Senior Oracle PL/SQL & Data Engineering Services
With over two decades of rich cross-industry experience, I offer expert-level services in Oracle database development and data engineering. My mission is to help businesses harness the power of their data by modernizing infrastructure and optimizing operations. My extensive background in complex, high-volume transactional environments ensures that every solution I deliver is built for reliability, security, and peak efficiency, providing a trusted partnership to senior stakeholders.
Core Expertise
Oracle PL/SQL & Database Development: I specialize in the full software lifecycle, from designing and architecting optimal database schemas to building robust custom stored procedures, functions, packages, and triggers. A core part of my service is advanced performance tuning, where I conduct in-depth analysis and optimization of both SQL queries and PL/SQL code. This work has a proven track record of significantly reducing execution times and improving overall system efficiency, which is critical for business operations and large-scale batch processes.
Data Migration & ETL: My services include the full scope of ETL (Extract, Transform, Load) solutions for large-scale data migrations. I develop and execute comprehensive strategies to ensure seamless transitions between systems, from managing multi-million record policy migrations to creating robust data reconciliation frameworks. These frameworks are crucial for validating data integrity post-migration, providing peace of mind and mitigating business risk.
Legacy System Modernization: I am an expert in modernizing outdated technical landscapes. This includes re-engineering entire suites of legacy programs, such as my experience transforming COBOL batch systems into modern, highly efficient PL/SQL packages. My work improves not only the maintainability and performance of these systems but also enhances their scalability and security to meet today's business demands.
Data Analytics & Automation: Leveraging my proficiency in Python (Pandas, NumPy, Statsmodels), I provide foundational data analytics solutions. This involves developing automated scripts for efficient data cleaning, validation, and preparation. The goal is to transform raw data into a reliable format ready for business intelligence platforms, reporting, and predictive analytics, enabling smarter, data-driven decisions.
