2019

+ Designed a simple DHT based on Chord in android app that handles ID space (re)-partitioning, Ring-based routing Node joins. Group Messenger Application (Tech Stack : Java and Android Studio) Feb -March 2019

+ Designed an android group messenger application that can communicate with other devices using this chat application.

+ It guarantees FIFO and TOTAL ordering and handles failures which implemented using socket-client programming. Prediction of handwritten digit (Tech Stack : Python and keras) October 2018

+ Recognized a 28*28 grayscale handwritten digit image among 0, 1, 2, 9 on USPS and MNIST Dataset using Neural Networks, Random Forest, Logistic Regression and Support Vector Machine classifiers and then ensembled gave 97 maximum cross accuracy. EXPERIENCE
