About FCT Technologies

Built by one founder.
Engineered to outlast him.

FCT Technologies is a Chicagoland-based software studio. One founder, Fernando Caudillo Tafoya, doing the work himself — websites, applications, AI systems, and Second Brain OS, the file-based AI brain a business owns. The standard is software that keeps making sense after launch, with delivery you can actually read in a milestone tracker.

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. The site you're reading runs zero npm-dependency motion. 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.

The work is one person's signature. No agency layer, no junior pass, no offshore subcontractor. The trade-off is FCT takes one client at a time per lane — the upside is the founder is the one in your repo, in your meeting, and in your inbox.

"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.
