Electrical & Electronic Engineering Undergraduate

Hello, I'm Dinupa Devinda

Embedded Systems • Automation • Computer Vision

I build practical, low-latency systems that blend electronics, software and ML: from SMT-line conveyors and AGVs to Raspberry-Pi vision and Spring Boot APIs. Currently R&D Engineering Intern at Sri Lanka Telecom.

About

Multidisciplinary undergraduate focused on Electrical & Electronics Engineering with a solid foundation in computer science and management accountancy (CIMA Cert BA). I enjoy turning messy real-world constraints into reliable, maintainable systems and documenting them clearly.

Interested in: embedded Linux, edge ML, mechatronics, industrial automation, and sustainable hardware design.
