Ph.D. in Computational Geometry. Former CTO of an AI startup. Chronic overthinker. Currently building the future of design at Braid Technologies.
I'm a researcher at Braid Technologies in Tokyo, working on geometry generation and design automation. It's a small team with an ambitious goal, and the problems are genuinely interesting. My dream place, in a nutshell.
Before this, I spent six years at Corpy&Co. — first as Chief Scientist, then as CTO. The engineering team grew from 10 to 70 during my tenure, shipped over 50 AI projects for clients across manufacturing, automotive, and healthcare, and built CONFIDE, an AIOps platform for quality-critical environments. It was hard work, and I learned a lot.
My background is in applied mathematics. For family reasons, I interrupted my undergrad studies for a couple of years and ended up in Italy, doing something completely different. I eventually went back to Greece, finished my degrees, and did my Ph.D. on triangulations of hyperbolic surfaces in France. The algorithm I developed is now part of CGAL, the largest open-source library for computational geometry. My current work is strongly related to my academic background, which was a big reason for deciding to join the team at Braid.
Highly technical R&D role directly relevant to my Ph.D. experience. My work focuses on geometry generation, modeling, computational design, design optimization, and automation. At Braid we're building the future of design.
Expanded responsibilities at Corpy to include higher management and strategic decisions. Grew the Engineering team to 70 members while overseeing technical R&D.
Led technical R&D across multiple AI/ML projects. Directed work for major Japanese clients in the automotive, manufacturing, and healthcare domain. Developed the first version of CONFIDE, a MLOps platform with XAI and QA tools for manufacturing.
Developed game streaming client applications for Samsung TVs. I used proprietary SDK to enable full-HD gaming at 60fps. I also did some research on frame upscaling with neural networks.
Applied research in Computational Geometry. Formulated and implemented an algorithm for constructing periodic triangulations of hyperbolic surfaces. This research is now part of the CGAL open-source library.
Applied geometric processing to medical research on abdominal aortic aneurysms. My first peer-reviewed journal, and the one that's dearest to me.
Developed business software solutions. Built tools for Italian cadastral PDF parsing, reimplemented the tax calculation engine for the 730 tax declaration.
Developed order-taking applications for Windows and Windows CE devices. My first experience with VB.NET, WPF, and Android programming.
A detour from university that turned out to be one of the more memorable experiences of my life. I worked with one of the experts in the field of officinal plants and he taught me more things than I could recount.
The AI/ML projects below are from my time at Corpy&Co. Technical details and client information are intentionally limited.
An AIOps platform built to facilitate AI adoption in mission-critical manufacturing environments. Covers data management, annotation, generation, model training, and explainability. CONFIDE directly addresses the two main barriers to AI adoption, which are the "black box" problem and the lack of quality assurance.
Fundamental research on Quality Assurance for black-box and white-box LLMs. Investigated robustness to prompt transformations and formulated preliminary QA principles.
Quality Assurance for Object Detection in autonomous vehicles. Comparative study of models under SOTIF and PEGASUS principles for ADAS suitability.
Custom method for detecting unknown objects with a one-step object detector. State-of-the-art performance in domain, used for obstacle detection.
Algorithm combining GANs and Genetic Algorithms to optimize industrial battery manufacturing processes while maintaining feasibility constraints.
Real-time calving event detection system. AI model integrated into a notification system to ensure calf safety during the calving process.
Periodic Delaunay triangulations of the Bolza surface. This is the code I produced during my Ph.D., and it is part of the largest open-source computational geometry library.
Geometry-based methods to determine morphological changes in abdominal aortic aneurysms between scans (initial detection and follow-ups). Published in a peer-reviewed journal.
Algorithm finding optimal tension parameters for geometric continuity at defined control points on a sphere. C++ implementation with visualization.
"The personal journal of a foreigner in Japan. Fatherhood, career, cultural shocks, mental health -- I've got it all covered."
Writing is my therapy. There is no agenda, no schedule, no theme. Just me and my thoughts, whenever I need to take a step back and organize the chaos in my mind. I hope my son will read it when he grows older, hoping that he gets a glimpse into my experience as a father and person. If that speaks to some like-minded soul, that's sublime.
Read on SubstackMy name is Iordan, not Lordan (with an uppercase 'i'). A common mistake, but why would I write my name in lowercase?!
Born in Bulgaria, but I'm a Linguri (the nomadic Boyash tribe). Also known as Ludari or Rudari. We speak a language derived from Latin with Bulgarian elements.
I speak Bulgarian, Greek, English, Italian, French, and Boyash. I can make it through a medical visit in Japanese, and I can make terrible puns, but no business meetings yet. I am also getting better at Japanese children's songs.
I compulsively respond to everything. Still learning to avoid scams.
