Working Prototype

A working prototype that I designed and delivered in as fast as three days.

This assignment was part of an application process for another project and had to be finished within three days. I tackled the problem, successfully delivering within the given deadline—which was a pretty brutal time constraint. I completed the working prototype, including the demo, screencast, and design specifications.

Created the whole application including all back-end systems and services such as payment gateways, shift planning, emailing, and accounting.

Brandhearts

Brandhearts is a SaaS solution that allows merchants (usually eCommerce and other SaaS companies) to create "smart" referral campaigns. Smart means that the tool reacts to a user's behavior and changes its appearance, incentive, or messages in order to convert the customer into a referrer. It applies machine learning and big data algorithm to do so.

I created the whole system from scratch utilizing Windows Azure, Windows Azure ML and a high-performance ElasticDB solution to handle the huge load of client side requests.
