OUR 3 SERVICE PILLARS

The Three Service Pillars

We don't offer 40 generic services. We do three things at a world-class level, with battle-tested principals running every engagement.

FOUNDATIONAL PILLAR

Web Analytics & Precision Measurement

Precision Telemetry & Enterprise Measurement

Don't guess. We engineered the tools the industry runs on.

Most analytics implementations are leaky sieves losing 20–40% of their data to ad-blockers, iOS ITP restrictions, and brittle client-side tags. We architect resilient first-party measurement systems, server-side Google Tag Manager (sGTM) containers, and streaming BigQuery pipelines that capture true customer journeys while staying ruthlessly compliant with LGPD and GDPR.

Core Capabilities:

  • Server-Side Tracking: Zero-data-loss sGTM on custom edge domains with 1st-party cookie resurrection.
  • GA4 & BigQuery Streaming: Raw event export schemas, deterministic user unification & session reconstruction.
  • Attribution & Modeling: Algorithmic multi-touch attribution & offline conversion imports (OCI).
  • Privacy & Compliance: Strict Consent Mode v2 and zero-PII data redaction pipelines (LGPD/GDPR).

The Cereto Edge: We literally co-authored the book on enterprise measurement. When Fortune 500 war rooms hit catastrophic tracking issues, our founders are the ones they called.

NEXT-GEN INTELLIGENCE

Agentic Engineering & Production AI Systems

Autonomous Multi-Agent & LLM Engineering

Move beyond chatbot gimmicks. Autonomous agents that actually execute.

The world doesn't need another generic chat wrapper that hallucinates answers and breaks in production. We design deterministic, autonomous multi-agent systems and LLM application architectures where agents reason, invoke typed tools, verify intermediate outputs against strict contracts, and autonomously resolve complex business workflows.

Core Capabilities:

  • Multi-Agent Orchestration: Coordinated agent swarms, shared append-only journals, DAG task dispatchers.
  • Deterministic Tool Calling: Strictly validated typed interfaces, sandbox boundaries & self-healing loops.
  • Enterprise RAG: Hybrid vector/lexical retrieval, semantic chunking & citations verification.
  • Continuous Evals: Automated harnesses measuring grounding, accuracy, token cost & latency.

The Cereto Edge: We treat AI like distributed systems engineering, not magic. If an agent cannot verify its own work against a deterministic compiler or test suite, it doesn't ship.

HIGH-VELOCITY INFRASTRUCTURE

Modern Edge Web & High-Leverage Software

Elite Craftsmanship & Edge Web Applications

Sub-second latency, zero bloated frameworks, and software built to last.

We build web applications and digital platforms engineered with uncompromising craftsmanship. By pairing lightweight, modern frameworks with global edge computing (Cloudflare Workers, Pages, D1, KV), we deliver digital experiences with zero cold starts, near-instant page loads, and bulletproof accessibility.

Core Capabilities:

  • Serverless Edge: Cloudflare Workers, Pages, D1 distributed SQL & KV caches (sub-30ms TTFB).
  • Astro Island Architecture: Zero-JS-by-default page generation with 100/100 Core Web Vitals.
  • Accessible Headless UI: WCAG 2.1 AA compliant interfaces built with Base UI (@base-ui/react).
  • Type Safety: End-to-end type contracts from edge D1 schemas to client view transitions.

The Cereto Edge: No 15-megabyte JavaScript bundles. No sluggish corporate page weight. Just elegant, hyper-optimized software that users love and developers enjoy maintaining.

MEET THE FOUNDERS & TEAM

Founders & Leadership

No outsourced subcontractors. You work directly with the veterans whose code runs on millions of devices. When you hire Cereto, you get the actual founders in the engine room.

Eduardo Cereto Carvalho

Founder, Principal Architect

Former Google Product Lead, open-source creator, and distributed systems architect.

Eduardo spent over a decade leading technical product engineering and developer platforms at Google. As Product Technical Manager and Technical Product Engineer, he drove core infrastructure initiatives across Google Analytics, Google Tag Manager, Google Data Studio, the Analytics BigQuery Export pipeline, and the global launch of Google Analytics 360 (GA360). In the open-source ecosystem, he authored pyboleto, Brazil's foundational banking slip library.

"Architecture isn't what looks clean on a whiteboard; it's what still executes predictably at 3 AM under 50,000 requests per second with zero data loss."

Augusto Cereto Carvalho

Co-Founder, Enterprise Telemetry Lead

10+ years leading DP6 war rooms, enterprise telemetry, and behavioral data systems.

Augusto is a veteran metrics architect with over a decade of battlefield leadership at DP6, Latin America’s foremost data consultancy. As Metrics Architect, Project Manager, and Google Analytics Certified Partner (GACP), he led mission-critical measurement transformations and real-time war rooms for premier enterprise institutions including Itaú, FCA (Fiat Chrysler), Walmart, Netshoes, HP, and Coca-Cola.
