Over 15+ years, I have designed and built multiple database-driven software systems from the ground up. My work includes a research database serving 10,000+ users, accounting software, statistical reporting systems for government, and virtual exhibition platforms. Each project involved full ownership from requirements gathering to final deployment.

I focus on clean database design, complex SQL query optimization, and user-friendly interfaces. I have worked with MySQL, PostgreSQL, SQL Server, and DB2, designing schemas for 30–50 applications. My systems are built for scalability, data integrity, and real-world usability — not just technical features.

Beyond coding, I manage coordination with stakeholders, resource planning, system upgrades, and cross-team collaboration. I ensure each system solves real business problems and remains maintainable long-term. This end-to-end ownership has been key to delivering successful, production-ready software at scale.
