Experience



Viagio Technologies

07/2023 - Current

In my time at Viagio Technologies I had the opportunity to work with a lot of very talented engineers, architects, designers, and managers all working as a highly effective team to deliver exceptional software to our clients. I also had the opportunity to work with many client stakeholders, managers, developers, testers, and designers to help bring their vision to life in exceptional mobile applications.


Senior Mobile Software Engineer

Swift Project

Worked on a small team to update a native swift iOS application with additional features requested of the client.

This application update, although simple on its face (implement deep linking, new RSS feeds, etc), ended up being quite complicated. The application was originally developed by another agency with proprietary modules and a very complex abstraction structure. This created a opportunity and necessity to really dive in to understand the app and its architecture.

Swift XCode Git Modules BitBucket

iQ Pro Mobile App

On this project I had the opportunity to lead a small team of completely green Flutter developers, designers, and product people. The goal of the project was to implement payment processing Flutter app where the user could manage and makes sales, add and edit customers, process other forms of transactions, and switch between multiple organizations using the clients proprietary payment processing system.

Additionally I was able to develop my leadership skills as a Sr. Engineer and be the Sr. Engineer in a client facing position, make architectural decisions, do code reviews, develop and implement a CICD pipeline, manage deployments through the app stores, lead demos, consult on requirements, and worked closely with UI/UX designers to implement designs that were not only cost effective and easy to use and understand, but also did not sacrifice accessability, usability, and design.

Technically the application implemented an OAuth login flow through an Azure AD B2C tenant, utilized Riverpod for state management, developed as many reusable widgets as possible to reduce code duplication, and implemented several complicated features.

Xamarin Project

On this project I was tasked with leading a small to implement changes required by Apple in how a Xamarin application managed in app purchases and bring them inline with Apple's guidelines.

Technically, this project was very straight forward in that we implemented James Montemagno's InAppBillingPlugin Nuget package and in a new view allowed the user to purchase and restore their subscription.

Cornerstone National Insurance app

Developed an insurance application in React Native that allowed users of a local insurance agency to manage and view policies, cards, and other information related to their coverage. Additionally help setup the base of the application to be white labeled and sold to a variety of insurance agencies who use the Guidewire platform for managing their insurance backend.

After successfully entering the Guidewire market this app was eventually spun off into its own startup business.

Mobile Application Developer I & II

Xamarin

Developed a mobile application that allows for store associates to complete Buy Online Pickup In Store and Ship From Store. Application communicates with our vendor, Radial's, APIs and streamlines the product picking and packing process while enabling the users to be more accurate finding products with interactive high definition images and instant feedback via utilization of scanner built into the device as well as saving money across the board with labor time saving and eliminating paper waste.

Wireframed, architected, and initially developed an application that allows stores to access their current inventory and make changes while on the floor and interacting with customers. This application will save employees time by greatly simplifying the process and allow them to edit inventory while on the floor and not in the backroom so their changes will be more accurate and they can continue to assist and sell to customers.

Developed a mobile application using C# and Xamarin targeting an Android devices used by Hallmark Gold Crown retailers that provide those retailers with access to sales information and data, daily goals, real-time goal progress, and the ability to update and calculate target and stretch goals. This along with other key performance indicators allows the retailers to have a better understanding of how their current sales are compared to their set goals and helps drive sales. Sales data was transferred from a vendor's api and store information from a ServiceNow api into our app via an Apigee gateway. The application was developed using git in Azure DevOps in the Agile/Scrum methodology.

Visual Studio App Center

Utilized Visual Studio App Center to setup CI/CD pipelines to automatically build our application and release the APK to our partners for deployment to the Gold Crown Network.

API Development

Developed new functionality in automation services to create and update users and contacts from data in Microsoft Active Directory and load them into Salesforce as well as a process to deactivate a user when they are removed from Active Directory. Additionally developed new functionality in an ASP.NET webpage to move images from an existing database to a new MongoDB database and then created a process for automatic reporting of the transfers and the associated meta data.

