I worked as a full-stack engineer, building features for the web app, coding in Elixir and React, and was a lead developer on the mobile app built on React Native.

Freshbooks (via Toptal)

http://www.freshbooks.com
One of the leading cloud accounting apps in North America, operating globally.

I served as a full-stack developer on the marketing enablement team within a company, building front-end features in Ember.js and back-end features in Python and Ruby.

Hospitality Back-end System

I led a team of engineers building the system using Python/Django on the back end and React on the front end.

Ad Tools | The Onion

Ad tools is a web-based application for creating and monitoring ad campaigns at The Onion. The application serves as an integration point of multiple systems in a clients' organization (their core business system and third-party systems for tracking campaigns and ad placements).

The purpose of the ad tools application is to give ad ops a better insight into running campaigns and placements by being able to find all information in one place, as opposed to being scattered into multiple third-party systems.
The system was built using Django on the back end and Bootstrap and Backbone.js for the front end.

mediPx.com

mediPx brings together buyers and sellers of medical supplies and equipment via a free, easy-to-use online marketplace. Registered users can utilize the platform to buy, sell, and auction medical equipment. Users can auction their used or refurbished medical equipment and supply, create purchase lists on which the sellers can offer quotes, or simply purchase items from sellers' inventory.

The back end was built on Django, while the front end is HTML5 and CSS3, relying primarily on the Bootstrap framework.

DMS Management System

This system enables administrators to manage content (videos, images, scrolling text, etc.) played on any number of clients connected to the server. The system also provides monitoring of critical hardware parameters and raises alerts accordingly. The server can remotely control client hardware (e.g., change parameters of client screens, restart hardware, manage client working hours).

The server provisions new versions of client software to the client itself for auto-update.

The server-side application is written in Python (a combination of Django and a custom WebSocket server), while the client-side is implemented in C# (deployed as Windows services).

Nahundi

Nahundi is a system for managing dunning and distraints. It provides the ability to track payments and debts with a printing module that enables the automatic generation of dunning and distraint documents. Several Croatian companies use it to support their debt collection.

Nahundi is written in Java, with page rendering implemented using FreeMarker.

Pharmacy Web Shop

The system was built in Python (Django) with a PostgresSQL database, with an HTML and jQuery front end based on Twitter Bootstrap, deployed to Heroku.

Aaber-trade.com

http://saber-trade.com
SABERTRADE enables investors to execute trades efficiently based on the investment theses from their favorite experts, publishers, and creators.

It is a web application built in Python and Django on the back end and React and Next.js on the front end. The client utilizes a GraphQL API to communicate with the server.

The app is hosted on Heroku.com and Vercel.com.

A Netsuite to Sanity Bridge

The client is an award-winning, independent design and manufacturing company headquartered in Kingston, New York.
