\begin{itemize}
\item
\ressubheading{Subcontractor Supporting AFRL, AFLCMC, and NASIC}{}{Principle Scientist and Software Engineer}{Apr 2014 - Present}
\begin{itemize}
\resitem{\textbf{Software: As-Manufactured Mesh Metamorphism:} Creator and lead developer for \texttt{femorph}, a patent pending revolutionary software that allows finite element model updating to new geometric configurations. This tool is an enabler for the AFRL/RQTI HIT research agenda, AFRL Digital Twin program, and has transitioned to P\&W as an integral software to their manufacturing quality control efforts. This is the first ever DoD software license agreement and \texttt{femorph} includes yearly of license fees in excess of \$150K/yr. See \url{https://www.wpafb.af.mil/News/Article-Display/Article/1503043/afrl-signs-first-of-its-kind-software-license-with-pratt-whitney/}.}
\resitem{\textbf{Software: Automated Traveling Wave Excitation:} Developed software to interface using Python and ctypes to directly control laser position, drive hardware, and collect data for AFRL's Turbine Engine Fatigue Facility TWE. Software bypasses original LabView software to directly control the National Instruments hardware using a Python interface through \texttt{ctypes}. Improved software gives more repeatable results and allows for the automation of batches that would have required hourly manual intervention. Software is regularly used for RQTI traveling wave testing and batch testing times have been reduced from from 5 days to 4 hours while improving accuracy.}
\resitem{\textbf{Research: Strain Energy Super-convergence:} Estimates finite element model (FEM) eigenfrequency convergence using higher order interpolated elements. Enables up to an order of magnitude improvement in frequency convergence at a smaller computational cost than refining a finite element mesh. Software runs without mesh refinement, potentially eliminating the need for a grid convergence study. Research was presented ASME IGTI 2015 and published in 2016. Currently in use at AFRL to evaluate model convergence.}
\resitem{\textbf{Research: Mistuned Blade Tip Timing Limits:} Wrote software that calculates blade tip timing (BTT) limits for engine testing using as-measured geometry. Software evaluates the signal to noise ratio of blade to blade variations in probe measured stress to deflection ratios. Enables user to place BTT spot probes in a more ideal location to improve mode detect-ability. Research was presented at ASME IGTI and is in use in AFRL in conjunction with Gauge Map software. Enables AEDC testing of damped F112s to support a \$1M RQTI effort.}
\resitem{\textbf{Research: Analytical Mistuning Identification:} Using personally developed mesh metamorphosis software, generated a FEM representative of an as-manufactured rotor and verified analytical blade response amplification by correlating the results from traveling wave excitation (TWE). Obtained over 95\% correlation to sector mistuning, and for the first time in experimental research achieved positive correlation between a geometric mistuned model and experimental results. Research presented at several engineering conferences, to include SciTech and ASME IGTI.}
\end{itemize}
\item
\ressubheading{Full-Time Developer at Ansys}{Boulder, CO}{Principal Software Developer}{June 2019 - June 2023}
\begin{itemize}
\resitem{\textbf{Leadership: PyAnsys Project Lead:} Led a talented team of developers at Ansys in creating advanced software interfaces for Ansys products, such as Fluent, MAPDL, and AEDT. Created the PyAnsys team from scratch and rapidly hired or managed the hiring of 8 talented developers. Developed cloud-based software employing \texttt{gRPC} with Protobuf support, Microsoft Azure, Kubernetes, C++, Python, and FORTRAN. This software is now being used within Ansys and at several engineering companies.}
\resitem{\textbf{Software: PyMAPDL:} Pioneered the development of an intuitive Pythonic interface to MAPDL, employing diverse communication protocols including gRPC. This software is now in use by global firms for automating design and solution analysis. Contributed across multiple business units to launch an official, Ansys-supported release of PyMAPDL, now hosted on Ansys's \href{https://github.com/ansys/pymapdl}{GitHub ansys/pymapdl}.}
\resitem{\textbf{Cloud Deployment: Desktop Products on Kubernetes:} Devised an innovative method for deploying stateful services on a stateless platform through the use of micro and macro services. Successfully deployed monolithic desktop applications as stateful Kubernetes services using Docker containers, supported by a variety of microservices, including a state manager acting as a reverse proxy.}
\end{itemize}
\item
\ressubheading{Amazon Seller - Brooke's Book's}{}{Business Owner}{Mar 2009 - Mar 2021}
\begin{itemize}
\resitem{\textbf{Entrepreneurship: Brooke's Books:} Founded and managed an Amazon bookstore specializing in textbook retail arbitrage. Utilized market timing to strategically purchase and sell books. Grew the business to gross nearly \$1,000,000 annually in the final 7 years of operation before selling it in March 2021.}
\resitem{\textbf{Data Analysis & Automation: Amazon Price History API:} Built and maintained a comprehensive database of price and demand history for various Amazon products, which automated the process of identifying ideal buying and selling times and discovering new product opportunities. Later transitioned to \texttt{keepa} for data acquisition, coupled with a cloud-based Python database and auto-pricer on Google Cloud and Microsoft Azure.}
\resitem{\textbf{Leadership & Process Optimization: Remote Contractor Management:} Led and managed a team of fully remote contractors responsible for textbook repackaging over a 6-year period. Streamlined operations by integrating with Amazon's fulfillment workflow and training contractors to independently repackage, bin, store, and ship textbooks. Maintained a custom supply and order database via Python to manage the process efficiently.}

\item
\ressubheading{Captain, United States Air Force}{Wright-Patterson AFB, OH}{Principal Engineer}{Mar 2011 - Apr 2014}
\begin{itemize}
\resitem{Provided analysis of a variety of United States Air Force turbo-mechanical components, both fielded and in development, with an emphasis on stress limits, mistuning, and high cycle fatigue. Developed advanced algorithms to reverse engineer and analyze as manufactured components and their analytical response due to deviation from the designed geometry. Major accomplishments listed below.}
\resitem{\textbf{Automated reverse engineering through optical scanning:} Pioneered an approach to modify an existing finite element model to match the surface geometry from a disorganized point cloud. This enables the automated reverse engineering of a variety of engineering structures through optical scanning. Approach used to recreate a turbine using direct metal laser sintering.}
\resitem{\textbf{Performed IBR reverse engineering using novel approach:} Analyzed a retired cruise missile IBR and calculated blade tip timing limits using as-manufactured geometry without existing CAD or drawings. Determined fleet variability and maximum allowable engine operating conditions using an ANSYS and MATLAB batch written from scratch.}
\resitem{\textbf{Determined root cause of critical part failure:} Tasked by USAF to generated a T-6 control linkage CAD and FEM to determine root cause for failure. Generated CAD using schematics, verified geometry through optical scanning, and identified failure region through robust modeling. Presented USAF with a modified design to eliminate failure region and reinforce structure to eliminate Class A aircraft mishaps.}
