Software Development Portfolio for Timothy Graf

My journey began in aerospace engineering, but curiosity and a love of solving problems eventually led me to software development, where I’ve found both challenge and joy. I’m passionate about learning new tools and technologies, and I thrive on the opportunity to share what I discover with others. Along the way, I’ve worked across many industries and teams, valuing the different perspectives and practical challenges each has brought.

I believe the heart of software development is building useful, reliable solutions choosing the right tools for the task and focusing on results, not on trends. Clean code and thoughtful design are important to me, but pragmatism and delivering real value come first. I enjoy fostering positive working relationships, and I strive to be the kind of colleague who supports and uplifts others.

Looking ahead, I’m eager to keep growing, both personally and professionally continuing to learn, adapt, and hopefully make a meaningful contribution wherever I go.

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
