I'm a Computer Science & Engineering undergraduate at the University of Moratuwa, Sri Lanka. I enjoy building practical products across the stack—from intuitive web interfaces and reliable backend services to ESP32 firmware and cloud infrastructure.
My current focus is on:
- designing maintainable backend systems and APIs
- learning microservices, distributed systems, and cloud architecture
- building full-stack products with strong engineering foundations
- connecting embedded devices to dependable cloud services
