I’m a Data & Visualization Engineering Professional specializing in building data platforms, analytics solutions, business applications, and workflow automation.

My work sits at the intersection of Data Engineering, Business Intelligence, Cloud, Microsoft Power Platform, and Automation — transforming complex operational processes and raw data into scalable, accessible, and action-ready solutions.

🧩 Data Engineering Design and build ETL/ELT pipelines using Python, SQL, Spark, Azure Data Factory, Databricks, AWS Glue, Redshift, and cloud-native technologies.

📊 Data Visualization & Analytics Develop interactive dashboards and analytical solutions using Power BI, Sisense, Tableau, and QuickSight, with a focus on usability, governance, and business insights.

⚙️ Business Process Automation Build automated business workflows using Power Apps, Power Automate, SharePoint, and Microsoft 365 — replacing manual processes with structured digital applications.

☁️ Cloud Engineering Build and automate data solutions across Azure and AWS with an emphasis on scalability, security, CI/CD, lifecycle management, and operational reliability.

🧭 Location Intelligence Integrate GIS, GeoJSON, spatial SQL, GPS data, APIs, and interactive maps for fleet monitoring, route analysis, and location-based analytics.
