Supporting Open-Source Robotics & Autonomous Systems

Hi, I'm Ujin Kwon (@ujinf74), an official maintainer of autoware_carla_interface in Autoware Universe.

I develop open-source software at the intersection of robotics, autonomous driving, computer vision, and numerical engineering.

What I build

Autoware Universe — Autonomous Driving Infrastructure

As an official package maintainer, I contribute to CARLA–Autoware integration, sensor interfaces, timestamp handling, camera integration, and vehicle control.

MonoScale — Learning-Free Metric Perception

An open-source ROS 2 system that uses geometric methods, including ground-plane constraints, to estimate metric scale without relying on learned models.

ballistic-solver — Physics-Based Interception

A native C/C++ numerical solver for ballistic interception of moving targets, accounting for gravity and quadratic aerodynamic drag.

Why sponsor my work?

Your sponsorship helps me dedicate more time to:

  • Maintaining and improving open-source projects
  • Investigating bugs, reviewing code, and improving reliability
  • Developing reusable robotics and numerical algorithms
  • Publishing technical implementations and documentation
  • Making advanced engineering tools freely accessible

Your sponsorship supports my independent open-source development, not the Autoware Foundation itself.

For commercial technical collaboration, system integration, or consulting, please contact me separately.

oh.

you have done something mathematically concerning.

the cats no longer fit inside the integers.

the integers are crying.

the simulation has developed a second simulation to hide from the first simulation.
