“I build robots, and the code that makes them think.”
Hello, world.
Hi, I’m Isiwara Mallawaarachchi.
Robots that find their own way
Sensor fusion, control systems and path planning, proven in simulation before the robot ever touches the arena floor.
Learning bucket list
Tools I use
Built to ship
End-to-end web applications: RESTful APIs in FastAPI and Spring Boot, React and TypeScript front ends, and relational data models in MySQL, built to ship.

A 4-bit processor written in VHDL and run on a BASYS 3 FPGA, each block verified with its own Vivado testbench.
A calendar that negotiates
A calendar that checks whether an event can actually happen, settles clashes by priority and reshuffles your day when plans change.
Next build
in progress.

Full-size micromouse · University category · SLIIT
A palm-sized robot that maps a 16×16 maze by itself and races to the centre. I built its electronics by hand and led the firmware: reading the sensors, working out where it is, keeping it steady and solving the maze. 2nd place on our first attempt.
