Chan Kim (Hitbee-dev)

A Software Engineer who bridges the gap between complex AI research and efficient, real-world systems. I build solutions that are not just accurate, but robust and scalable.


Key Experiences & Impact

πŸš€ Performance Tuning: Real-time ViT on Edge AI

I tackled the challenge of deploying a heavy Vision Transformer (RT-DETR) on a resource-constrained NVIDIA Jetson device, achieving a 2.8x inference speedup (9 β†’ 26 FPS). This optimization was a key factor in securing a β‚©12B government contract and proved the commercial viability of using advanced ViT models in edge environments.

πŸ—οΈ System Architecture: AI Development Productivity x10

To resolve a critical development bottleneck, I architected 'PIPER', a standardized, asynchronous system for large-scale AI development. This system dramatically reduced data processing time from 4+ hours to under 5 minutes and streamlined new model integration, boosting overall team productivity.
