Project Name: Enterprise Data Processing & Reporting Platform
Tech Stack: Oracle 11g/12c, PL/SQL, SQL, UNIX, Shell Scripting
Project Overview:
Worked on a scalable enterprise data platform used by internal teams and external clients for reporting, reconciliation, and transaction processing. The system handled high-volume data loads with strict performance and data-quality requirements.
Key Contributions:
1. Designed, developed, and maintained high-performance PL/SQL packages, procedures, and functions supporting core product features.
2. Built robust data validation, reconciliation, and error-handling frameworks to ensure data accuracy for client-facing reports.
3. Optimized complex SQL queries using execution plan analysis, indexing strategies, and query refactoring, improving overall system performance.
4. Developed and supported batch processing workflows for daily and monthly data loads using PL/SQL and shell scripts.
5. Collaborated directly with clients, product owners, and business stakeholders to understand requirements and deliver enhancements.
6. Provided production support, including root-cause analysis, permanent fixes, and preventive improvements.
7. Ensured adherence to coding standards, release processes, and documentation practices in a product environment.
Impact & Results:
1. Reduced data processing time by 25–30% through SQL and PL/SQL optimization.
2. Supported multiple client releases with zero critical post-production defects.
3. Helped minimize manual intervention by automating validation and reconciliation processes.
