About

Professional summary

I am a Senior Full-Stack Engineer with more than seven years of experience building enterprise web applications, AI-powered products, and cloud-native systems. I have delivered solutions for financial services, healthcare, and enterprise clients across the United States and Asia-Pacific.

My core development stack includes TypeScript, React, Python, Node.js, and AWS. I am experienced in leading projects from technical discovery and architecture through production deployment, post-launch support, and continuous improvement.

I build AI-enabled workflows using LLM integrations, RAG pipelines, OpenAI API, LangChain, and pgvector. My work includes document search, automated summarization, and intelligent triage systems that reduce manual analyst effort.

I design scalable backend systems and event-driven microservices using AWS services such as ECS, Lambda, SQS, RDS, and S3. I also establish reliable delivery processes with Docker, Terraform, GitHub Actions, automated testing, and structured code reviews.

I enjoy partnering directly with stakeholders to translate complex business needs into clear engineering specifications. I mentor engineers, lead sprint planning and technical discovery, and apply disciplined CMMI Level 5 quality practices while maintaining product delivery speed.
