We forge robust software for companies that don't bargain with their data.

On-premises AI, custom platforms and mission-critical apps — engineered with the architectural depth of 18 years in enterprise software.

00 / Manifesto
We build software the way you build critical infrastructure. Because to our clients, it is.

Excellence isn't a finish — it's a decision made on every commit, every architecture review, every log line we choose not to ignore. We ship systems that hold up Monday at 3 a.m., not demos that shine on a Friday slide.

Robustness is our default. Tests, observability, reproducible deploys and considered rollbacks from day one. What we deliver can be operated, audited and evolved without a rewrite.

And professionalism goes beyond the code: clear communication, honest timelines, documented decisions. We work as partners to your engineering — not as one more vendor.

01 / Services

Three disciplines, one obsession: that it works under real load.

We're with you from strategy through deployment. We don't ship proofs of concept — we ship systems your team can operate Monday morning.

AI Integration & Consulting

Private systems, custom models

Practical AI for your business — from private knowledge assistants and document automation to custom LLM integrations. Built for companies that need outcomes without giving up control of their data.

  • Private RAG systems
  • On-prem LLM deployment
  • Autonomous agents
  • Fine tuning
02

Custom Applications

Custom applications · web and desktop

Custom software for web and desktop — from containerized full-stack platforms to native applications for demanding use cases. Enterprise architecture, solid performance, one team from MVP to production.

  • Full-stack web platforms
  • Native desktop applications
  • Systems architecture
  • APIs & microservices
  • Containerized deployment
03

Robotics & Simulation

Robotics & simulation · real-time systems

Systems for demanding industrial environments — robot control, real-time telemetry, 3D simulation and multi-vendor program generation. Where performance and reliability are non-negotiable.

  • Robot control
  • Real-time systems
  • Computer vision
  • Hardware integration
  • 3D simulation
02 / Selected work

Production systems. Measurable outcomes.

03 / Who we are

A studio, not an agency.

Senior-level communication, hands-on execution, and solutions built to last.

Founded by Sergio, a software architect with 18+ years of enterprise engineering experience, Fëanor's Code helps companies deploy AI systems that run entirely on their own infrastructure — giving them the power of modern language models without compromising on data privacy or regulatory compliance.

From industrial robotics platforms to full-stack web systems, we bring the architectural depth needed to integrate AI into real business operations — not just proofs of concept.

Whether you need a custom web or desktop application, a robotics & simulation system for your plant, or a private AI integration for your team — expect senior-level communication, hands-on execution, and solutions built to last.

  1. P/01
    Senior end-to-end
    Whoever designs the system builds it. No proxies, no handoffs to juniors. Architecture and implementation live together.
  2. P/02
    Built to last
    Production engineering from day one: tests, observability, reproducible deploys. Not demos in disguise.
  3. P/03
    Direct communication
    Honest timelines, documented decisions, no middle layers. You talk to the people building — always.
  4. P/04
    Architectural depth
    18+ years of enterprise engineering. We think in systems, not isolated features: what we ship can be operated, audited and evolved.
