Selected Projects

OpenWeb Moderation 2.0

A proprietary platform for OpenWeb (formerly Spot.IM). The mission was to build a complete infrastructure for ingesting, tagging, and moderating millions of pieces of user generated content per minute across all of the OpenWeb platform. The project was build with high scale, reliability, and efficiency in mind.

The project was built using an event sourced architecture with several microservices managing different parts of the system. It was written in Go, utilizing SQS and Kafka as event queues, and deployed on Kubernetes. After the creation of the system, a case study was done with Google's Jigsaw team on the effect of nudges and real-time moderation on users.

Starship Web Server

A project built as a personal endeavor, to build a high speed web server in pure Elixir.

The project began with me wanting to learn how to build a reactor designed web server that can overtake the TechEmpower benchmarks for Elixir and Erlang's current benchmarks. It expanded a lot as I learned how the entire HTTP protocol worked, and I am currently working on expanding it into a complete webserver.

Rulebase Classification Algorithm

A proprietary classification algorithm for Signals Analytics. The project entailed designing and developing a Natural Language Processing algorithm to take massive amounts of data points, each with its own text description, and then classify what each data point is talking about, based on a set of rules provided.

After the application was built as a monolith, it was then broken it up into decoupled microservices to deploy as highly scalable cloud-based workers. The project is developed primarily in C# and ASP.NET Web API, using ElasticSearch as a search algorithm, and RabbitMQ as a task queue.

Tableau Model and Algorithm Design and Implementation

Several proprietary models for extracting analytics and insights designed and engineered for Signals Analytics. This project entailed analyzing scientific, social, and market data in various industries, and developing models in Tableau to extract valuable insights from this data to deliver to clients.

In addition to designing analytics models, complex visualizations were developed to display data in new and innovative ways, creating algorithms to solve specific problems for the company, as well as developing new features for the company’s platform. The project is developed primarily in Tableau, using Tableau’s internal SQL-like language.
