Fëanor's Code is a software engineering studio founded by Sergio, an architect with 18+ years of enterprise development experience. We help Spanish and European SMEs deploy intelligent software systems that work entirely within their own infrastructure — without compromising data privacy or regulatory compliance.

Our flagship product, TENGWAR, is a turnkey enterprise RAG platform: hardware and software delivered as a single unit, 100% on-premises, GDPR/LOPD-compliant, and ready to deploy in days. It transforms your company's internal documents into an intelligent knowledge base — giving every team instant, cited answers from PDFs, Word files, spreadsheets, and more, in 100+ languages. No data leaves your network. Ever.

Beyond TENGWAR, we build full-stack web platforms, .NET desktop applications, and custom AI integration pipelines — from private LLM deployments and agentic automation to industrial robotics and production-grade APIs.

Core capabilities:
· Private AI systems: RAG pipelines, LLM deployment, agentic workflows
· Full-stack web: React, Next.js, Blazor, .NET Core, Python
· Desktop software: WPF, .NET MAUI — native Windows & cross-platform
· Integrations: ERPs (Odoo, Dynamics 365 BC, SAP B1), Spanish public data, compliance tooling

Senior-level communication. Practical execution. Solutions built to last.
