Matias – React, AI-assisted coding, Node.js
Matias is an experienced full-stack developer with nearly two decades of hands-on experience across PHP, JavaScript, Vue, React, and Node.js, bringing a rare combination of technical breadth and real-world business acumen. He co-founded and built a startup from the ground up over five years, which gave him strong intuition for translating technical decisions into business value — making him a natural fit for client-facing or product-focused environments. He demonstrates solid practical knowledge of databases, async JavaScript, and React/TypeScript, thinking in terms of component contracts and types from the start. Matias is a reliable, business-minded generalist who works well with non-technical stakeholders and adapts quickly to new challenges.
