At WPH Digital, I build AI-powered document processing features that turn healthcare and insurance documents into structured digital outputs. I use JavaScript, Python, React, and Next.js to connect AI systems to practical business workflows.

I've developed OCR and LLM extraction workflows for 20+ document fields, including patient details, hospital information, invoice totals, medication tables, and insurance data. By automating extraction, JSON formatting, and OCR correction, I reduced manual extraction effort by an estimated 40–60% during testing.

I integrate AWS services including Cognito, S3, IAM, API Gateway, Lambda, DynamoDB, RDS, Amplify, and EC2 for authentication, storage, APIs, databases, deployment, and ML workloads. I also improve reliability through JSON validation, OCR cleanup, uncertainty handling, and domain guardrails.

My projects include an NLP-based ethics review platform and an inspection OCR system for Thai healthcare and insurance documents. I hold a Computer Science degree specializing in Intelligent Systems and have trained and evaluated models on more than 8,000 labeled sentences.
