Summary
🤩
Rockstar🎓
Top SchoolMiguel Castaño is a software engineer blending five-plus years of high-performance engineering and applied research to deliver production-ready systems in rendering, computer vision, and computational imaging. He built a vectorized radiative transfer solver and integrated differentiable rendering with ML for satellite and scene reconstruction work at EPFL, contributions that fed into widely used projects like Mitsuba 3. His open-source tools—VERIV and MiTransient—have thousands of users and academic recognition (Best Poster ICCP 2024), showing an ability to package research into practical developer tools. Comfortable across LLVM/CUDA backends, PyTorch models, and C++ production code, he bridges low-level optimization and algorithmic innovation. Now based in Lausanne and working at Meta via Qualitest, he seeks industry roles that value rigorous research translated into scalable, user-focused software.
