Thomas Pregenzer
Software Engineer at Amazon
About
I'm a software engineer at Amazon in Seattle, working on Rufus — a generative AI shopping assistant. My background spans Java, Swift, Objective-C, TypeScript, Python, React, AWS and everything in between.
Now
Recently moved from London to Seattle and exploring new technologies across AI, mobile, and fullstack development. Outside of work, I recharge in the mountains — skiing in winter, hiking in summer, and occasionally regretting not stretching enough. Conveniently, they're a lot closer now.
Yes, I actually spend time in the mountains ⛰️
