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
These are what I do. Everything else is a supporting skill.

Tools I use to build complete, polished projects — not my headline, but part of the toolkit.
|
Real-time GPS tracking — Arduino hardware feeding live location data through a Node.js API to a MERN web dashboard. Hardware and software as one system.
|
An AI-powered IoT fire detection system — smart embedded hardware with real-time alerting over the network. Sensors to server, end to end.
|
|
UltraGuard — a cross-platform digital wellbeing system with DNS filtering, always-on VPN, and device policy management for Windows & Android. |
A dark-themed tech editorial platform — Node.js API backend, Supabase database, React frontend, and a full Storybook component library.
