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 - embedded systems and robotics engineer, based in Colombo, Sri Lanka.
Engineering undergraduate at the University of Moratuwa. I start at the hardware - Verilog and VHDL on FPGAs, firmware on ESP32s - and build robots and software on top of it.
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 graduate roles, internships and research collaborations in embedded systems and robotics.

A vision-guided quadrotor for GPS-denied flight, built around a Jetson Orin Nano and an Orbbec Gemini 336 depth camera on a laser-cut carbon fibre airframe. Final year project, in progress.
Two low-cost LiDAR scouts stream scans and odometry over micro-ROS to a Raspberry Pi coordinator that merges them into one live occupancy map. Two scouts explored faster than one.
A camera-to-VGA edge detection pipeline in Verilog on a Basys 3, with a streaming Sobel core that outputs one pixel per clock at 640×480, verified bit-exact against a NumPy model.
A depth camera spots an incoming shot, an Extended Kalman Filter predicts where it will cross the goal line, and a servo swings the keeper there. Team build for IESL Techno 2025.
A nutrition tracker for Sri Lankan rice and curry: a Flutter app turns biodata into portion sizes, and a lunch box with volume guides replaces measuring cups. Brainstorm 2025 finalist.
A 4-bit processor in VHDL on a Basys 3 FPGA - register file, ALU, program counter, decoder and 7-segment driver, each verified by its own testbench - plus an extended second revision.
Team Sentinels at IESL RoboGames 2024: two maze rounds in Webots, then a hardware final sorting coloured cubes with a Kobuki base, a Kinect camera and a Raspberry Pi 5. University category finalist.
Six-month internship at GTN Technologies building Java and Spring Boot services on Kafka and Redis that keep live market data accurate, including a running average trade price for thousands of stocks.
A procurement dashboard for ACL Cables tracking USD/LKR, LME copper and aluminium, flood and drought risk, and news scored by a FinBERT model retuned to read like a buyer. Team of five, demoed to ACL.
A core banking proof of concept where the rules live in MySQL - 25 tables, stored procedures, triggers and scheduled events - with a React and Express app on top. Third-semester project, team of five.
An ESP32 pill box that sets its clock from the internet, rings two dose alarms with a snooze, and warns when a DHT22 sensor sees storage temperature or humidity go out of range.
