Yi-Hsiang (Sean) Ho | 何義翔
I'm a Computer Science student passionate about AI/ML, Systems Engineering, and Software Development. I recently interned at Appier as a Backend Engineer and I have extensive experience in full-stack development, Linux system administration, and computer vision research.
Experience & Education
Projects
FastAPI, PostgreSQL, Docker
A labor matching platform for underserved regions. Architected and implemented a RESTful API backend and database to power a Cloud Phone-based platform.
C, Assembly
Developed a 64-bit multitasking OS kernel from scratch. Engineered memory management, UART drivers, and a multi-tasking scheduler.
C++, Python, pybind11
Engineered a cross-language faster 2D convolution solution using Fast Fourier Transform.
Python, OpenCV, PyTorch
Optimized Zero-DCE, a low-light enhancement approach, to address both over- and under-exposure challenges. Achieved a 144% improvement in PSNR and 54.5% in SSIM.
Python, PyTorch
Implemented computer vision models (ResNet, Faster R-CNN, Mask R-CNN, PromptIR) for classification, segmentation, and restoration. Optimized performance using data augmentation and cross-validation.
Python, PyTorch, NumPy
Implemented seven labs covering backpropagation in NumPy, UNet segmentation, MaskGIT inpainting, conditional VAE video prediction, DQN variants, conditional diffusion, and A2C/PPO. Reached 0.934 Dice, 29.1 FID, and a Pong score of 19.95.
C++
A CLI game utilizing the concept of OOP. Features include character occupations, battle mechanics, and file saving/loading.
