Twelve years in, the problems I find most interesting are still the ones where the system design matters as much as the execution — where getting the architecture right from the start is the difference between something that scales and something that gets rebuilt every six months. My background is in physics-based simulation, digital twins, and advanced manufacturing. That's an unusual starting point for someone building AI systems, but it shapes how I think about automation. I'm not asking, "what can we connect?" — I'm asking what decision this actually replaces, what happens when the model is wrong, and whether an engineer will trust the output enough to act on it. Those questions tend to produce better systems. At Nano Dimension and Additive Flow I led the development of simulation and digital twin platforms for industrial additive manufacturing — surrogate models replacing expensive physical qualification loops, agentic pipelines running R&D workflows autonomously, AI layers turning months of iteration into days. Across those programmes the outcomes were concrete: £10M+ in R&D value, qualification costs down 40%, decision cycles that used to take hours running in seconds. Through Gouvea Applied Innovation I now work with technical founders and R&D leaders trying to do something similar — build intelligent systems that hold up in production, remove the bottlenecks costing them the most, and give their teams genuinely better signal to work from. Alongside that I build outbound and lead generation infrastructure for B2B companies, particularly those selling into technical or industrial markets where generic automation tends to fall flat. It's a different application of the same underlying skill: designing systems that find the right people, say the right thing, and run without constant intervention. 📩 Open to collaborations on: ✔ Agentic AI systems for R&D, simulation, and engineering workflow automation ✔ Digital twin platforms and surrogate model development ✔ AI strategy and implementation for deep-tech and advanced manufacturing ✔ B2B lead generation infrastructure for technical and industrial markets ✔ Go-to-market support for early-stage deep-tech companies

I’m a mathematical physicist and research assistant pursuing my PhD at the University of Belgrade. My work combines theoretical research, university teaching, and STEM content development. My research focuses on theoretical condensed-matter physics, particularly symmetry-protected topological phases and bulk–boundary correspondence, using group theory, symmetry analysis, and transfer-matrix methods. As a Teaching Assistant, I guide students in Symmetry in Physics, a Mathematica-based course that connects abstract symmetry principles with computation. I’ve also spent five years at Quizlet, writing and moderating thousands of physics and math problems, and three years at Educational Center "Korak Napred", preparing Olympiad students—several of whom became medalists—and tutoring across all levels. How I can help • Research and technical summarization • Physics and mathematics content creation • Tutoring and concept explanation • Academic and LaTeX formatting Whether your project involves research, content development, or structured educational writing, I look forward to helping you bring precision and clarity to your work.

I’m a professional video editor, motion graphics artist, and photographer with more than 5 years of experience working with Premiere Pro and After Effects for video editing and motion graphics, and Photoshop, Lightroom, Illustrator, and GIMP for image and illustration preparation. I focus on delivering high-quality results with a fast turnaround time, depending on the project scope. My services include video editing, motion graphics, photo editing, image processing, logo animation, and visual content preparation. In addition to my creative work, I hold a Ph.D. in Physics, specializing in microelectronics and solid-state electronics, with international experience working at interdisciplinary research institutes. I have experience with scientific and analytical software such as Wolfram Mathematica, MATLAB, and OriginLab, as well as programming languages including C++ and Python. I also have extensive experience writing and editing scientific papers. I’m fluent in English, Portuguese, and Russian, and I can also help with translation, editing, and proofreading, especially for technical and scientific texts. Thanks!
