Iguardia Data Engineer · Integration Specialist · BI Developer

I build the plumbing behind business decisions — ETL pipelines, ERP integrations, and analytics platforms that turn raw operational data into something executives can actually use. I specialize in SAP Business One ↔ Odoo integration, Microsoft Fabric, and Power BI.

Data infrastructure that actually ships.

Most data work fails not because the math is hard, but because the pipes leak. I make the pipes not leak — and then I make them fast.

01 / ERP INTEGRATION

SAP B1 ↔ Odoo, end to end

Bidirectional synchronization between SAP Business One (HANA) and Odoo using REST APIs and XML-RPC, orchestrated with N8N. Duplicate control, data validation, and automated reconciliation flows that reduced manual errors to near zero.

02 / ETL & WAREHOUSING

Pipelines that don't break at 3am

SSIS-based ETL from SAP HANA into SQL Server data warehouses. Incremental loads, validation layers, and Liquibase-versioned schemas for repeatable deployments.

03 / BI & ANALYTICS

Power BI, but engineered

Dashboards with optimized data models and DAX measures. Hands-on with Microsoft Fabric (Warehouse / Lakehouse) for modern lakehouse architectures. Copilot-driven insights for non-technical stakeholders.

04 / DATABASE OPERATIONS

Production DB administration — quietly, reliably

Backups, performance tuning, monitoring, and critical incident resolution for production databases. Liquibase for schema version control. The work nobody notices when it's done right — and everyone notices when it's not.

Experience that compounds.
