Engineering student from Batticaloa, Sri Lanka obsessed with AI, IoT, and hardware systems. Not just learning technology — building real products that solve real problems. Future founder. First principles thinker.
I'm Paul Rajeevan Nimalarajah — an engineering & technology student who spends most of his time thinking about how hardware, software, and intelligence can be combined to solve problems that actually matter.
My obsession is the full stack — from the microcontroller to the cloud, from the circuit board to the business model. I believe the next generation of great companies will be built by people who understand both sides of the physical-digital divide.
Inspired by Elon Musk's first principles thinking, I strip away assumptions and ask: what is the fundamental problem? A simple irrigation problem becomes an intelligent water management platform. A security gap becomes an AI-powered monitoring system.
I wake up early, work hard, stay curious. I'm not building a career — I'm building a company.
An intelligent IoT-powered irrigation controller using soil moisture sensors, real-time weather data, and machine learning to automatically optimize watering schedules. Reduces water waste by up to 40% while improving crop yield — solving a critical real-world problem for farmers across Sri Lanka and South Asia. Built with Arduino, GSM modules, and a Python-based control layer.
A hardware-software hybrid system using computer vision and anomaly detection to monitor network traffic and physical access points. Designed for small businesses and homes in developing markets where enterprise-grade security is cost-prohibitive. Making safety accessible.
The very site you're on — built as more than a portfolio. A statement of intent. A living document of a journey from engineering student to tech founder. Hand-coded with full animation, PCB trace systems, and cinematic design.
I'm open to internships, collaborations, mentorship, or just connecting with other builders and founders. If you see the same problems I do — if you believe technology should solve real things for real people — let's talk.
