01 — About Me

Turning Technical Concepts Into Dependable Solutions

I am a software engineer focused on building practical, resilient systems across web, hardware, and desktop environments.

My work spans the full engineering spectrum. As the Team Leader & Full-Stack Engineer on Vendly.lk, I spearheaded our team's product development: architecting user flows and wireframes in Figma, structuring modular React frontend and Flask backend services, integrating Firebase databases, and maintaining our GitHub development roadmap.

Beyond the browser, I build autonomous IoT solutions using ESP32 and Arduino, developing low-level C++ firmware that reads real-time environmental sensors and dispatches encrypted cloud alerts via Telegram.

Whether deploying a distributed web app or optimizing embedded firmware loops, my philosophy is simple: write clean code, eliminate friction, and build things that work reliably.
