Hello, my name is Arman Bablumyan.

I am a database developer with more than 15 years of hands-on experience designing, optimizing, and maintaining enterprise-grade database systems.

My work spans complex transactional systems, data warehouses, financial and regulatory reporting, and high-concurrency environments, with a strong focus on correctness, performance, and long-term maintainability.

Throughout my career, I have worked extensively with Oracle, PostgreSQL, SQL Server, and MySQL, building business logic inside the database, tuning critical SQL workloads, and designing architectures that operate reliably under real production pressure.

I also provide professional database consulting and development services for businesses that need expert support with performance optimization, SQL tuning, database architecture, migrations, reporting solutions, troubleshooting, and modernization of legacy systems. Whether the need is a short-term project, system review, long-term cooperation, or hands-on technical leadership, I help organizations solve real database challenges with practical and efficient solutions.

SQL-Versus was created to share practical knowledge gained from real projects and to provide clear, technical comparisons between database platforms.

This site is intended for developers, architects, and decision-makers who want fact-based comparisons, realistic examples, and a deeper understanding of how database systems actually behave in production.
