Md Nafis Rahman

I’m a Systems & Data Analyst with 3 years of experience across data analysis, database administration, and process automation in enterprise systems. I use SQL for extraction, querying, validation, and reporting, and Python to automate routine work and improve analytical efficiency. I’ve handled large-scale data import/export operations to ensure data integrity and quality across environments, and I translate complex vulnerability and performance findings into actionable insights for management.

In my current role at CGI, I validate data consistency post-migration using compare reports, and I support structured pre- and post-migration checks using STAT/Application Designer. I also generate AWR (Automatic Workload Repository) reports to analyze performance trends, identify bottlenecks, and guide data-driven optimization decisions—while resolving system/data issues through support tickets with cross-functional technical teams. Beyond analysis, I contribute to data governance (SOX audit profile reviews) and manage SQL-based user/role administration with clear documentation of standard database procedures, including automation work such as a Flask-based vulnerability report automation tool and daily health-check automation.
