I specialize in data-driven software development with a focus on analytics systems and simulations. With three years of educational experience, I've collaborated on diverse projects, including designing a comprehensive SQL database for Formula 1 performance analytics covering over 692K records and creating a Java application for real-time queries. I also developed an event-driven airport runway simulator in C++, mastering the intricacies of scheduling and data management. My strong technical skills in Java, C++, and SQL, combined with my hands-on project experience, enable me to deliver efficient, high-quality solutions that enhance functionality and user experience. If you need a detail-oriented programmer who excels at transforming complex data into actionable insights, let's discuss how I can contribute to your projects.

Specialized in Systems Analysis and part-time maintenance (up to 20-30 hours/week) for legacy Powerbuilder / Oracle / Sybase / MS SQL Server environments. Productive on Day One. With over 20 years of specialized experience in PowerBuilder (v6.5 through v2022) and complex database environments, I provide the rare expertise needed to maintain, debug, and enhance mission-critical legacy applications. I specialize in the "plumbing" of legacy apps—ensuring stable SQLCA.DBMS connectivity and data integrity during system transitions. I possess the unique ability to step through established "black box" applications with little to no training, providing immediate value. Beyond coding, I bridge the gap between legacy systems and future goals by documenting existing functionality for developers, business analysts, and stakeholders to assist in eventual modernization strategies. Core Competencies: PowerBuilder Mastery: Expert work with PB versions 6.5, 8, 12.5, and 2016+, including the DIAMOND® Enterprise System and PFC frameworks. Database Expertise: Senior-level SQL, SQLCA.DBMS configuration, and Stored Procedure development for Oracle (Legacy to 19c), Sybase (v10, v12), and SQL Server. Modernized Documentation: I leverage modern AI-assisted tools to accelerate the analysis and summarization of legacy PowerScript logic, ensuring every finding is manually verified for technical accuracy. Industry Knowledge: Deep experience including Health Insurance (Diamond), Manufacturing, POS Systems, and Compliance Reporting. Whether you need urgent bug fixes, long-term system maintenance, or a technical guide to assist your modernization strategy, I am at ease collaborating with DBAs and Project Managers to deliver stable, documented results.
