About

Hi! I’m Sebastjan. I like to make things, exploring new technologies, and occasionally writing about what I’ve learned.

Out of the things I know most:

Robotics — autonomous systems, sensor fusion, motion planning, ROS 2
ML for robots — reinforcement learning, sim-to-real, policy training, imitation learning
Simulation — NVIDIA Isaac Sim & Isaac Lab, synthetic data generation, digital twins
AI / ML — training pipelines, computer vision, model deployment
Computer graphics — real-time graphics, augmented & virtual reality
Programming — C, C++, Python, Bash scripting
Systems — Linux administration, GPU workflows, CI/CD
VFX (Visual Effects) — compositing, simulation & rendering for film and real-time
I also excel particularly at annoying my wife… and our dog.

I am sponsoring Chhouk

Chhouk the elephant — Wildlife Alliance sponsorship certificate

Animals cannot speak for themselves, cannot ask for help, and cannot explain what happened to them. All they can do is endure. That makes it our responsibility — not someone else's — to step in when we can. Chhouk was found in a Cambodian forest in 2007, barely a year old, his foot destroyed by a hunter's snare. He survived because people chose to act. Supporting organisations like Wildlife Alliance is one small, concrete way to make sure more animals get that chance.

Feedback about me

Pam Earle

Creative Director · Ex-Yahoo/Tumblr

Working with Seb was an absolute pleasure, especially during our collaboration on the Augmented Reality (AR) project. Seb's contribution was instrumental in the development of our innovative AR tool. His ability to bring complex designs to life in the AR space was nothing short of remarkable. Seb possesses a rare blend of technical expertise and creative vision, which he leveraged to elevate our project to new heights. His proficiency in 3D modeling tools and techniques was evident in the quality and detail of his work. But what truly set Seb apart was his collaborative spirit. He was always willing to share his knowledge, offer constructive feedback, and assist team members, ensuring that the entire team benefitted from his insights :)

Award Winning Director · Creative Producer

Seb is an incredible person with a serious depth of talent, knowledge, and most importantly a deep passion to learn. His ability to take on each challenge and deploy the best technique necessary has been both a necessity and a joy for the success of Yahoo. A variety of skills that Seb demonstrated against delivering our company needs include: generating assets along with a pipeline for the largest executed augmented reality web platform, which generated 100+ Million AR experiences, and earning significant revenue; deploying scalable Houdini based solutions to generate ad and sports content; executing realtime experiences using Unreal game engine and deploying over 5G; managing a team of data and technical artists to execute and deliver on data driven storytelling; and most recently executing AI based solutions to help visualize the news. Hopefully, you will get a sense of his humble willingness to take on any task, our team's reliance on his innovative mind, and most importantly his incredibly kind personality and charm. I would be happy to recommend Seb to anyone who is lucky enough to scoop him up.

Seb is a tenacious and creative force. His wonderful creative skills are well supported by a never-ending quest to learn new techniques and programs. He has an excellent connection with engineering and product that really elevated what our platform could do. Best of all, Seb's "I've got this" attitude is inspiring to those working with him.

I worked with Sebastjan when he was leading in VTR London/Beirut. One of his main added value is the capability to work for long hours and speed in applying the feedbacks. In addition to the above, his creativity and quality of the deliverables were an asset to our post-production jobs.
