Full Stack Software Engineer | Java | Spring Boot | Angular | React | AWS | System Design

I'm a Full Stack Software Engineer with 3.5+ years of experience building scalable healthcare and SaaS platforms. My work spans frontend architecture, backend services, cloud deployment, and platform engineering.

Over the years, I've built configurable onboarding platforms, dynamic form engines, audience segmentation systems, RBAC solutions, and microservices-based applications serving thousands of users across multiple countries.

I enjoy designing systems that are flexible, maintainable, and easy to scale—from idea and architecture to deployment and production support.
