Who I am & what I’m about
Hi! I’m Sebastjan. I like to make things, explore new technologies, and occasionally write about what I’ve learned. Here are a few things about me.
-
My daily toolbox
Over two decades of hands-on engineering experience, with C, C++, Python, and a healthy dose of shell scripting at the core. Linux has been my natural habitat for more than 20 years ~ from low-level development and complex system integration to GPU-accelerated workflows, automation, and CI/CD pipelines.
-
Digital Twin & Simulation
NVIDIA Isaac Sim & Isaac Lab, digital twins and synthetic data generation. If it's dangerous or expensive to test in the real world, let's test it in the virtual one first.
-
I teach robots to think
Digital / Autonomous systems, ROS 2 ~ plus the reinforcement learning, sim-to-real and imitation learning that make robots actually learn. I work with IsaacSim and IsaacLab, in within NVidia Omniverse and teach robots tricks.
-
Pixels, film & VR
Computer graphics, visual effects, and real-time technologies ~ from high-end film compositing, rendering, and simulation to pioneering AR, VR, and immersive experiences. Deep expertise in procedural content generation, GPU optimization, shader development, and complex production pipelines, bridging traditional VFX craftsmanship with modern real-time engines.
-
Chief dog-annoyer
Off the clock, I excel at annoying my wife and our dog — a skill I've honed to near-professional level.
-
Secretly an Emacs user
On my home Linux box, I'm secretly an Emacs user. I've written several extensions for it, from an AI-facing email-composition aid to Markdown integrations for my own stuff.

Sponsoring Chhouk
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 :)

Nigel Tierney
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.

Guenever Goik
Senior Creative Producer
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.

Project Assistant · UNESCO
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.
