Software developer and technical project lead — full-stack web, e-commerce platforms, and native macOS apps. I take digital products from requirements and UX through implementation, integrations, testing, and deployment.
Co-founded and ran Lumios Digital (2023–2026), a small studio that shipped 50+ production sites and products for international clients — most of the repos here are that work. Currently available for freelance or full-time roles, remote from San Juan, Argentina.
