I’m a backend software engineer with 5 years of professional experience in Python, and a recent MSc graduate in Data Analytics and Artificial Intelligence from Hong Kong Baptist University.

I specialize in building scalable backend systems, crafting clean APIs (REST & GraphQL), and working with PostgreSQL, MySQL, and other relational databases. I've designed and delivered production-ready services—from permission systems and OAuth2 integrations to internal SDKs that streamline team workflows. I value clean architecture, coding standards, and enjoy mentoring junior developers.

I'm actively transitioning into LLM Application Engineering, MLOps, and ML Engineering, where I can combine my backend expertise with applied machine learning and AI deployment.

As part of my MSc journey, I completed projects on facial expression recognition, applying:

• StyleGAN2-ADA for synthetic data generation
• ResNet, EfficientNet for classification
• UMAP, t-SNE for visualization
• Training pipelines built with PyTorch Lightning and tracked using Weights & Biases (wandb)

I’m also exploring LLM-powered systems with LangChain, Transformers, and model deployment using TorchServe, FastAPI, and Docker.

• Languages: Python (Primary), SQL (Working Proficiency)
• API: REST, GraphQL, FastAPI
• Frameworks: FastAPI, Flask, Django, PyTorch Lightning, LangChain
• ML/AI: Transformers, LoRA, RAG, CNNs, GANs, Diffusion Models
• MLOps & DevOps: Docker, TorchServe, Triton, MLflow, CI/CD, wandb, Git
• Tools: FAISS, TensorBoard, UMAP, t-SNE, PCA
• Cloud & Deployment: Heroku, HuggingFace Hub, Dockerized bots, scalable microservices

• Native Chinese speaker
• Fluent in English
• Passionate about cross-language expression and grammar insights

I’m committed to fitness and mental clarity, I believe that physical health sharpens discipline and focus.

I enjoy solving problems through systems thinking and thrive on connecting the dots between engineering, data, and real-world usability. Whether it’s debugging backend bottlenecks or optimizing training pipelines, I aim to build solutions that are both elegant and practical.
