Said Echarrouti is a pragmatic senior software engineer with 11 years of experience building end-to-end web applications and backend systems, now based in Fuenlabrada, Spain. He consistently owns architectural decisions and has optimized large-scale data and payment flows—e.g., inserting 1.5M discount records in under 30 minutes and cutting bulk inserts from hours to minutes. Comfortable across the stack, Said has delivered B2B/B2C payment systems, internal APIs, observability improvements and a TypeScript migration, while also shaping team practices like DDD and ADRs. He contributes to notable open-source projects such as Mattermost (billing/subscription UX and backend flows) and expanded validation tooling in valibot, reflecting a balance of product-focused UX work and rigorous backend engineering. Colleagues rely on him for improving developer experience—CI/linting gains, test automation and reproducible dev environments—so teams ship faster with fewer regressions.
