• Provided leadership and development in a medium-sized team for the transformation of monolithic tax reporting into a robust microservice architecture, converting monolithic WCF (.NET) services to RESTful APIs (.NET Core) deployed into Docker containers on a load balanced system with multiple clusters. Using CI/CD best practices using TeamCity, uDeploy to Docker.• Designed and led the team for the migration of the MVC UI to an Angular-developed UI behind SiteMinder.• Ensured these microservice APIs were effectively written with redundancy and scalability in mind so they could be integrated into several other shared applications with partner reporting systems with a focus on disaster recovery capabilities.• Led the vulnerability assessment meetings and its resolutions with internal and external vulnerability assessment groups.• Led and developed the segmentation of each application into approximately 20 main business functions, implementing them as layered microservices using C# .NET Core including initial design• Developed and directed the adoption of container-based solutions using .NET Core, Docker, and OpenShift, a pioneering move for the team that significantly enhanced system scalability and reusability.

• Developed and architected C# applications for a Global Transaction Reporting n-tier reporting engine, using Xamarin, MVC, WCF, calling Microsoft SQL Server using Entity Framework 6.x. Reports were created in SSRS and later migrated to Power BI which I built WebAPI services in C# to connect and run these reports and send back to the Angular Client.• Designed and developed design, and coding, implementing a 100% session-less/SOA architecture.• Created data consumer and producers using IBM MQ messaging services for sending and receiving transactions and acknowledgment messages. This was using the Java WMQ libraries.• Utilized MVVM practices for Silverlight application, and LINQ to SQL for database access and configuration.• Focused on reusability of the main core DLL for integration across multiple projects, enhancing flexibility and scalability.• Employed Agile/Scrum methodologies for project management.

• Led the development and architecture of the main billing and payments area for the Florida State Health Care Project, using ASP.NET 4.0 for web functionality, along with supporting WinForms and WPF applications.• Implemented multi-core parallel processing techniques available in .NET 4.0 to enhance application performance.• Oversaw the architecture, design, and coding of the project, ensuring a 100% sessionless/SOA architecture using WCF for efficient communication between the website and database.• Developed the WPF application adhering to MVVM practices for maintainable and scalable code.• Managed database access and application configuration using LINQ to SQL and LINQ to XML, respectively.• Focused on the reusability of the main core DLL, enabling its use across multiple projects to add a significant level of versatility and flexibility.• Employed Scrum methodology for effective project management and team collaboration.

• Team Lead and Architect for the Motivano SmartSavings employee benefits application, a portal-style platform offering a range of products and services used by fortune 500 companies including Citigroup.• Oversaw the architecture, design, and coding, leading a team to develop the application using ASP.NET and SOA principles, with communication facilitated through WCF.• Designed and implemented various components including a Discount Marketplace, prepaid card site, Single Sign-On (SSO) application, and corporate site, all accessible through the portal.• Developed the application in C#, leveraging the .NET 3.5 framework and ensuring adherence to Object-Oriented methodologies and WCF Web Services.• Focused on multithreading and the integration of LINQ to SQL and Enterprise Library for various aspects of the application.• Emphasized separation of business and data access layers, promoting code reusability across projects.• Collaborated with business stakeholders to define business logic and class structures, aligning technical solutions with business requirements.• Supported Database Administrators (DBAs) in developing LINQ-compatible stored procedures and worked with graphic artists for design feasibility in Visual Studio.• Applied SCRUM and Agile methodologies for project management, ensuring efficiency and adaptability in development processes.

• Developed a Data/Voice Customer Service software for a telephony/cards project, designed to manage calls and provide real-time customer information through screen pops.• Programmed the client application in VB.NET, integrating a .NET Remoting Service written in C# with DevExpress controls for enhanced UI/UX.• Utilized Oracle 9i for the database, implementing XML for data storage via .NET Remoting Services.• Created comprehensive reports using .NET Crystal Reports, extracting and presenting data directly from the application for business analysis and customer service insights.

• Collaborated with The Weather Channel® under the GenCode name to develop a near real-time hurricane tracking client-server application.• Initially developed the client application in Visual C++, later transitioning it to C# for increased speed of development and simpler memory management using Xamarin for the iPhone app and Java for the Android app while still providing excellent performance and functionality.• Facilitated data transmission and retrieval between client and server using XML Web Services.• Utilized ASP for server-side processing, connecting ASP pages to a SQL 2000 database for real-time data access.• Expanded the application's reach to mobile devices by writing parts of the application in WAP, enabling data retrieval on cell phones.Design and Developemnt http://www.gencode.com/microserviceandschema

• Tasked with designing, prototyping, coding, testing, and troubleshooting a new client application using the .NET framework, integrating XML, ADO, Datasets, and threading in Visual Basic.NET with C# components.• Established server connections via sockets using XML, enhancing data communication efficiency.• Significantly contributed to the server development, enabling NASDAQ stock trading, quotes, and portfolio management for the Electronic Communications Network (ECN).• Managed a multi-tier system with server applications developed in Visual C++ and Visual Basic 6.• Implemented transactions through component service packages (COM+), using SQL 7 and initially Oracle 8i databases, both utilizing stored procedures.• Ensured high-speed, high-transaction, and high-volume capabilities to facilitate near real-time NASDAQ data processing, handling millions of shares daily.
