What I'm looking for

I’m looking for a team where I can build immersive, high-performance WebGL and Unity experiences—especially medical imaging visualization—while collaborating cross-functionally to refine user experience and maintain standards-compliant, production-ready software.

I’m a results-driven Software Developer with 7+ years of experience across WebGL medical imaging, AR/VR development, game development, and cross-platform applications. I’m proficient in C#, Unity 3D, WebGL, Three.js, and React Native, and I’m passionate about delivering immersive, high-performance digital experiences.

In my current role, I develop WebGL-based volume rendering algorithms for medical imaging data (DICOM and NIfTI), optimize WebGL2 rendering performance and quality, and integrate interactive tools like slicing, segmentation, and measurement. I collaborate with medical imaging experts, QA, and engineering teams, and I document development processes and technical specifications to support reliable, standards-aligned visualization.
