I’m Matias Cazas, a senior backend/full-stack software engineer based in Córdoba, Argentina, with 6+ years of experience building and owning SaaS products end-to-end. I specialize in designing production-ready APIs and backend systems, leading data-backed workflows, and turning business requirements into reliable software. I’ve been a technical lead for a small team, taking responsibility for architecture, delivery, production operations, and process automation. Recently, I built a GPT-powered candidate intake flow that dramatically reduced manual processing time, expanded a recruiting SaaS platform across multiple countries with localized business logic, and implemented fast Elasticsearch search for multi-criteria candidate discovery.…I’m Matias Cazas, a senior backend/full-stack software engineer based in Córdoba, Argentina, with 6+ years of experience building and owning SaaS products end-to-end.
