About

01
Nadeesha Jayamanne

I build systems that have to work in the physical world.

I am a Computer Science & Engineering undergraduate at the University of Moratuwa, specialising in Integrated Computer Engineering. My work sits where firmware, hardware and autonomy meet: autonomous drones, custom PCBs, maze-solving robots, and low-latency systems that cannot afford to be slow or wrong.

I have built a UAV platform and a containerised simulation environment for a national robotics competition, designed mass-producible robot PCBs for school teams, written a sub-millisecond Rust execution engine, and put a LoRa mesh radio on a breadboard to keep people talking when the cell towers go down.

I like problems that force several disciplines into the same room: a control loop that is also a thermal problem, a trading engine that is also a network-latency problem, a robot that is also a manufacturing problem.

Autonomous Drone Platform for IESL RoboGames (1 of 6)1/6
012025 to 2026Robotics / UAV

Autonomous Drone Platform for IESL RoboGames

A Pixhawk and Raspberry Pi UAV platform, plus a Docker image that runs Webots and ArduPilot SITL together, so competitors get a simulation-like development loop on real hardware.

022026Embedded / RF

Ranger: LoRa Mesh Communicator

A handheld off-grid voice, text and location radio on ESP32 and SX1276. Codec2 at 3200 bps, hardware AES-128, dual-core FreeRTOS scheduling, around 250 ms end-to-end voice latency.

BitCo: Low-Latency Trading Engine (1 of 2)1/2
032026Systems / Quant

BitCo: Low-Latency Trading Engine

A Rust execution engine for Polymarket BTC markets. Co-located on AWS beside the exchange (0.9 ms ping), sub-millisecond tick-to-order, and a risk manager that can veto every entry.

Custom PCB Line Following Robot for IESL RoboGames 2026 (1 of 3)1/3
042026Hardware

Custom PCB Line Following Robot for IESL RoboGames 2026

A line-following, distance-sensing ATmega328 robot designed for mass production: one board that school teams across the IESL RoboGames school category could build and repair.

LYNX & LYNX V2: MicroMouse (1 of 7)1/7
052018, 2025 to 2026Robotics

LYNX & LYNX V2: MicroMouse

A maze-solving MicroMouse across two generations. LYNX was the original build; LYNX V2 rebuilds it on a fully custom PCB with ESC-driven brushless motors and a purpose-built gear train, adding line following, colour detection and object handling.

Emergence Lab: Agent Simulations (1 of 3)1/3
062026Simulation

Emergence Lab: Agent Simulations

Eight in-browser complex-system simulations: flocking, ant colonies, predator-prey, N-body gravity, epidemics, with live parameter control and Web Worker compute.

Battlebot: LYNX (1 of 9)1/9
072025Robotics / Hardware

Battlebot: LYNX

A combat robot built around a high-RPM, high-torque horizontal spinning blade, with the chassis and drive designed to stay controllable under the recoil and gyroscopic loads a spinner generates.

Peltier Air Conditioning (1 of 3)1/3
082024Hardware / Thermal

Peltier Air Conditioning

An experiment testing whether Peltier thermoelectric modules could replace a compressor for air conditioning, using two 6V modules and a water-cooling loop to dissipate heat, and characterising where the approach falls short.
