Simone Costa
PERSONAL PROFILE
Full-stack developer with 15+ years of experience across delivery and strategy: development, consulting, project management, and co-founding. I naturally switch between product decisions and hands-on execution, from problem framing to production. Backend Node.js/Python, frontend Next.js/React, and AI integration for automation, search, and data management. I’m strong at choosing what to integrate (and what to avoid) based on impact, timelines, and quality—building pragmatic, reliable solutions. Requirements and technical planning, day-to-day coordination, and clear communication with non-technical counterparts: I turn goals into roadmaps and implementation choices, keeping business and product aligned.
