I’m a Software Engineer with 3+ years building and maintaining enterprise-scale applications on .NET Core and Angular. I focus on owning backend architecture, REST API design, and secure authentication systems, while also leading complex frontend refactors.

On the backend, I architected a new enterprise .NET application from scratch with layered architecture (Controllers / Services / Repositories), implemented Repository and Unit of Work patterns, and set modular project structure conventions adopted by my team.

I’ve delivered security-critical work end-to-end, building JWT-based auth and RBAC, then identifying an XSS vulnerability risk and migrating to an HttpOnly Cookie-based system with Refresh Tokens—hardening security while preserving seamless session persistence.

On the frontend, I designed a metadata-driven Angular grid + filter framework used across 30+ pages and 10+ high-traffic reports, reducing development time for new modules by over 60%. I also led architectural refactoring of a complex legacy UI module (17+ page types) and executed an Angular 8 to v20 upgrade with complex breaking changes while ensuring zero downtime.
