Profile

About
Me

Software Engineering foundation, AI specialisation.

我是 Sam Lv，是广东的软件和人工智能工程师，在 Python 和 Java 中构建生产后端系统、REST API 和 AI 应用管道方面拥有 5 年以上的专业经验。

我在澳门大学完成了人工智能理学硕士学位，专攻 LLM、RAG、智能体工作流程与可解释人工智能。参与过多项工程落地项目，覆盖智能体开发、全栈系统搭建与算法工程化，将 RAG 管道、LangGraph 和 XAI 技术落地到多类型文本、图像与音频业务数据中。

I'm exploring 2027 graduate opportunities in AI Agent engineering, applied algorithms, and full-stack development. I enjoy turning an ambiguous problem into a system people can understand and use.

Capabilities

What I
Build

I combine a strong software engineering foundation with modern AI work. My focus is practical delivery: clean systems, reliable integrations, and AI features designed for real product workflows.

AI-Enhanced Applications

Build intelligent features that improve user experience and decision-making, from prediction to automation, designed for real product workflows.

NLP & Conversational Systems

Design chatbots and language-driven workflows with structured intent handling, retrieval-based answering, and analytics-ready integration into backend systems.

Computer Vision Solutions

Develop image-based pipelines for classification and analysis with a focus on evaluation, robustness, and practical deployment considerations.

Backend & API Engineering

Build scalable backend services and REST APIs with clean architecture, strong validation, and maintainable integrations for product environments.

Data Pipelines & Feature Preparation

Prepare data for ML and analytics — cleaning, transformation, feature engineering, and reproducible processing suited for iterative model development.

Model Evaluation & Explainability

Validate models with appropriate metrics and error analysis, and apply explainability techniques to improve trust, interpretability, and iteration speed.
