Marco Tanzi is a Staff Software Engineer based in Barcelona with 13 years of experience building backend systems for both startups and established companies. He specializes in Ruby on Rails and Elixir, with a strong track record extracting domains from monoliths into modular, auditable services—most recently driving billing and payment platform work including a Stripe migration. Marco pairs hands-on implementation (APIs, billing, search, video processing) with engineering leadership: leading product squads, coordinating cross-team initiatives, and establishing operational processes. He has extensive experience designing scalable AWS-based pipelines and pluggable systems for invoicing and data import, and he emphasizes observability and CI/CD in production. Comfortable in regulated and agile environments, he brings a practical blend of technical depth and cross-functional communication. Colleagues rely on him for turning vague requirements into robust, maintainable platforms that can evolve with the business.
