What I'm looking for

I seek database- or cloud-focused roles where I can lead migrations, optimize performance, implement IaC, mentor teams, and build scalable, cost-efficient data platforms.

I am a Database Engineer with 5+ years of experience focused on SQL Server and Oracle, cloud migrations, and performance optimization. I deliver measurable outcomes—improving availability from ~70% to 95% and reducing infrastructure costs by up to 60%.

As a hands-on technical lead, I own end-to-end database initiatives: architecture, migrations (Private Cloud and AWS EC2), query optimization, indexing, and backup and governance strategies. I have designed and implemented 100+ SQL reports, led three full migrations, and drove 20+ database projects that increased operational efficiency by ~35%.

I mentor junior engineers, enforce engineering standards, and collaborate with stakeholders to translate business needs into scalable, reliable, and cost-efficient data platforms. I am expanding expertise in AWS architecture and Infrastructure as Code (Terraform) to further automate and scale data operations.
