José F. Sánchez · Authority Record

I am a librarian first. Everything else — the open archives, the field recordings, the systems architecture, the e-commerce stores — is what happens when someone trained at the Colegio de Bibliotecología (UNAM) decides that a catalogue is not furniture but living infrastructure. Preserving tangible and intangible cultural heritage, and engineering applied library science.

Information Decay & System Friction

Disorganized information and superficial systems cost millions

Unindexed digital archives, ad spend without attribution, disconnected e-commerce catalogs, and ephemeral platforms destroy value. Real permanence requires library science and senior engineering.

DECAY 0x01 — KNOWLEDGE LOSS📜 Disorganized Archives

Cultural and corporate knowledge buried in unindexed formats that search engines and AI crawlers ignore.

DECAY 0x02 — COMMERCE FRICTION🛒 Unstructured SKU Data

E-commerce storefronts failing to convert because product taxonomy, categories, and attributes are chaotic.

DECAY 0x03 — ACCOUNTABILITY🕳 Junior Handoffs

Paying senior consulting fees only to have your technical architecture managed by inexperienced junior staff.

DECAY 0x04 — MEASUREMENT📉 Blind Ad Spend

Investing heavily in ad campaigns without server-side attribution or clean GA4 BigQuery pipeline clarity.

DECAY 0x05 — DISRUPTION🔍 Invisible in AI Search

Relying solely on legacy SEO while consumers pivot to AI answer engines like ChatGPT and Perplexity.

DECAY 0x06 — SOVEREIGNTY🔐 Vendor Lock-In

Renting proprietary platforms that hold your customer data and digital assets hostage if you change providers.

The Difference

A junior agency is not a senior practice

Anyone can sell ad spend or build a basic template. Almost no one engineers integrated selling systems backed by 30 years of systems practice.

Who this is engineered for

Not every business needs senior information architecture. These are the organizations that do.

🚀 Founders & PyMEs Businesses that need enterprise-grade AI, paid ads, and web systems without hiring an expensive in-house CTO.
📚 Institutions & Open Libraries Institutions needing deeply indexed, catalogued, and preserved cultural heritage repositories.
🛒 E-Commerce DTC Brands Stores scaling past $10k-$100k/mo that require structured product taxonomy, CAPI, and CRO.
🤖 AI & Automation Builders Organizations looking to run private LLMs, custom RAG knowledge bases, and autonomous AI agents.
The Human Behind The Architecture

Josef Sánchez

Founder and senior systems architect of SESY.AI. Thirty years across software engineering, systems architecture, DevOps, CI/CD, and AI strategy — plus a Master's in Library and Information Studies from UNAM, which is precisely why everything here is documented, catalogued, and reproducible.

JOSEF.SESY.AI serves as the authority record and personal repository for Josef Sánchez. That means the same architectural discipline large enterprises pay dearly for, delivered directly, without layers, account managers, or a script standing between you and the person doing the work.

When you book a call you talk directly to the founder. This is not a high-volume commodity agency — it is a signature practice with a name on it.
