Pakakorn Sitthisak

I've built pricing microservices and machine-learning production workflows at Agoda, including optimized price and deal calculations, offline model evaluation infrastructure, and Spark-based pipelines for large-scale data.

At Balerion, I developed scalable web applications with ReactJS and Go, delivering reliable backend services and production-ready features across frontend and backend components. Previously, as Head of System Development at Central Food Retail, I led teams building B2B e-commerce mobile applications with Flutter and Python/Flask and deployed scalable cloud solutions on GCP.

I'm currently expanding my AI/ML engineering work through hands-on LLM applications, RAG, AI agents, deep learning, and recommendation systems. My projects include an AI document assistant, a customer-support agent with tool calling and memory, and an end-to-end movie recommendation platform using collaborative filtering.

I bring more than 10 years of experience across Go, Python, TypeScript, distributed systems, cloud infrastructure, data engineering, and machine-learning deployment.
