Daniel Levitan BE, MSCIS, MCP

Senior Software Engineer / Developer

Key Strengths

Lifelong learner with an engineering view of IT. I utilize and take advantage of new features by establishing similar patterns, quickly diagnose problems, find alternative ways to do things, have the ability to understand what the code is doing, always striving to find improvement in both code and process. Proven track record of going beyond what is being asked, taking on new challenges, and improving the knowledge of those around me.

Specialties: Experienced with Dot Net [Universal Core], the latest version [8+], with experience going back to Dot Net Core version 1.1, as well as Cloud Development. This includes working with different configurations of Blazor, which is similar to Angular and React but uses C# as well as the new Dot Net Core API libraries such as Fast Endpoints and Multithreading. Experience working with both diverse groups and establishing working connections with other teams, including DevOps, Architecture and Security. MCP is based on certification in ASP development.

Career Experience

April 2023 – September 2024 Bank of America

Development Group/Senior Developer - Contract

API Development - Fast Endpoint development using Slice Architecture with Redis and Data Lakes.

Blazor Development – Dot Net Core APIs with Dapper ORM and MVVM Layered Architecture. Development of an existing cloud based application for a Technical Support group with WASM Blazor front end converted from Server. Responsible for Setting up the project architecture that supports Unit and Integration Testing and upgrading the project to Core 6.0 and then to 8.0. This included writing the base classes and establishing proper dependency injection. In addition to the upgrade and Architecture, work on training junior members of the team.

Of note, I was a member of two agile teams at the same time. This enabled me to both function as a Full Stack, using user information from one team in the other for API development. It also allowed me to improve a project that ended up using a Temporal table. This arrangement allowed for improved communication and coordination between the application and api teams. The second tram was focused on updating the APIs for FastEndpoints [MediatoR Pattern and Facade], where I was both testing out the new libraries and implementing new functionality.

Environment: Azure Cloud Application with WASM MVVM Blazor, C#, Visual Studio with Jira DevOps, SQL Server Backend Database Server, Dapper ORM, SeriLog, Mud Blazer Desktop Components, XUnit.

July 2022 – February 2023 Wells Fargo Bank

Development Group/Senior Lead Developer - Contract

Greenfield Development – Dot Net Core APIs with Dapper ORM and Layered Architecture and C# code. Development of a new cloud based application for the Insurance Licencing group with a Blazor front end. Responsible for Setting up the project architecture and brought the team up to speed on both a layered architecture, Core 6.0 and Blazor Webassembly / MVVM. By developing the initial files for both the layers, DI, Models, and Tests, the other developers were able to easily understand how the architecture worked and continue with creating the data layers and the API.

The internal application was to be used by a group for continuously monitoring and processing other employees based on data brought in from an external system. The code we wrote allowed the group to import the files and then process, track and report on the progress. One of my contributions was to write the initial code and unit tests, explained how the code worked to the developers (including delegates), and assisted them with learning the design pattern.

Environment: Azure Cloud Application with WASM Blazor Application, C#, Visual Studio with Jira DevOps, SQL Server Backend Database Server, Dapper ORM, SeriLog, Mud Blazer Desktop Components, XUnit.

September 2021 – May 2022 Caliber Home Loans

Development Group/Senior Developer - Contract

H2O Application – Dot Net Core APIs with EF ORM and Layered CQRS Architecture. Development of new APIs for providing Temporal Table Historical information as part of an Agile team using Azure Development Tools and pipelines. Application uses handler based architecture with Structure Map and Auto-Mapper with SQL Database. The cloud front end is AngularJS and HTML hosted in Azure.

As Entity Framework did not support Temporal Tables, I worked on special coding and stored procedures for providing change details to the GUI. Part of the reason to use the new Architecture was to enable testing. As such I implemented testing of the code I worked on. Most was in C# with some of the older code in VB.

Environment: AWS Cloud with MVC and Angular Application, C#, Visual Studio with Azure DevOps, SQL Server Backend Database Server, EF and Dapper ORM,.

November 2019 – April 2021 CED

Architecture Group/Software Engineer - Contract

MVP/MVVM Application – This is a cutting-edge way of doing Windows Based applications, similar to Web Based MVC applications. Dapper for the Data layer, Auto Mapper, Structure Map, NLog, XUnit testing, and Spire were the main tools that made up the infrastructure along with a significant amount of custom architecture code that made the solution work with an eye to minimizing developer effort and the implementation of unit testing (Clean Architecture). My role was in developing pages that implemented the most difficult aspects of their main application for developers to use as an example, identify any code that was not working, provide ideas for improvement, and develop tools such as Item Templates and Wizards.

Developed example C# code and documentation showing how to use inheritance instead of copy, use of extension methods instead of Library Methods, and how to use messaging instead of events. The Wizard set up the related files in the correct projects and allowed code to be optionally added to the files. Testing examples show both the use of Test Fixtures and Automapper for applying Mocks.

One of the utilities I wrote was for SSRS and printing them as a pdf. The top level page was for a viewer, and the page used inheritance of a base page that had code for pdf processing/conversion.

This project used Infragistic components and work entailed properly configuring the components for providing a consistent look and feel.

The Wizard created all of the files for MVP (View (3 files), View Model, Presenter, and View Interface). As this was a multi project solution, the files with their code were then moved to the correct solutions. The Wizard also provided options that some of the pages might use in the way of optional coding. One of the projects was for APIs with examples that provided the same functionality as the application service.

Several pages that had been developed as coding examples were selected as proof of concept that the largest and most difficult of pages could be converted from the existing framework to the new framework. This entailed reviewing C++ code for the logic on how the page worked and converting it to C# code that was being used for the new project. Communication between the pages used MSMQ that was built into the base classes.

Environment: Windows 10 Desktop Application with programing similar to a WebApplication, C# code, Visual Studio with Azure DevOps, SQL Server Backend Database Server, Dapper ORM, Auto Mapper, Structure Map(DI), NLog, Spire PDF Tool, SSRS, Infragistics Desktop Components, MSMQ
