Abstract
The entry materials for iOS can be described as flooding on the Internet. If you have a computer foundation and want to learn iOS quickly, you can do it easily with making a few user interfaces. However, after the enthusiasm for mobile entrepreneurship receded, the ability requirements of iOS developers have became higher and higher. When an beginner developer wants to become a better iOS developer, he will find that the Internet information is too trivial, and the quality of the information is difficult to distinguish. Ones often gets confused about how to improve himself and where to find good learning materials. This is the problem this book tries to solve. From the perspective of senior engineers, we find articles that we believe are of high quality and helpful to improve the technical level of iOS developers. This book is not a systematic study course, but an advanced supplementary book that broadens your horizons, so that readers can access things that are not commonly used in their work, open the door to your interests, and enhance your curiosity, this is the book original intention.

Senior ML Engineer

I am a research-oriented machine learning systems engineer working on foundation model infrastructure, closed-loop evaluation and optimization systems, and scalable AI platforms. My work focuses on building reliable Model-as-a-Service and Harness-as-a-Service platforms that connect data, training, inference, evaluation, and feedback loops into measurable, continuously improving AI products.

My recent work centers on Model-as-a-Service platforms and high-performance LLM inference. I develop serving infrastructure with vLLM and SGLang across model runtime integration, scheduling and continuous batching, KV-cache and memory management, distributed execution, observability, and reliability. This systems work is closely connected to my research on distributed disaggregated inference, preference optimization, instruction-tuning data selection, multimodal evaluation.

My broader research centers on reinforcement learning infrastructure and reinforcement learning optimization algorithms for scalable AI systems. I am interested in how policy optimization, reward modeling, preference learning, offline RL, simulation environments, distributed rollout systems, and automated evaluation harnesses can be engineered together to improve model behavior. My goal is to build frontier AI systems that learn from feedback efficiently, evaluate progress rigorously, and remain dependable when deployed at scale.
