Javier Fernandez Salguero

I help companies turn scattered data into fast, reliable decisions. I've spent over a decade moving between backend development and data, and for years I've been fully dedicated to designing data architectures and dashboards that business teams actually use, not just glance at once.

My day-to-day combines data engineering (Microsoft Fabric, Databricks, Data Factory, AWS Glue) with analytics and visualization (Power BI, Tableau, SSRS), allowing me to understand the problem end-to-end: from data ingestion and cleaning to the report a director reviews before making a decision. This dual perspective, engine and dashboard, is what sets me apart: I don't just deliver a pipeline or a dashboard, I deliver a data system that works and that someone in the business understands without depending on me to interpret it.

I currently work as a Data Engineer at ENCAMINA and previously spent over four years at Plexus Tech leading BI and data engineering projects for various sectors, after a stint as a backend software engineer that gave me a solid foundation in good development practices. I am a Microsoft Certified Power BI Data Analyst Associate and an Oracle Autonomous Database Cloud Certified Specialist.

I work 100% remotely, with clear and frequent communication, and I adapt well to both short, well-defined projects and longer collaborations where you need someone who understands the business, not just the technology. If you're looking for someone who cares about your data telling a useful story, let's talk.
