Who does the work

There's one person behind Black_Index, building from Costa Rica for clients there and worldwide.

The same standard you see on this site applies to every client project: development, SEO and GEO as one discipline, no retouched templates, no promises we can't keep.

I work solo, start to finish — design, development, content, and the technical side of SEO and GEO don't pass through different hands. Black_Index is proof of that same standard: if we're selling the idea that generative AI can cite your business, this site had to practice it first — llms.txt, structured content, verifiable data.

We're new under the Black_Index name — the work isn't. Four real projects are still running in production today: PrimeTime PPH, DeUnaParts, La Villa Lavacar and TechniBM.
