Summary
Irae Costa is a Senior Backend Developer based in Berlin with 12 years building resilient Django and Python systems for startups and scale-ups. They translate business requirements into maintainable, production-grade services, having shipped complex microservices for e-commerce fulfillment and data-driven municipal insights. As a pragmatic entrepreneur and former CTO/co-founder, Irae has hands-on experience designing fault-tolerant payment and order services that scaled into standalone companies. Their personal projects reveal a penchant for efficient, low-cost engineering—counter.dev processes traffic for 500 active sites on a tiny VPS for five years—and low-level systems work like a lightweight container platform written in C. Comfortable across the stack, Irae pairs operational thrift with an emphasis on security, determinism and developer experience when building AI-assisted tooling and workflows. Colleagues consistently praise their ability to deliver robust, high-quality software and to mentor junior engineers.
