FlexDealer Total Control Platform

I built from scratch a website management and inventory control platform for FlexDealer. The initial version was developed in 2007 and is still active today with various revisions occurring throughout the years. I began as the sole developer and helped them grow the team into a full marketing and development agency.

Swop App

I developed the back-end, database, and server infrastructure for the Swop app which launched to the App Store and Google Play Store in the fall of 2016. I worked closely with the front-end app developers to integrate the API into the product. Launched for only three weeks as a pilot test run to 300 users for information gathering purposes before being pulled to plan the official version.

Rising Star Award

I led the development of an automotive marketing, website, and inventory platform (including a custom CMS and custom integrations) that was presented with the Rising Star award in the annual Automotive Website Awards (AWA). The platform and company were built along with the co-founders and the rest of the FlexDealer team.

Enterprise Automation Testing Platform

I served as a team lead for the development of an enterprise automation testing platform. It was designed for internal use, but was quickly noticed by others and was eventually licensed by the company to a partner (a very large software and hardware vendor) for millions of dollars.

For this to be built and licensed, I worked as a liaison not only to the other developers, but also to the open source software community, and legal and sales teams (serving as the main technical salesperson in the deal).


A set of API endpoints for following, unfollowing, and listing followings and followers for a user. It highlights apiDoc style documentation, code commenting, data validation, error reporting, database interaction (via Sequelize), async/sync programming, and more.

This code is intended to be run via Hapi.js as a Node.js server and also using Sequelize against a PostgreSQL database.


I maintained the back-end APIs and infrastructures—creating endpoints and processes and working closely with UI developers for implementation. I also integrated the Instagram's APIs for authentication, data processing, and interactions. Without neglecting my other duties, I also performed language processing, classification, and recognition using IBM Watson's data APIs.

I also maintained a very large PostgreSQL database, optimizing storage and processing. I set up, supported, and optimized the AWS back-end infrastructure. In addition, I created and maintained the back-end test suites. Reviewing the code for other developers was also my responsibility.
