Enhancements and bug fixes to an angular-based Enterprise system that functions as a web front end for a couple ERP systems. Modified bootstrap navbar items to integrate the quoting system into our system. Added an application pallet for links to external applications. Developed the support classes, interfaces and sevices on the angular side to support these components and the NGRX store layer. Developed tables, procedures and keys on the Sql side. Developed classes, services and WebApi apis to support the application pallet and the dynamic generation of icons base on table data. Analyzed lazy loading of angular modules and responsiveness for the system. TFS was the source control system.

Developed architectural options for them based on angular and Express/nodejs. They wanted to switch from .Net backend to Express, so I figured out how to implement servers with TypeScrypt transpiling, to make it more like what they were used to with Angular on the client. I migrated my prototype code into TypeScript versions of the two back-ends. I made two front-end Angular 7 programs including basic layout, html, css and toolbars and two back-end servers in Express/TypeScript to allow two possible data query and manipulation strategies. I did not have database access so I mocked databases using TypeScript with data I generated by writing a C# program. I also reviewed several of their older .Net C# projects for possible migration to the new architecture. Did a lot of review of existing legacy DotNet code for possible refactoring. TFS was the source control system.

I worked on several projects for the Oklahoma Turnpike Authority. The first one was a proxy program that was needed because a new vendor was awarded the contract to provide license plate look-up data. In order to provide a direct replacement of the existing api, a proxy was created to simplify the change-over. A two way interception of messages was implemented and conversion errors were logged to the corporate logging system.The next system was a public facing web site for receiving Problem Reports from the public. These interactive forms allow the public to report various issues to the Turnpike Authority. This project was done in Angular 7 with DotNetCore a Sql Server on the back-end. I created the tables, keys, stored procedures and services and finished the forms and UI code for entering and saving the data. TFS was the source control system.I also did enhancements on another system that was very old.

Software Engineer III 08/06/2018 to 12/28/2018Developed a critical Angular 6 based application with a C#/Web Api and Sql Server back-end. The client resells data harvested from public records and other sources. They needed a web-based system to manage hundreds to thousands of ETL processes that perform various complex processing, transformation and loading tasks. The system provides a friendly web-based front-end and apis for remotely executing an ETL system called Pentaho Kettle. The code accommodates local and remote api calls for Launching and controlling Kettle job processes. I designed and built the front-end including basic layout, html, css, grid and toolbars, the stored procedures, web apis, angular services and ui components for the entire system, from scratch. I also designed a batch processing system that starts each morning and begins by generating a schedule for the day and then runs continuously until the days items have all been launched. LINQ queries were used to sort and filter schedule items. Added smoothing to the scheduler to space out conflicting schedule entries. TFS was the source control system.

Training: Break taken to concentrate on angular 2+ and related front-end development technologies. This took a little longer than expected because of the massive differences and the large number of dependency for an application. Reviewed design aspects related to use of TypeScript instead of JavaScript. Took off additional time for various reasons.

Worked on various activities to assist final setup of a new, very large, multiple project system about to go into test. Worked on setup of TFS 2017 build and Octopus Deploy processes for projects migrated to TFS 2017. Modified projects for deployment by Octopus Deploy and the internal package management server.

Developed a central user access request system for getting new accounts or modifying existing accounts and subscriptions. The technologies include angularJS, Asp.Net WebApi, Sql Server, claims based authorization and stored procedures that enforce security to the user level.

Made enhancements to a single page application and related APIs for a critical customer portal. Modified angularjs and Web API code of existing application to improve security and add features requested by the customer.

Took a break from working to drill down into development areas learned in recent years and practice some new skills.
