Data Engineering

Scattered data does not support decisions. We build the foundation.

We design and implement pipelines, data lakes and data architectures that integrate all your sources into a reliable, scalable and AI-ready analytics layer.

What happens when data has no foundation

These problems cost money every month and get more expensive the more they grow.

Data in silos — CRM, ERP, spreadsheets and third-party APIs that never talk to each other.

Handcrafted pipelines built on SQL scripts that break every time a table changes.

Reports that take hours to run because they query the production database directly.

Dirty, duplicated and inconsistently formatted data — each system with its own convention.

AI and machine learning are impossible because there is no reliable historical data foundation.

No governance: nobody knows who owns each piece of data, or what the official definition of a KPI is.

How data engineering solves it in practice

We implement Medallion architectures (Bronze → Silver → Gold) with ingestion from multiple sources via Azure Data Factory or Microsoft Fabric Pipelines, storage on Azure Data Lake Storage Gen2 and transformation with dbt or Databricks Notebooks.

The Gold layer feeds Power BI directly with data that is already modeled, cleansed and versioned. Every pipeline has orchestration, execution logs, failure alerts and technical documentation — nothing works as a black box.

A well-built data lake is not an infrastructure cost — it is the asset that multiplies the value of every analytics tool you already have.

Our data engineering methodology

A proven architecture that delivers value in short iterations — not a months-long big bang.

  1. Step 01

    Source discovery

    An inventory of all data sources, volumes, update frequency and priority analytics use cases.

  2. Step 02

    Architecture design

    Defining the architecture (Lakehouse, Data Warehouse or hybrid), choosing tools and the governance model.

  3. Step 03

    Ingestion and Bronze layer

    Ingestion pipelines for the priority sources running with orchestration, logs and alerts configured.

  4. Step 04

    Silver and Gold transformation

    Cleansing, enrichment and dimensional modeling for the analytics use cases defined in the discovery stage.

  5. Step 05

    Consumption and governance

    Connection to Power BI, documentation of the data catalog and training of the client data team.

What your organization gains

  • All sources integrated into a single, auditable analytics layer
  • Clean, transformed data ready for Power BI with no load on the production database
  • Complete history for trend analysis and predictive models
  • Pipelines with orchestration, alerts and execution traceability
  • Governance: data catalog, lineage and owner per data asset
  • A foundation ready for Copilot Analytics and machine learning
  • Horizontal scalability without rewriting the architecture
  • Lower costs from direct queries on production databases

Result cases

Projects inspired by real market implementations.

Retail / E-commerce

Integrating 12 sources into a unified data lake

Scenario

12 sources — ERP, CRM, marketplace, logistics API, cost spreadsheets — with no integration. The monthly report took 5 days and arrived inconsistent.

Solution

A Medallion data lake on Azure with automatic ingestion pipelines, a Gold layer modeled for Power BI and a full daily refresh in 1 hour.

12 → 1 integrated source Report in 1h, automated -100% manual consolidation
Energy / Industrial IoT

Telemetry pipeline for predictive maintenance

Scenario

IoT sensors generated temperature, vibration and pressure data with no structured storage — lost data and expensive corrective maintenance.

Solution

A telemetry ingestion pipeline on Azure, a feature layer on Databricks and anomaly models integrated into the maintenance dashboard.

-28% unplanned failures R$ 2.4M savings/year Data retained for 3 years
Financial / Fintech

Data warehouse for audit and compliance

Scenario

Operations auditing required cross-referencing data from 4 distinct systems with no structured history — a process that took 3 weeks.

Solution

A data warehouse with incremental ingestion, lineage documented in Purview and an audit dashboard with drill-down by operation, date and owner.

3 weeks → 4 days 100% lineage documented Complete audit trail

What you become able to do

  • Machine learning in production A structured historical foundation that feeds predictive models with reliable, up-to-date data.
  • Generative AI on your data Microsoft Fabric with Copilot Analytics operating securely over your internal data.
  • Regulatory compliance Lineage and catalog available for LGPD, SOX and sector-specific regulatory audits.
  • An autonomous data team Documented architecture and training so your team of analysts can evolve without ongoing dependency.

Why Yottaflow

Architecture for the future

We do not deliver quick pipelines. We design architectures that grow with volume and use cases — without a rewrite from scratch in 1 year.

Microsoft Fabric first

Specialists in Microsoft’s unified platform — without fragmenting your environment into disconnected tools.

Governance from the start

Data catalog, lineage and owner defined from the design phase — not as a retroactive documentation task.

Incremental delivery

First pipelines in production within weeks. We do not wait for the big bang — we deliver value in every sprint.
