Software engineer with 9 years shipping production systems, now building applied AI. MSc in AI for Business Analytics (KMITL, 2025) and first author of an IEEE paper on Thai/English sentiment analysis. I bring the engineering side AI work needs: backend services, Docker/Kubernetes deployment, and platforms real users depend on.
- Now — Senior Developer at WHA Group: digital signature, document and back-office platforms on Docker, Kubernetes and Huawei Cloud.
- Building — offline OCR for Thai legal documents with a local vision-language model, and an LLM-curated engineering knowledge base.
- Open to — AI Engineer / AI Application Engineer roles, hybrid, Bangkok and Samut Prakan.

Offline Thai Legal-Document OCR · ongoing Scanned Thai contracts → Markdown and searchable PDFs, fully offline: docTR line detection → Typhoon OCR 1.5 (2B Thai VLM) → line-level text layer. Evaluation harness on a verified gold set (CER, WER, flag rate, search recall, speed) with pass rules set before each run. |
