About FCT Technologies

A software company that
runs on its own AI.

FCT Technologies is a Chicagoland software company building marketing websites, web and mobile applications, AI automation, and Second Brain OS — the file-based AI brain a business owns. We run on the same Second Brain OS architecture we install for clients: it's how we move fast across every lane and hand off work you fully own, built to keep making sense long after launch.

Visibility

Built to be found.

Semantic HTML, structured data, technical SEO, and GEO-ready content shapes. Every page is built for both humans and the AI systems that increasingly answer their questions.

Speed

Built to be fast.

Astro statics, optimized assets, careful JS budgets. Motion is lazy-loaded and respects reduced-motion, so the page never blocks on it. Performance is a default, not a phase.

Maintainability

Built to be evolved.

Clean APIs, stable data models, predictable boundaries. The work should be readable six months later, by you or your next developer.

The founder

Fernando Caudillo Tafoya

Founder · Software engineer · Operator

UIC computer science, software engineering concentration. Based in Elgin, Illinois. Builds in Swift and SwiftUI for the Apple ecosystem, Astro and TypeScript on the web, Python and FastAPI on the backend, and runs an FCT-internal Second Brain OS instance across all of it.

That internal AI operating layer is how FCT moves like a larger shop — it carries the standing work so engineering effort lands where it matters. You get direct founder involvement, clear milestones, and work that stays yours: source, files, schema, and handoff notes included.

"What we do in life, echoes in eternity."

How a project starts

Three steps. No drama.

  1. 01

    Clarify the bottleneck.

    What is the actual problem? Lead generation, manual workflow, no AI workspace, software direction. The work starts where the cost is.

  2. 02

    Pick the right first milestone.

    The goal is a usable launch slice — not over-building before the business has signal. Risk drops every time something real ships.

  3. 03

    Build with clean handoff in mind.

    Code ownership, documented decisions, predictable next steps. The system stays maintainable after launch whether or not FCT stays on retainer.
