Technologies: C#, VB, .NET, SQL, LINQ, TFS, Git, Octopus, Jira, Visual Studio, Crystal Reports, WPF, WinForms, Entity Framework, MVVM, DDD
Director of Software Architecture and Development for Treasury Services Business 2010-present
  • Architected a new C#/WPF application to replace three VB/WinForm applications created in the early 2000s.
    • Written as a desktop application to provide the best experience for data entry.
    • Utilized DDD and MVVM design patterns to ensure the code is modular, readable, maintainable and extensible.
    • Organized core “plumbing” into base classes and extensions then created Visual Studio templates to simplify development for junior developers.
    • New application initially hosted the WinForms from the original applications to provide a seamless transition for the users and avoid supporting multiple applications.
    • Developed an inter-application notification system utilizing RabbitMQ. A window in the new app displays notifications for completed reports and actionable changes such as new trades. This helps users work more connected as if they were in the office.
    • Built-in a document system using a rich text editor so that users can write documentation for each page in the application.
    • Added user preferences to customize the application and choose favorite reports for quick access.
    • Developed solutions to missing features in WPF such as:
      • the ability to have more than one database table in an editable GridControl.
      • moving data validation from the ViewModel to the Repository to maintain separation of concerns.
      • an XAML extension to overlay two icons for buttons.
  • Architected a new report system:
    • Interfaces enforce that each report is defined by a single class containing all knowledge about the report including user parameters, database query and layout.
    • Communication with the main application is by messages to maintain separation.
    • WPF controls for report parameters are programatically generated based on parameters each report requires.
    • Allow for multiple report types such as Crystal Reports and Excel.
    • Run reports in the background.
  • Developed an automated build, test and deployment processes to streamline our workflow and avoid process errors during production deployments.
  • Created a Blue/Green deployment process and an application to load the Blue or Green version of the application. This allowed us to deploy changes the business needed during business hours when all resources are available.
  • Eliminated production issues by performing strict code checks for indeterminate and fragile code.
  • Developed a program to inventory the stored procedures used in our 140+ Crystal reports to know which reports were affected by database changes.
  • Developed a program to list the hierarchal relationships between SQL stored procedures, functions and views. This tool illuminated which reports would be affected by a change in a low-level database function.
  • Developed a program to test our reports to ensure changes to the database didn’t affect user reports. This test automation saved hours of manual work.
  • Moved the database into a Visual Studio database project and fixed hundreds of issues preventing the project from building. Database changes now follow the same versioning and deployment process as the code.
  • Cleaned up the database by removing hundreds of unused functions, stored procedures, views, triggers, tables, etc. which had accumulated over a decade. With only relevant database objects remaining, our understanding and ability to refactor the database increased.
  • Combined two databases into one to eliminated a significant amount of SQL code and improve performance due to the elimination of cross database queries.
  • Performed several major refactorings of the database schema and data to align with changes in business practices.
  • Fostered a symbiotic relationship with the Managing Director of Operations to analyze the data using business rules and present anomalies to data owners for correction.
TFS Administrator 2010-2019:
  • Orchestrated software and hardware upgrades.
  • Added, merged and diverged TFS collections and projects.
  • Maintained system and user security by utilizing my TFS administrative tool which lists user permissions in all collections.
  • Provided user training and assistance
  • Fostered an Agile development process by introducing Git and creating Kanban boards.
  • Developed a TFS build task tool [Set Assembly Version] to facilitate tracking of software changes from source code to executable.
  • Developed a corporate wide deployment tool [Patchman]. Features include:
    • A plugin architecture using the Factory pattern makes the addition of new functionality (tasks) as simple as creating a new class.
    • An XML based scripting language syntax similar to MSBuild and NAnt to make more complex deployment processes possible.
    • Detailed deployment per auditor requirements.
    • Detailed error information to indicate source of failure and simplify debugging.
    • Fully documented user manual with examples.
Octopus Administrator 2017:
  • Installed, configured and demoed deployment process for corporate wide use.
  • Helped users with setting up their projects and installing tentacles.
  • Modified Patchman into an Octopus step template.
Jira Administrator 2016-2017:
  • Installed, configured and administered users.
  • Oversaw migration of data from Gemini system.
  • Created a process within Jira for users to approve changes and a report showing who performed the approvals. This made it easy for auditors to verify the software development process was followed and met their approval as proof of Statement on Standards for Attestation Engagements (SSAE) No. 16, Reporting on Controls at a Service Organization.

Lead Deployment Engineer
  • Configured and deployed large-scale web applications to a Windows server farm.
  • Saved the company thousands of dollars per deployment. My first deployment was a 48-hour marathon beginning Friday evening. 90 people rotated on site.  20 hotel rooms were purchased for naps between shifts.  In contrast, my last and largest deployment was an 18-hour event starting Friday evening with a staff of 30, some on site and some remote.  No hotels were needed.  No incidents occurred and the deployment was declared a success on noon Saturday.  After my first deploy experience, my goal was to tackle the complicated and error prone deployment practices.
  • Created NAnt scripts to automate and enhance robustness of the build and deployment process.
    • Added error handling to recover from non-fatal problems such as creating missing directories.
    • Performed system testing to detect potential server configuration issues such as testing network connections and testing for required components like .NET.
    • Verified production passwords against LDAP prior to the start of deployment thus potentially avoiding hours of re-deployment.
    • Eliminated manual steps.
  • Built a GUI to call deployment scripts.
    • The GUI is configured via a built-in XML document. This interface was adapted to new applications by other teams.
    • GUI presented different deployment options based on DEV, UAT, and PROD environments.
    • GUI eliminated errors from constructing complicated command line parameters in the command window.
    • The simple interface made it easy for production administrators and new hires to perform deploys with little training.
  • Developed custom NAnt and MSBuild tasks using C#.
  • Excel runbooks were used to keep track of each step of the multi-department deployment process. I created VBA macros to automate and validate changes made to the worksheet. The goal was to avoid mistakes while performing overnight deployments.
  • Mentored co-workers in technologies and application architecture.
  • Researched and debugged application failures, performance bottlenecks, and memory consumption. These activities were not part of the deployment team job description but my engineer inquisitiveness sparked my curiosity.
    • Uncovered problems plaguing the performance and reliability of the applications such as remoting exceptions, zombie services, memory leaks and network slowness.
    • Provided solutions to application architects, developers and support teams.
