Senior database professional driving performance, migrations, and AI-driven SQL optimization.
NepalWhat I'm looking for
I am a results-driven senior database professional with over 15 years of experience designing, architecting, and optimizing large-scale database systems across SQL Server, PostgreSQL, Oracle, MySQL and NoSQL stores.
I have led major migrations and performance initiatives—most notably a SQL Server to PostgreSQL migration with zero data loss and 5x faster routines—and architected solutions that improved query performance by up to 60%.
My work includes implementing AI-driven SQL optimization, automated ETL and data pipelines, and cloud-based data processing (AWS S3, Aurora, RDS, Batch/Lambda), which reduced manual tuning and processing time while improving accuracy.
I bring hands-on leadership, strong operational discipline in backup/recovery and security (data masking/encryption/HIPAA compliance), and a history of mentoring teams and delivering scalable, cost-saving database architectures.
