At Baku State University, I engineer production ASP.NET Core services for payroll, tax, and financial reporting, and implemented QR-code generation and scanning for secure physical access control.

Alongside my university role, I’ve built seven live production websites end-to-end, covering API and database design through frontend development and deployment. My projects include travel booking, e-commerce, and education platforms built with TypeScript, Next.js, React, and Nuxt.

I also work on backend systems and security. At AppTech, I developed AI-integrated data-processing systems and automated deployments; as an independent security researcher, I confirmed a High severity finding in an Immuneﬁ audit competition and reviewed live DeFi protocols.
