Stephan Krug

I am a results-driven Ruby on Rails Software Engineer focused on solving real-world, high-impact problems by building scalable, high-performance applications and leading projects from concept to production. I have owned end-to-end product development—from customer discovery and design to coordination and implementation—launching new revenue streams such as Brazil’s first duplicates product and driving measurable business outcomes.

I collaborate across teams and contribute to architecture and mission-critical features, consolidating data from multiple databases and servers and leveraging tools like Sidekiq, Redis and the Rails ecosystem to deliver responsive, scalable solutions. My background includes backend engineering for B2B cloud infrastructure, contributing to Apache CloudStack and supporting large-scale, high-traffic deployments using Java, Spring and Python.
