At Dotcom IoT LLP, I analyzed real-time data from more than 1,000 devices, identifying error patterns, telemetry gaps, and performance trends.
I developed Power BI dashboards with DAX and Power Query to give firmware and systems teams a clearer view of device health, recurring issues, and operational KPIs.
I prepared analysis-ready datasets using Python, PostgreSQL, and Excel, and wrote SQL queries to extract operational data. I also worked with firmware and systems teams to investigate anomalies and recurring data issues, improving telemetry quality and reporting reliability.
In personal projects, I developed a SQL and Power BI sales analytics dashboard to track sales, profit margins, customer performance, and regional sales. I also analyzed public German datasets to explore the relationship between public transport activity and energy demand.
