Featured AI Engineering projects

Selected for AI Engineer / Applied AI Engineer roles in Thailand. Demos clearly distinguish deterministic fixtures from optional real-model inference.

Project Engineering evidence Explore
Receipt AI Expense Tracker Thai/English document extraction pipeline, financial reconciliation, human review, privacy-aware local storage; live public demo uses Groq Qwen vision with Gemini as a configured fallback, with per-IP rate limits and user-confirmed local saving. Repo · Demo
Customer Support RAG Triage Agent Bounded retrieval, typed LangGraph workflow, grounding checks, evaluation, and human-action routing; public demo uses synthetic records and deterministic generation. Repo · Demo
EvalOps Lab Retrieval evaluation, versioned evidence, regression policies, CI gates, and failure analysis. Public console displays sanitized synthetic evidence, not live model execution. Repo · Evidence
VeriClaim AI Evidence-driven claim verification, bounded agent workflow, provenance, and reproducible evaluation. Hosted demo is fixture-only. Repo · Demo
OpenDQ Observatory Operational data quality, drift monitoring, incidents, lineage, deterministic RCA, and bounded AI explanations. Repo · Live
Thai Review Sentiment Intelligence Thai NLP model training, reproducible splits, baseline comparison, macro-F1 evaluation, and FastAPI inference. Repo · Demo

New ML / Time-Series (synthetic-only, interactive hosted demo): Industrial Predictive Maintenance AI (Live) — causal sensor features, asset-and-time holdout, model vs heuristic baseline, and reproducible tests. These synthetic scores do not establish real-world effectiveness.
