Gustavo Grieco SL

We help early-stage startups turn MVPs into production-ready products. Our team has hands-on experience in the startup environment: we've built payment integrations, user-facing platforms, and backend systems under tight timelines and budgets. We work as your external dev team. You focus on product-market fit, we handle architecture decisions, clean code, and reliable deployments. Stack: React, Node.js, Python/Django. From a rough prototype to a product your first paying customers can trust.

We build browser-based games from concept to deployment: playable, polished, and ready for your audience. Our specialty: games with procedurally generated content (puzzles, levels, challenges) that keep players coming back because no two sessions are the same. Ideal for educational platforms, marketing campaigns, or standalone entertainment products. We handle the full stack: game logic, UI, backend, and deployment.

Custom web applications built to solve specific business problems: client portals, internal dashboards, booking systems, invoicing tools, and workflow automation. We don't use templates or page builders. Every application is coded from scratch to match your exact process, not the other way around. Our stack (React, Node.js, Django) means fast load times, responsive design, and easy integration with the tools you already use, from payment processors to CRMs. We build, deploy, and support. You own the code.
