2022 - 2024: Dev Manager* for eSeal - replacement system for our electronic engineering design sealing work process using CAD UI to view, edit, and annotate documents, certify documents, manage user settings and compute billing for services.- Implemented with C# web API's using REST and SOAP (for backwards compatibility)- Front end designed with Angular and using ngrx to preserve state- hosted in docker containers within Azure, prototyped with Dapr.2016 - 2024: Dev Manager* for Infrastructure Team - owned and developed APIs/projects utilized by other various teams- Re-implemented and released Mobile Viewer iOS app given a skeletal prototype. Utilized the iPhone's GPU to render infinitely scalable text rendering to avoid artifacting when viewing text in the CAD display.- migrated API's from our desktop suite to NuGet for wider company distribution- Developed Materials application used by MiTek's desktop Sapphire Suite- Developed and maintained several APIs, developer utilities, and web hosted services- Posted job requirements, formulated in person interview scripts, interviewed candidates, and hired candidates for full time employment and summer internships- Performed yearly reviews and mentored team members regarding yearly goals and performance- Set up sprint planning cadences and rituals- Performed Scrum Master responsibilities (aglie inspired)2010 - 2016: Software Engineer III on Infrastructure Team- Simplified and refactored MiTek's in-house object cache API- Refactored and completely redesigned MiTek's sprawling unit conversion API (created a configuration language in xml to extend functionality rather than through code changes)- Designed and developed an incredibly flexible API top dynamically retrieve property and property related meta information off of objects to interface with .NET Framework PropertyGrids, without resorting to object hierarchy or base classes.*Dev Manager responsibilities were 50% development and 50% managerial.

* Development, testing, and release of feature upgrades to Order Management servers in high impact environments (C++, Java)* Primary liaison between the Private Wealth Management and Futures Sales Technology Teams and the Order Management Team* Extension and maintenance of internal online order history system (C# & .NET technology)* Design and implementation of database purging and archiving scripts (Perl)* Optimization of SQL queries and stored procedures* Contributing to a large collaborative code repository managed with CVS* Multi-platform development for Windows and Linux* Internal support, including day, night, and weekend support services* Problem solving, general system maintenance, and multiple tasks requiring understanding, modification, and extension of legacy code in C++, C#, Java, and Perl without documentation

• Conceived and prototyped MINERVA, an extensive multi-visualization environment for the analysis and comprehension of patients’ medical records, using C# and open source C++ libraries - designed with a dll-plugin architecture, with support for both managed and unmanaged extensions - linked user navigation with information visualization• C++/C# developer/consultant for the NU Radiology Department’s open source research and diagnostic DICOM workstation - added capability to annotate images and export/import annotations with XML - integration and debugging of DCL and DOME libraries - assisted with architectural design in incorporating 3D Slicer, an NIH funded open source medical visualization environment• Developed testing software for a NIH grant concerning the effect of monitor resolution upon radiological diagnosis• Prototyped a Visual Studio Plugin to monitor user’s programming techniques using the Visual Studio SDK

• Augmented a model to simulate urban land using NetLogo, an agent-based simulation and learning environment - visualized results using SimCity 2000 and 3D printed models - extended NetLogo’s programming interface to support multiple model source files and added new functional primitives• Refined a top-down silhouette detection algorithm, implemented in C++ and the STL• Built a CAVE (Cave Automatic Virtual Environment) and multi-projector Tile Display using Chromium and OpenGL• Authored communication software for a passive detecting chess board over COMM ports• Taught students basics of programming in C/C++, data structures, and computer graphics (intro and gaming) one-on-one and in review sessions

(worked summers and during the school year as work study)• Wrote 2D and 3D vector/matrix math libraries in C++ for a surgical system• Authored communication software to an infrared camera over COMM ports• Tested a surgical system for quality compliance (hardware and software)
