Portfolio

Expérience professionnelle

Founder & Full Stack Developer

Stocky Argentina • Indépendant

Mar 2025 - Present • 1 yr 2 mos

Built and launched Stocky from scratch — a web app that helps small businesses manage inventory, products, sales, employees, and real-time analytics. The main challenge was designing a system flexible enough for different types of small businesses, while keeping the UI simple and intuitive for non-technical users. I handled the full stack: a scalable backend with Node.js, Express, and MongoDB, and a modern frontend with Next.js, React, and TypeScript. I also integrated AI-powered features including automated business insights and natural-language tools, plus authentication, role-based access control, PDF generation, and automated email workflows. 🔗 Live project: www.tustocky.ar
