Da Nang, Vietnam - 6:48 pm local time
I am a Senior Full-Stack Engineer with 10+ years of experience designing, building, scaling, and operating SaaS platforms, fintech products, AI-powered applications, and cloud-native systems.

For the past 5 years, I have been working at Money Forward, one of Japan's leading fintech companies, where I contribute as a Full-Stack Engineer and a key player in platform engineering initiatives. My responsibilities span application development, cloud infrastructure, CI/CD automation, Kubernetes operations, performance optimization, disaster recovery, observability, and scalable system architecture.

Over the last 2 years, I have also focused heavily on AI-powered solutions, helping clients build applications using OpenAI models, GPTScript, AI agents, workflow automation, and LLM integrations.

My strength is not only building software but also ensuring that systems remain scalable, reliable, observable, and cost-efficient in production environments.
