Full Stack Engineer · Building structured, deployable business systems from Sri Lanka 🇱🇰

👨‍💻 About Me

I'm a Full Stack Engineer with 3 years of project-based and freelance experience, specializing in building business-grade systems from the ground up — requirements, database design, APIs, dashboards, user roles, and cloud deployment.

My work focuses on turning real business operations into structured software: CRM workflows, SaaS platforms, admin dashboards, inventory systems, and internal tools.

"I don't just build features — I design systems that run businesses."

What I deliver on every project:

Requirements  →  System Design  →  Database Architecture
     API Layer  →  Auth & RBAC  →  Protected Dashboard UI
  Business Workflows  →  Reports & Exports  →  Deployment
