My work

Spitfire Management, LLC and CECO Construction wanted to bring their existing project management service to iPad and iPhone. I developed the mobile app to integrate with their existing API and MS Entra, customized to meet CECO’s requirements. The finished app allows file sharing, PDF and image viewing, photo upload, task collaboration, mapping, contacts, phone and email integration, mass file download, and even offline document creation with automatic synchronization.

TS-CHEM is a cross-platform application that was created for McLane Environmental, LLC using Xojo for Windows and Mac. It is a state-of-the-art chemical solute and contaminant analysis tool featuring 32 widely used analysis models, graphing, real-world satellite mapping, 3D export and more. For this application I worked closely with Dr. Charles McLane, incorporating the latest science, and developing industry-first techniques for comparing multiple chemical contaminant plumes in a single view. As such, it is one of the applications that I am most proud of, and I think of it as an exemplar of my work. Read the full case study.

TS-CHEM Activation is an automated solution for delivering activation codes to users after they purchase TS-CHEM. Using NextJS, FaunaDB and Vercel, the application listens for purchase notifications. It then stores that information in FaunaDB and sends an automated email to the purchaser via SendGrid. The purchaser can click a link in the email and enter the System ID found in TS-CHEM. Then, an activation file is cryptographically generated and emailed to the user as an attachment. Once they open the attached file in TS-CHEM their software is activated for a 1 year period.

Scanned Inc. develop a line of portable document scanners called Doxie. Their scanners work with companion desktop scanning software made in Xojo by their in-house developers.

They received new USB scanner drivers for macOS (dylib) and Windows (DLL), and had a requirement to use those drivers from within their existing Xojo application. My job started as simply interfacing Xojo with those drivers using declares and structures, but eventually evolved into developing proof-of-concepts features. Some example are detecting hardware, scanner capabilities, read/write settings, set scan parameters, scanning, printing raw data and compressed images, detecting button presses, and developing more in-depth features like allowing multiple scan-frame selections on flatbed scaners and creating driver testing environments for the team to use internally.

This project is ongoing and many project details are confidential, so I have deliberately avoided showing screenshots of any actual software or API documentation.

When Jay Williamson approached me for a meeting at a local Starbucks about possibly developing a health application I was pleased to provide consultation about what technologies would eventually be involved, and even more pleased when, the next year, Jay selected me to complete the task. The web application, HealthPriceCompare.com, is an essential tool for the U.S. public. Anyone can enter their zip code, insurance provider and medical procedure name to compare prices at different hospitals within a given radius, potentially saving thousands of dollars.

Before truly starting on this project I provided some proof of concepts. We needed to ensure we could quickly search and provide geospatial results for healthcare providers in a radius around a zip code. We needed to compile a massive database of publicly available provider and insurance data, and we needed to plug it all into an easy to use google-map enabled website.

I am pleased to say that I was successful in developing all the required technology and algorithms, along with the website itself, and now HealthPriceCompare.com has launched in Texas, soon to be available throughout the U.S.

After completing work on the hardware drivers for Scanned Inc., I developed a software license management system for their Superiorware brand of applications.

Using NextJS, FaunaDB and Vercel I created a system that would allow existing users to enter their email address. If an order exists for that email, they will receive a link via email to access and manage their license codes.

Additionally, I created a backend licence code admin system. Protected with Next JS Iron Session to allow for different admin levels of access, the system allows wildcard search of customer records and license code management.

This work is ongoing, and some information is confidential, so I have deliberately only shown a screenshot of the main customer-facing license activation page.

CalorieGoals was developed with Cordova and Javascript. It communicates with the USDA nutrition database, as well as custom exercise databases, to allow users to track their food, calories, nutrition, exercise, and take selfies over time that show their progress. Users can also enter custom foods and share them with the community via the cloud, automatically showing up when other users search for the same food. Options like combining foods into recipes, snapping a reminder photo of your meal, and a list of frequently eaten foods allow for easy food logging.

