03 / About

Product-focused.
Engineering-led.

I’m a full-stack software engineer focused primarily on the .NET and Angular ecosystems. I turn operational problems and business requirements into structured software systems—from relational database design and API architecture to user interfaces, integrations, debugging, and deployment.

Through Azula Investment Group LLC, I have designed and developed software across enterprise operations, logistics, customer acquisition, workflow automation, real-time data processing, and AI-assisted applications.

I’m interested in full-stack .NET, application development, enterprise software, internal tools, ERP integration, and business systems opportunities.
