Senior AI Engineer / Machine Learning Engineer 

  • Turned a 3-hour AI prototype into the production multi-source data collection pipeline that powers Penny's seasonal recipe-matching system.
  • Led the production rollout of multimodal hybrid search for the store-employee assistant, cutting document lookup times from hours to under 5 minutes. Queries route through a Google ADK agent-to-agent orchestrator using MCP tools, Kubernetes, and LangSmith.
  • Built a few-shot RAG service using LangChain, Qdrant, and FastAPI that generates personalized coupon copy from master-data offers, replacing weekly manual copywriting.
  • Built a multi-agent GenAI system that matches weekly product offers with seasonal recipes, providing explanations for each match and saving marketing teams hours of manual work every week.
  • Introduced spec-driven development practices across the company through technical sessions attended by nearly a thousand internal developers across Europe

Semantic Product Search Engine 

Freelance 
Freelance 
  • Evaluated candidate search engines and chose Meilisearch for hybrid semantic and keyword search across Thai and English, keeping hosting costs low and avoiding custom search infrastructure.
  • Built a PostgreSQL to Meilisearch sync pipeline using logical replication and MeiliBridge. Product index updates take under a second, with no changes required in the client application.
  • Tuned search relevance before launch using ranking rules, typo tolerance, text embeddings, type-ahead queries, and faceted filters.
  • Contributed compatibility patches to the open-source MeiliBridge Rust repository to support the production rollout

Credit Default Prediction

Freelance 
Freelance 

  • Built an MLOps pipeline for credit default models with automated data cleaning, MLflow experiment tracking, blue-green model selection, and retraining orchestrated with Prefect.
  • Tuned profit-based decision thresholds, showing a 30% simulated profit increase on out-of-sample test data compared with the existing policy.
  • Deployed a FastAPI service for low-latency default predictions, with automated retraining as new repayment data arrived

Customer Feedback Classification 

Freelance 
Freelance 

  • Cut customer case resolution time by 18% with a Thai-language classifier that routes incoming feedback to the correct service team.
  • Retrieved similar labeled examples from ChromaDB using OpenAI embeddings as few-shot context, raising classification accuracy without retraining models.
  • Packaged the classifier as a Dockerized FastAPI service so the client team can add training examples via CSV uploads without redeploying

Data / Machine Learning Engineer
  • Built a reusable AWS MLOps starter kit with Terraform-provisioned SageMaker templates and MLflow tracking, speeding up proof-of-concept delivery across client engagements.
  • Deployed the starter kit across client engagements, including an LLM-based PDF summarization service with LangChain and a PyTorch computer vision model detecting defects on steel production lines.
  • Built an automotive predictive-maintenance pipeline in PySpark, covering data extraction, feature engineering, and a Streamlit dashboard that helped lower maintenance costs.
  • Delivered a long-stalled ETL project in half the estimated time by implementing missing domain equations and reworking the data-processing workflow
