  • Used the Ryu SDN framework to dynamically add OpenFlow rules for test packets on the data-link layer.
  • Tested packet tracing along with generating traffic with the Scapy library.
  • Improved logging on the C/C++ level by migrating custom logging implementation to log. Some logs were lost with the previous implementation when the app service crashed.
  • Experimented with the spdlog library to see if it's reasonable to migrate to spdlog in the future.
  • Implemented all the services with gRPC and Protobufs. Added health-checking services to the tool. Used Open vSwitch with Wireshark to debug and trace the packets.

Machine Learning Researcher

2017 - 2019
  • Participated in DIIN in Keras, the ICLR reproducibility challenge.
  • Published a report on the reproducibility of a DIIN neural network architecture for natural language inference using Keras. The source code can be found in my projects.
  • Handled the Keras implementation of the complex neural network called R-net designed by Microsoft Research for question answering (R-net in Keras).
  • Published a blog post on the implementation details and reproducibility of the R-net paper.
  • Completed my university capstone project: Word2morph2vec.
  • Designed an end-to-end pipeline for extracting "linguistically accurate" morphological vectors for given words or sentences. Experiments were tested and evaluated on the Russian language.

Android App Developer

2017 - 2017
  • Created several internal monitoring tools (Android apps).
  • Implemented activity tracking on each internal project of the employees. We used an MVVM design pattern with an Android data-binding library in that project.
  • Used RxJava/RxAndroid heavily for easy network request manipulation and fetching information from the database.
  • Authenticated with Firebase, and most of the information was kept in the Firebase real-time database, which we used like a REST endpoint.
  • Developed with a team several libraries which help deal with code easily in the MVVM world. One was creating and populating lists without adapters; just a list of the view models was enough.
Technologies: RxJava, Firebase, Android

Machine Learning Engineer

2016 - 2017

  • Built a C++ neural network library for providing low-level neuron-based operations instead of layer-based ones.
  • Implemented a neural network for person segmentation (with Lua/Torch). Given an image, the network finds a person inside it and outputs a mask corresponding to that person.

ABCDE: Approximating Betweenness-centrality Ranking with Progressive Drop Edge
A graph neural network approach to approximate betweenness-centrality ranking in Graphs. Experiments on real-world and synthetic datasets show that our algorithm is faster in inference and requires several times fewer resources and time to train.

This work is submitted as a journal paper.

EPE-NAS with DARTS and for faster neural architecture search.

PyTorch Lightning implementation of differentiable neural architecture search with benchmarks on both DARTS search space and NasBench-201 search space. The approach is tested on several datasets, including CIFAR-10, CIFAR-100, MNIST, Fashion-MNIST, and Imagenet.

Neural Network Library
This library provides a low-level API to perform operations directly on neurons to utilize individual neurons in a neural network better. The current neural network library implementations are concentrated on layer-based operations.

YerevaNN Project Source Code and Additional Details

I published a report on the reproducibility of a DIIN neural network architecture for natural language inference using Keras. The code is open source and available on GitHub.


I published a blog post on the implementation details and reproducibility of the R-net paper.


I developed an end-to-end pipeline for extracting "linguistically accurate" morphological vectors for given words or sentences. The system is based on FastText and COMBO. Experiments are tested and evaluated in the Russian language.

Source Code:

I architected a convolutional neural network with custom attention interaction and used a bidirectional recurrent neural network as a baseline.

Image Coloring
Image Coloring uses neural networks, and this implementation is a Wasserstein GAN for turning greyscale images into colorful ones.

Three Experiments:
• A simple approach: colorize a greyscale image in the lab space. Given the L channel as an input, predict AB channels.
• Classification: the AB space was divided into chunks of colors and treated as a classification problem.
• Wasserstein GAN: used generative adversarial networks to predict AB channels with both first and second approaches.

Spell Checker

Spell Checker is an app designed for editing and correcting texts. The app works offline and supports several languages, including Armenian, English, and Russian. The app currently has more than 100,000 downloads.
