Owner/Principal Software Consultant

Responsibilities:

• Provide consulting services for designing and developing software solutions. This ranges from enterprise domain models using Microsoft technologies like SQL Server, .NET, C#, ASP.NET Core, and WCF to web development using Angular 1/2/4, React, TypeScript, bootstrap, npm as well as mobile app development with Swift for IOS and Java for Android.
• Design and develop a dental imaging system used to store tooth data and images to allow matching through image recognition and machine learning. Front end UI is developed with Reactjs, redux, redux - forms; back end services were developed with Go (Golang); databases utilized were PostgreSQL and Amazon Dynamo; and files are stored in Google Cloud Storage. Web UI is hosted in Amazon AWS and app service is hosted in Google Cloud App Engine. This application is developed to work with Google Cloud Machine Learning to train and provide better matching for image recognition.
• Design and develop a custom lease management system used by a RIET company to manage their lease and building workflow. This was an application designed from the ground up using Angular 4, ASP.NET Web API, and SQL Server. This web application is a responsive application with Bootstrap so it can be used on the desktop, tablet, and phone.
• Telerik’s Kendo UI for Angular was used for web controls. This application integrates with the clients ERP system (MRI) to retrieve specific building and property data.
• Develop custom implementation for Loan Sphere (Empower) for financial institution. Developed a custom component with exports general ledger data from the fees and payoffs from a loan to a CSV file and distributes the file to be picked up by an ERP system for import. Development is in C# integrating within the Empower Framework.
• Beauty Services App: Developed a mobile app, using PhoneGap, that allows customers to request beauty services and located beauty artists available in the area. When an artist accepts the request, the artist would travel to the customer for the requested service. Once complete, a transaction is charged through a payment gateway to the customer. This app was deployed to the Apple App Store and Google Play Store. PhoneGap was used for the mobile app development, ASP.NET Web API was used for the REST Service, and MySQL for the database. We also integrated Twilio for the communication between the customer and artist and Authorize.NET for the payment gateway.
• Construction Service Locator: Designed and develop native mobile apps for Android and IOS for construction companies to request and locate services. Database is developed using SQL Server and is deployed to Azure SQL. The REST web service is developed with ASP.NET Core and is deployed to Azure as an App Service. Client apps for Android and IOS are native apps developed with Java in Android Studio and Swift in Xcode.
• Order Dispatch: Designed and developed a service ordering dispatch system which uses a web based portal for admin management in the office and an Android client app which service field workers use. Web portal allows an admin user to assign and dispatch orders to specific field workers. Notifications and commands are received by the Android device through Google’s GCM service and outbound communication is through a Restful WebAPI back to the server. Backend database is SQL Server, C# business logic, WebAPI for a Restful Service Layer, Angular for the admin portal, and Java in Android Studio for Android Development. Claims Portal: Lead a team to design and develop a claims portal with AngularJS, bootstrap, SignalR, WebAPI, C#, SQL Server, and RabbitMQ. We integrated with an existing application and enhanced the capabilities and workflow according to the client’s business process through a new SPA portal. RabbitMQ was used to subscribe to event messages from the existing application which would use SignarR to push notifications up to the client browser. All business logic and security resided in the middle tier WebAPI layer while AngularJS was used to manage the client side development. Travel Security Notification Dispatching System: Client - NC4. Development for a system that dispatches alert notifications to travelers based on current news and events that may affect the subscribed traveler. I worked on integrating various Travel APIs to be able to run analytics for the user’s flights and destinations. This integration piece was developed in C# .NET with the database being Oracle and Angularjs for the UI client side. I also worked on the main web application to develop a feature that allowed the users to manage their itineraries based on the news and events for their trip. Database used was Oracle, Java J2EE for the backend with Struts for MVC, and Angularjs for the UI.
• Address Standardization: Designed and developed an address standardization service which parses, standardizes, and verifies addresses. This service is exposed through a WCF SOAP endpoint as well as a WebAPI endpoint for a RESTful API. The data access is an inversion of control design which allows for dependency injection of various data stores. Implemented is SQL Server, MongoDB, SQL Lite, and a memory repository. The reason for this design is to allow different types on installs (depending on the environment/hardware/software) and achieving the same output and behavior.

This is a native ios application which communicates through secure RESTful service endpoints provided by the Pasadena IT department. The application is able to work offline, utilize internal storage on the device, and sync back through RESTful services when back online. This involves full cycle software development including gathering requirements, designing workflows, wireframes, UML diagrams, software development, and testing.

Consultant/ Principal Software Engineer

Responsibilities:

• Principal engineer in designing and developing a distributed multi batch processing system for an ETL process for handling an Active Loan process. The system will take new public recording records and apply analytics to existing loan records to determine if a loan is active, paid off, released, etc. The system is developed with SQL Server 2008 as the database, C# for the middle-tier running in a windows service, a WCF service which is an API for commands, and a WPF GUI which consumes the WCF service for managing the process. The system has the ability to process a billion records in 4 hours. This is on one server, running concurrent processes, multithreaded. The design is capable of being distrusted on multiple servers.

This is a data driven web service which allows an admin to manage the user’s product access and geographical access. The service is designed to withstand high load and perform within milliseconds with a database consisting of a billion records.
• Architect and develop a distributed batch processing system. This system intakes batch files, around 100,000 orders, performs a relational bulk import, gets all active worker components, and distributes orders to worker components for concurrent processing. Worker components are windows services which self hosts a wcf service for communication which is consumed by the controller/manager. Worker component itself, is a service oriented architecture consuming multiple services to provide different types of processing for each request. Worker component is designed to behave polymorphically with each service it consumes. Communication between controller/manager to worker is through tcp authenticated with Windows Authentication. The controller/manager is also a self hosted wcf application which has a basichttp and nettcp bindings for clients to consume. With the previous single computer process design we had a throughput of 20 hours for each batch to process. The current architecture processes the batches in an average of 4 hours with 4 worker components.
• System is developed with .NET framework 4.0, C#, WCF, Entity Framework, and SQL Server 2008 R2. Client application, which consumes the controller, is a MVC 3 (Razor) application which utilizes jquery for client side development.
