Software Development Portfolio for Timothy Graf

Once aerospace engineer, turned software developer, polyglot, life long learner, strive to improve my craft, and to be a positive influence on those around me.

I hope to continue to grow as a professional, continue to learn new technologies, and improve my craft as a professional software developer. I have a passion for technology and strive to be a positive influence for the people that I work with and I hope to be able to share and provide my expertise and knowledge from my experiences as a software developer and professional.

I've worked in numerous industries and with many languages and frameworks. I believe the most important goal for a software developer is to produce functional features that users find useful. Working software is the primary measure of progress. I try not to get too caught up in a given language or framework. I view them as tools to get a job done and some tools are better equipped for certain jobs than others.

I consider myself to be a very pragmatic software developer but I do believe in writing clean code and only creating abstractions when there is a clear need for them.

Some of the languages and frameworks I have worked with are listed below and some sample projects are on my GitHub.

Python, Jupyter Notebooks, Pandas, Numpy
Python and FastAPI
C# and .Net Core
Python and Django REST framework
Elixir and Phoenix
Go
JavaScript and TypeScript, React/Redux, AngularJS, Angular, Vue, NetsJS, Node and Express
Scala and Akka HTTP and the Play framework
Java Servlets, XML RPC, JSP
ANSI C on Solaris
C++
Visual Basic
Matlab
FORTRAN

Some of my favorite books are listed below.
