Work Experience

President | Contractor | Indie App Developer

  • Worked for, LLC, the umbrella corporation for my independent application development and software contracts.
  • Served as project lead on an 18-month application rewrite for a system bringing in $30 million/year in revenue. The new architecture moved to an Azure cloud-hosted, with a multi-tenant MongoDB datastore and .NET Core MVC (REST API) microservice-based application stack, utilizing an Angular 6 and TypeScript-powered client from a legacy stack of 1500 single-tenant SQL Server instances hosted in a single datacenter with a Silverlight (and CSLA) powered client. Mr. Bailey worked closely with product management to define strategy, make tech stack decisions, create the backlog (from the feature and milestone macro to Scrum story micro), and to set development priorities for four teams of developers. Mr. Bailey was a key hands-on contributor as well, coding about 50% of each working day to demonstrate best practices, review new code, and to complete complex tasks.
  • Soley developed a direct-sales commercial application called MarkUpDown, the most thoughtful Markdown editor for professionals on Windows 10. It is a Universal Windows Platform (UWP) app written in C# with server support in Node.js. MarkUpDown's marketing website can be found here and the app is available for purchase from the Windows Store.
  • Contracted and consulted on several projects for; including the creation of a .NET MVC system to handle asset management for customer-facing (snail) mail services for major Fortune 500 companies at one of the US's largest mail distribution companies.
  • Worked with a small healthcare practice management SaaS focused primarily on creating a site-wide, customized, HIPAA-compliant chat service for providing site support and provider-patient communication. Leveraged XMPP and Strophe providers that were wrapped with a custom .NET Web API framework. The client code was created with React, JSX, Babel, and a home-grown routing system.
  • Worked with the Hands of Christ nonprofit to fairly distribute clothes, school supplies, and other resources to grammar and middle-school aged tri-county students (Xamarin on iOS experience).
  • Eagerly performed follow-on work at the Navy Enterprise Data Center (NEDC) from the previous position (see below) to keep the NEDC's PowerShell and PowerCLI lights on after ESN's onsite contract expired.
  • Made open-source contributions during this time including TagifyJS (a single-file, zero dependencies, plain JavaScript tag UI library that's easy to use) and SqlDbSharp (an open-source, C#-native relational database management system) written in his spare time. The work is managed in Git via Bitbucket and GitHub, and TFS is used for some contracting positions.

Senior Programmer

2014 - 2015
Engineering Services Network
  • Worked in an onsite contracting position at a navy enterprise data center requiring secret clearance; the work began with updating the legacy VMware Cops reporting PowerShell scripts delivered under another contract and help coordinate the optimization of VMware resources and EMC VNX storage.
  • Wrote scripts to manage complex data diff and update uses, the automation of VMware utilization metrics, in-stream review, and code repair which were all delivered to NEDC Engineering from other contracting sources, and update of all PowerCLI scripts to 5.5 compliance.
  • Acted as the sole onsite, full-time programmer at SPAWAR LANT NEDC.

Senior Software Developer | Team Lead

2012 - 2014
  • Led one of the five agile scrum teams working on PeopleMatter's schedule module which was an online schedule maker, manager, and communicator. The PeopleMatter stack included fairly strict Microsoft MVC 4.0 with Microsoft SQL Server 2008 R2 on the server, and an exceptionally data-rich Knockout.js-powered client.
  • Developed, in a team, PeopleMatter's schedule component which made employee schedules for those mainly in the hourly service/restaurant positions, integrated the employee background check service with products from Sterling Infosystems, and created a JSLint-powered Team Foundation Server (TFS) build policy to ensure that all JavaScript code deposited into the PeopleMatter repository is (reasonably) well-formatted.
  • Acted as the sole coder for two features, the save-for-later status and the reasons-for-applicant status changes; was featured on the PeopleMatter Spring 2014 product release page.
  • Revitalized the new flagship SaaS app called Schedule—which had been near release but didn’t test well on Internet Explorer 6 for a major client—by initiating two sprints with a designer and implemented a custom defensive fix that could be completely turned off by changing one boolean in the client-side code. This client-only, minimal risk fix enabled Schedule's release to logo clients just a few weeks before decisions were made on another—and, with the release, successful—funding round for the company.

  • Designed and created exceptionally advanced, user-facing geo/database query tools—allowing common access card (CAC) authenticated end-users to visually construct and save ad-hoc queries of what amounted to complex SQL joins. These joined data sources, cutting across any number of tables, could then be concurrently queried by data values and geospatial constraints. Other tasks included creating a range query tool (RQT) that allows Army support personnel to quickly find firing ranges by munition or weapon type or by querying a number of other range characteristics.
  • Developed Army Mapper 3.0 using MapFish, OpenLayers, and MapServer to interface with spatially aware and flat data in Oracle and ESRI ArcSDE; it also uses in PL/SQL, C#, JavaScript, and Ext JS.

UTF-8 Code
A code presenting a solution to the StackOverflow question asking for instructions on how to cut a UTF-8 string to a specific byte length. Though seemingly a niche task, it required understanding raw byte work, text encodings, the importance of testing, LINQ and its limitations, and—most importantly—problem-solving with a commitment to performance and efficiency.

The solution can immediately jump within six bytes of the final cut location. Its explanation is also straightforward and clear-cut. The previous answer used LINQ's takeWhile, creating a new string with a substring and remeasuring each time—for each byte—in the string until the requested length was reached. That system was massively inefficient.

PeopleMatter: Schedule

PeopleMatter was a SaaS solution for hiring, training, and scheduling applicants and employees who work in the services sector.

Work for PeopleMatter focused on two pieces:
1) Schedule, the module that creates schedules for employees and different stores, and maintains a running count of their hours worked and costs to staff.
2) Hire, where applicants to companies are tracked, interviews scheduled, and onboarding tasks (I-9 forms, workforce eligibility, training) can be managed.

Schedule work was done using .NET MVC with C#, SQL Server via NHibernate on the back-end and Knockout.js templating for the client. It initially was a seven-team project that leaned exceptionally forcefully on maximizing data on the client's browser and contained complex JavaScript view models bound to Knockout.js templates. The work centered largely on client validation—ensuring the proper translation of business rules from server to client code, speed optimization, memory management, AJAX interactions with server controller actions, and data serialization.

Army Mapper

I worked on a development 1 task for Army Mapper 3.0, the US army's enterprise geographic information system (GIS). It is used for a number of functions, including reviewing the utilization of real property (buildings, roads, parking lots) and other infrastructures on U.S. army bases. Army Mapper is used by the Office of the Assistant Chief of Staff for Installation Management (OACSIM) as a tool to visualize the current state of the army's resource management across army installations (bases) worldwide.

Army Mapper 3.0 employed MapFish and MapServer to interface with spatially aware and flat data in Oracle and ESRI ArcSDE. The work was done in PL/SQL, C#, JavaScript, and Ext JS.