Salesforce

Created a process to limit the duplication of accounts being loaded from SAP to Salesforce and automating 10+ hours a week of manual checking and removal of duplicates. Developed custom apex code controller for a Visualforce page that dynamically pulled data from business created fields and provided easier to read and understand error messages for both future admins and users. Also created process to allow business users to easily update text on a Visualforce page with updating code.

Other Miscellaneous Experience and Notable Projects



Viagio Flutter Intranet Project

Working off and on between client projects myself and other engineers built a Flutter generator that would auto generate a Flutter project with user values and created an app that mimicked the tools created for our internal intranet to help calculate time estimations, associate skill lists and interests, and other similar tools. This application was pretty bare-bones, but could authenticate with our Azure AD and perform the basic functions of the intranet web app that was already deployed.

Hallmark IT Hackathon 2018-2020

Working with another coworker we plan and put on the Hallmark Hackathon. We work to get CIO, SVP, and VP support and funding to put on a two day hackathon for all of Hallmark to participate in and make amazing and innovative projects. Part of the process includes designing and ordering T-Shirts, scheduling work spaces and times, ordering and providing food, and recording and distributing the results to other senior leaders allowing them to see the awesome work and spin up projects to make them reality.

Hallmark IT Hackathon Winter 2019

My team and I worked on an idea I had to develop a series of chat bots. The original purpose was to provide a chat bot to take care of basic questions and tasks inside of Microsoft Teams. In the end we developed several different applications on different platforms. First we developed a conversational chat bot using Azure Bot Service and C#/.Net that could run on Teams. Second we created Microsoft Flows to kickoff different jobs cued from the chat bot. Third we developed a Microsoft Power Platform based chat bot who could do simply actions. Fourth we used the powerplatform to create a basic mobile app as another place for the chat bot to live and as a way to engage in employee recognition. Additionally we used Sharepoint and a SQL server as backend for data storage. As you can see a small idea bloomed into a variety of use cases and on different platforms all with their own pros and cons.

Hallmark IT Hackathon Summer 2019

Pocket Identifier

Worked in a small team to develop a image recognition application to identify card pockets in card racks. Specifically looking for pockets that hand only envelopes, empty pocket with a pocket identifier (The card the says "Mother's Day, Birthday, etc"), and an empty pocket without a pocket identifier or an envelope. After two working days, tagging thousands of images, and hours of training we were able to identify with about 73% accuracy. Several challenges were encountered including the time to stage that many images, the variety of cards confusing the algorithm on what a card is, and finding a empty pocket with no identifier because the plastic behind it is clear and just showed another card. Technologies used: Azure Cognitive Services and CustomVision.ai.

Huddle Space Remodel

Worked with facilities, infrastructure, and the CIO to redesign a huddle space to an open, collaborative, and innovative space. Updated furniture to a more modern and comfortable aesthetic. The space included three meeting tables, paired programming stations, standing tables, and soft seating. New technology includes three Microsoft Surface Hubs, rolling TVs, one cord plug and play paired programming with two monitors, and a test of a Microsoft Surface Studio.

Draw Together

Worked in a team of two to make a mobile application that allowed one or more devices to share a drawing surface. On separate tablets a user can draw an image or hand write text in various selected colors and the synced tablets would automatically refresh and display that image on it's art board. Technologies used: Xamarin, SkiaSharp, and CosmoDB.

Google Dialogflow

Developed a prototype Google Assistant Agent that allowed a user to get card recommendations based on contextual information provided like holiday, person, or occasion keywords.

Technical Student Assistant: Help technicians with support tickets, maintain inventory, facilitate transfer of equipment between divisions, and deliver and configure equipment.

This Website

The current website you are on is a simple HTML5, CSS3, Bootstrap, and Javascript website. The code has a repository on Github, but the hosting is through Namecheap and Netlify. Netlify is static hosting service that creates a CI/CD pipeline with the Github repo, so anytime I commit a change to master Netlify automatically picks it up, installs the needed NPM packages I specify, applies my specified configurations, and deploys it to a live server that Namecheap routes DNS traffic to.
