Santiago Duran Ruiz

I help companies build intelligent digital products that generate real results — from complete web applications to AI automation systems.

I am Co-founder and Software Engineer at Zentra, a tech consulting startup where we design AI-powered solutions that analyze business data, predict trends, and generate actionable improvement plans. This has given me a complete view of the product lifecycle: from technical architecture to business impact.

What I can bring to your project:

→ Full Stack Development: React, Next.js, Node.js, Python, TypeScript. Fast, scalable, and well-designed applications.

→ AI Integration: Multi-agent systems, intelligent automation with LangChain, OpenAI API, RAG, and autonomous agents. I don't just implement AI — I connect it to real business goals.

→ Cloud & DevOps: Deployment on AWS, Docker, CI/CD with GitHub Actions. Production-ready infrastructure from day one.

→ Design and Architecture: UX/UI design in Figma, microservices architecture, Clean Architecture, and robust APIs.

I have worked with businesses of all sizes creating everything from WhatsApp sales virtual assistants to automated AI phone reception systems, analytical dashboards, and websites for local businesses.
