About Me & Technical Stack

Engineering Skills & Core Technologies

A structured breakdown of my full technical stack spanning web & mobile engineering, backend APIs, cloud infrastructure, SIEM security, and IoT firmware.

Ishara Mewan

Hi, I'm Ishara Mewan. I am a versatile software engineer with extensive hands-on experience building full-stack web platforms, native Android & mobile applications, robust backend microservices, and custom embedded IoT solutions.

I bridge intuitive UI/UX design with reliable system architecture. My background spans frontend frameworks, scalable database design, automated DevOps pipelines, and enterprise security tooling (Wazuh SIEM, CrowdSec IPS) to ensure applications are resilient from end to end.

Whether engineering custom IoT sensor networks or high-availability cloud platforms, I focus on clean code, strong security postures, and delightful user experiences.
