The same portfolio, arranged as somewhere to fly rather than something to scroll. Take the controls and the projects, the background and the contact details are out there waiting to be reached. Nine markers, and nothing is hidden behind being good at it — every one is a click away in the list underneath, and all of it is written out in plain text below.
Sansika Suhan Waduge — robotics and embedded systems engineer, based in Colombo, Sri Lanka.
Engineering undergraduate at the University of Moratuwa. Most of what I do sits across a boundary: ROS 2 and Jetson-class compute on one side, processors and image pipelines written in Verilog and VHDL on the other.
Working both sides has made me suspicious of abstractions I have not looked underneath at least once.
Robotics: ROS 2, micro-ROS, Occupancy-grid mapping, Kalman filtering / state estimation, 2D LiDAR, RGB-D perception, Webots.
Embedded & hardware: Verilog, VHDL, Vivado, Basys 3 / Artix-7, Raspberry Pi, Jetson Orin Nano, ESP32, Arduino.
Software: C++, Python, Java / Spring Boot, OpenCV, Redis / Lua, Apache Kafka, PostgreSQL, React, Docker, Linux.
Open to internships, research collaborations and interesting robotics problems.

A vision-guided autonomous quadrotor built around a Jetson Orin Nano and an Orbbec depth camera, with a laser-cut carbon fibre airframe. Final year project.
Two low-cost LiDAR scout robots explore a space together, streaming scans and odometry over micro-ROS to a Raspberry Pi coordinator that builds one live, dynamic occupancy map.
A camera-to-display edge detection pipeline in Verilog on a Basys 3 — OV7670 capture, a streaming Sobel core producing one pixel per clock, and live 640×480 VGA output, verified bit-exact against a NumPy model.
A depth camera spots an incoming ball, an Extended Kalman Filter predicts where it will cross the goal line, and a servo swings the keeper there — built for the IESL Techno 2025 exhibition.
A nutrition tracker built for Sri Lankan meals — a food database, an app that turns biodata into portion sizes, and a lunch box with volume guides instead of measuring cups. Brainstorm 2025 finalist.
A working 4-bit processor in VHDL on a Basys 3 — register file, ALU, program counter, instruction decoder and 7-segment display driver — plus an enhanced second revision.
Vision-guided control of a Kobuki mobile base on a Raspberry Pi with Kinect RGB-D input and OpenCV, alongside a Webots simulation environment for testing behaviours before hardware.
Internship at GTN Technologies — backend services and tools that keep live stock-market data accurate for a global trading platform.
An ESP32 pill box that keeps its own time from the internet, rings for each dose, and watches the temperature and humidity its contents are stored at.
