What I'm looking for

I’m looking for a senior role where I can design reliable SQL/NoSQL data systems for industrial/renewable energy analytics—owning SCADA ingestion, ETL, time-series modelling, and analytics-ready APIs—while collaborating with teams delivering real-world infrastructure outcomes.

I’m a senior data and database engineer designing and implementing SQL and NoSQL data platforms for industrial, renewable energy, real estate analytics, and educational technology environments. I build analytics-ready database models and deliver SCADA data ingestion, ETL pipelines, real-time processing, and strong data quality across high-volume time-series datasets.

Across solar, wind, and transformer programs, I’ve worked end-to-end on SQL/NoSQL systems using PostgreSQL/TimescaleDB, Cassandra, and SQL Server, including asset hierarchy and monitoring support for analytics and visualisation environments. I’ve also delivered an automated real-estate ETL platform integrating ~32 portals and banking sources, plus real-time duplicate detection and validation workflows—and I bring an academic research background in machine learning, data mining, and decision support systems.
