About Enoc Rafael

With over 25 years of experience in the IT sector and more than a decade specializing in the banking and financial industry, I help organizations transform complex data architectures into high-performance strategic assets.

My approach combines the technical robustness of Data Engineering with the strategic vision of Project Leadership, ensuring that every data pipeline or model is not only scalable but also meets the strictest standards of quality and regulation.

How can I add value to your project?
Data Engineering & Cloud: Design and implementation of end-to-end architectures and scalable ETL/ELT pipelines (Azure), optimizing the processing of large volumes of information.

Data Governance & Compliance: Specialist in governance frameworks, traceability, and data quality for highly regulated environments, ensuring the total reliability of critical reporting.

High-Impact Project Management: Experience leading agile cells (Scrum) and traditional frameworks (PMI), managing teams of up to +100 people and aligning technical objectives with business strategy.

Proven impact in figures:
Operational Efficiency: 50% reduction in pipeline processing times.

Reliability: 80% increase in data quality and fidelity for decision-making.

Productivity: 50% improvement in the performance of data teams under my role as Product Owner.

Why work with me:
In addition to my corporate experience, I have a strong background as a university lecturer in areas of programming, databases, and process optimization. This allows me not only to execute top-tier technical solutions but also to communicate them clearly to non-technical profiles and mentor teams to reach their full potential.
