🙋‍♂️ About Me

I'm Nisal, a 22-year-old Electronics & IoT Engineer from 🇱🇰 Sri Lanka — studying Electronic & Embedded Systems and self-taught in backend/API development.

My core focus is simple: make hardware and software talk to each other. I design circuits, build IoT systems, and write the APIs that connect them to the digital world. Whether it's a fire alarm that pings a server or a GPS tracker with a live web dashboard — I build the full chain, from the sensor to the screen.

• 🔭 Currently building: Flyback INSIGHTS — a full-stack editorial blog platform
• 🌱 Currently studying: Python algorithms + advanced embedded systems
• 💼 Open to: Freelance — IoT systems, embedded projects, hardware-connected APIs
• ⚡ Fun fact: I went from editing videos to designing PCBs — creativity takes many forms
