Description

Hi, I’m Tien, a Senior AI Engineer and Software Architect with experience designing and building enterprise AI systems.

My work focuses on Agentic AI, Retrieval-Augmented Generation, LLM evaluation, document intelligence, and production-ready AI pipelines. I combine data science, AI engineering, and software architecture to turn GenAI prototypes into reliable, scalable, and maintainable solutions.

I’m particularly interested in applying trustworthy enterprise AI to complex, knowledge-intensive, and regulated industries, including LegalTech, banking, financial services, and insurance.

I’m always happy to connect with professionals working in AI, data science, software engineering, architecture, and digital transformation to exchange ideas, share experiences, and explore opportunities for collaboration.

I'm an AI Engineer and Full Stack Software with over 7 years of experience building intelligent systems using machine learning, NLP, modern AI technologies, React/Angular.

🔹 Current focus:
I work on large language models (LLMs), multi-agent systems, and generative AI — developing chatbots, recommender systems, and real-time applications that scale. I enjoy bridging research and production, turning cutting-edge models into practical solutions.

🔹 Technical strengths:
+ LLM fine-tuning, prompt engineering, and orchestration (LangChain, LangGraph, OpenAI SDK)
+ ML pipelines, model deployment, and data engineering with Python
+ Full-stack and backend development (Python, Java, JS/TS, Angular/React)
+ Experience with distributed systems, CI/CD, and cloud-based architectures

🔹 Approach:
I thrive in cross-functional teams, working closely with product, engineering, and research. I enjoy solving real-world problems through experimentation, fast iteration, and thoughtful system design.

I'm always learning and excited to collaborate with others in the AI/ML space.
Let’s connect if you’re building something impactful or just want to talk about LLMs and the future of AI 🤝
