Message

At Global Energy for Investment and Industry, I build and maintain Python, Pandas, SQL, and Excel workflows to process operational data. I also develop Power BI dashboards and KPI reports for IT service performance, ticketing, inventory, and procurement.

I analyze helpdesk and ITSM data, including SLA compliance, resolution times, overdue cases, and workload distribution. My work also includes automating reporting and validating and standardizing data across operational and multi-site datasets.

At OneHealth, I processed Arabic and multilingual datasets for LLM training, evaluation, and data-quality initiatives. I developed transformation workflows with Python, SQL, and dbt, and performed profiling, cleansing, and validation.

Earlier, at Telecom Egypt, I developed Power BI and Tableau dashboards to monitor business KPIs and operational performance. I also developed IoT and smart-device prototypes during my internship at AAST, improving hardware prototyping efficiency by 40% through CNC routing and firmware optimization.
