Software Engineer with ~5 years of experience building scalable web applications and data-driven platforms. I specialize in backend development with Node.js and AWS, with a strong focus on designing event-driven architectures powered by RabbitMQ, Redis, and BigQuery.

• 🔭 Most recently built a real-time user behavior analytics platform (Google Analytics–style) that lets marketers capture, analyze, and optimize user engagement across websites.
• 🤖 Shipped AI-Intent and AI-Insight — LLM-powered features for record-level enrichment and recurring report analysis, backed by multi-provider LLMs, BigQuery, and AWS Lambda/SQS/DynamoDB.
• 🧩 I care about the unglamorous parts — throughput, idempotency, and observability — that make products feel instant and never go down.
• 🌱 Currently going deeper into distributed systems and looking for the next hard problem at scale.
• 📍 Based in Nha Trang, Vietnam · open to select opportunities.
