LiquidTap is a food and beverage menu manager for small businesses.

I co-founded the company and co-developed the software, which operated as a Software as a Service (SaaS) application. I was a full stack developer, and my main focus was writing code for customer accounts, menu data, and the routes and API of our application. Essentially, I developed the Model View Controller (MVC) of our application.

LiquidTap was sold to by Bevcheck in 2022.

With LiquidTap you could:

• Create and edit menus and display them online and across multiple TVs
• Print your menus or embed them on any website with one line of Javascript code
• Import your beer menu from your Untappd account
• Integrate your menu data with third-party Point of Services (Pos) like Lavu
• Save your sales data and download them to your computer
• Developed using Laravel, PHP, MySQL, and Javascript
• Other skills and tools used include Git, Bootstrap, PHPUnit, RestFul API, Homestead, API development and testing, Postman, SQLWorkbench

Develop software to automatically generate test cases.

At Intel, I worked as part of a small team that developed from scratch a test case generator. Where it would take hours for a person to write a test case, our tool could generate a brand new test case in seconds. My primary role was to write a plugin that would translate XML data to a valid test case that could be run by Anritsu network simulators.

My tasks at Intel:

• Develop the test case generator that takes field traces and creates complete end-to-end test cases
• Write from scratch a Python plugin to generate XML-based test cases
• Troubleshoot and write software patches to the entire test case generator in tool which was written in C++, Matlab, Python, and XML
• Execute test cases for the Intel mobile platform technologies, e.g. regression testing

At Nash, I performed system and integration testing on the Small Cell network product we were developing. We worked in a continuous integration environment and used tools such as Jenkins and Jira to write and track issues.

My tasks at Nash:

• Develop and execute test cases based on specifications and customer requirements
• Integrate and test network protocols and technologies
• Write and perform automated test scripts for regression testing
• Integrate the development of software features into various hardware platforms
• Follow a Continuous Integration strategy using tools such Jenkins for build maintenance, Jira and Trac for ticket management, and Subversion for version control

At T-Mobile, I performed mobile terminal interoperability testing on vender mobile phones, for example from Samsung and Nokia. I ensured the mobile phones passed network standards such as 3GPP as well as T-Mobile’s own standards.

My responsibilities:

• Perform acceptance testing of mobile devices to ensure interoperability with the T-Mobile network
• Write automated test scripts for protocol testing
• Ensure devices satisfy T-Mobile International requirements and specifications using both manual and automated test cases
• Test mobile devices from major device vendors
• Write, edit, and review test cases for T-Mobile International

Software support for GSM and GPRS core network:

• Write software patches on live networks to fix bugs and reverse design defects
• Analyze system issues in core network code and report findings to software development
• Support system upgrades and maintenance, and be on 24-hour support in case of network outages
• Verify issues and take logs during system integration of new features and equipment
