I am a Senior Database Administrator with 12+ years of hands-on experience designing, managing, optimizing, and maintaining reliable database systems for startups, small businesses, and large enterprise applications.
Over the years, I have worked on large-scale PAN India CRM platforms and high-traffic production systems where database availability, performance, and data integrity were essential to daily operations.
My expertise goes beyond writing SQL queries. I focus on building stable, high-performing, and scalable database environments that can handle real-world business demands.
◆ Database administration and architecture (SQL Server, PostgreSQL, MySQL)
◆ Query optimization, indexing, and performance tuning
◆ Troubleshooting slow queries, blocking, deadlocks, and production issues
◆ Backup strategies, recovery planning, and disaster preparedness
◆ Database migration, upgrades, and scaling solutions
◆ Ongoing DBA support and performance monitoring
In addition to my DBA expertise, I have strong hands-on experience in C#, .NET, .NET Core, Web APIs, Angular, and AI-enabled applications. This full-stack understanding helps me bridge the gap between databases and applications, ensuring optimized solutions from the backend to the user interface.
Whether you are experiencing database performance bottlenecks, planning to scale your application, or need a reliable expert to maintain your production systems, I can provide practical, real-world solutions.
I also help businesses build and maintain web, desktop, mobile, automation, and AI-powered applications using modern .NET technologies.
I believe in delivering clean solutions, clear communication, and long-term reliability-not just quick fixes.
