Hello!
I'm Cory Streiff, an engineer turned fullstack software developer based in Berlin, with a focus on building scalable, performant, and reliable applications.
You can reach me at c.streiff@pm.me or let’s connect on LinkedIn.
Background
I graduated from Georgia Institute of Technology with a degree in Material Science & Engineering. I worked in that field for six years, first at an R&D startup making ceramic body armor and then at a materials consultancy in New York, working with designers and engineers at Fortune 500 companies.
But after having designed and engineered physical products, I decided to transition to engineering digital products—pursuing a longtime interest in computer science.
Most recently, I've been working at a software house, where I helped build a Learning Management System (LMS) from the ground up using Ruby on Rails, Grape, and Postgres.