The CalorieGoals Cloud is a database system that allows users to search the USDA food database, an exercise database of metabolic rates (MET), and custom foods and exercises data. To achieve this I reformatted the USDA data used it to create a new MySQL database. This is a very large data set, so I designed a search function that starts with the least processor-intensive search, only moving to more intensive search techniques if an adequate number of results has not been found. For both food and exercises, methods were created for users to add custom items which would become available for other users to search and use.

Crazy Coloring Book was created in Xojo for Windows and Mac OS X. It uses a large collection of line drawings and some intensive algorithms to find the edges of drawings, allowing almost any picture to be colored. Users can also use stamps and have the app play music while they work. This app was intended for kids but found quite a large adult audience. Despite its childish appearance there was some sophisticated graphics programming required for this app.

Dynamic Purchase is a Xojo Web App created by Dynamic AS in Norway to assist with proposal comparison and selection. When their lead developer left, they approached me about taking over development and maintenance responsibilities. This involved fixing some existing bugs, and migrating the application to Xojo Cloud hosting to save the company significant hosting fees. Working internationally with the team at Dynamic AS, and ensuring that Dynamic Purchase works properly in both English and Norwegian, has been an outstanding experience. Because this is an ongoing project, and the information contained in the application is confidential, I have used screenshots taken from the Dynamic Purchase website instead of actual applicaiton screenshots.

Easy Flie Hider was created with Xojo for Windows and Mac OS X. It has several different options for hiding files from the operating system by marking them as hidden, renaming them, and moving them to a secure location that is not indexed by the OS. Because Mac OS X uses sandboxing, this entails creating Security Scoped Bookbarks which allows the app to work with files outside of the sandbox. The app can quickly hide or show files using hotkeys for easy access.

Passwords are particularly sensitive, so to accomplish the goal of allowing users to synchronize passwords over the internet I knew I had to create a “blind” cloud server that could not see any unencrypted user data. Using ASP for device to database communication, and JSON for data formatting, I created a MySQL database that works entirely with encrypted data. All encryption is done on the user’s device, never sharing their encryption key, before being stored anonymously in the database. When the user downloads the encrypted data to a device with their key installed it is decrypted and displayed on their device. That means that no one, not even me or my hosting company, can access any user passwords.

FileCapsule is a cross-platform application created in Xojo that allows users to securely transfer files. A proprietary file-format called a canister (.cnstr) was developed to encapsulate both encrypted data and unencrypted recipeient information. 1024-bit public and private key encryption is used for the utmost security. Development also included PHP and database work to store user’s public keys and contact information, allowing users to create canister files that can only be decrypted by particular recipients.

IP Notification was created with Xojo for Windows and Mac OS X. It constantly monitors the computer’s internal IP address by polling the network adapter, and monitors the wide area network’s external address by querying a script hosted on my website which returns the remote host address. When a change is detected, the application can notify the user by composing an email which is sent either through my servers, presets for Gmail and other popular servers, or through a custom email server. It can also send data to a user’s website via querystring (for storing in a database or sending other types of notifications) or launch an external application with the IP address sent as a querystring.

After completing the MRC Inventory system, which allowed mobile, desktop and web access to a plastic inventory system using barcode scanning, I was hired to make a similar system that followed that inventory through the mixing, testing, storage and shipping process. This required an overview of all product coming from silos, through different states of blending and testing, loading into warehouses and eventual shipment. The system includes detailed reports and a date based warning system to keep all deliveries timely.

When Peter Fichter approached me with his idea for an aviation saftey app, which allowed pilots to easily move through a checklist of flight precautions with details about what the proper procedures are, and why they are important, I knew it was a great fit for Xojo.

Peter knew that he wanted the end product to be used on iPads in landscape mode, and that he wanted a Mac application which would allow him to edit a heirarchial list of aviation safety checklists and import procedural documents. This backend Mac app allows Peter to enter multiple checkists with image and PDF attachments that is fed into the mobile app before compilation. The iPad app reads the database that was exported from this Mac app, arranges all data in the proper form, and allows the user to easily navigate through important safety information all while remaining offline.
