Tien Dat Do

Senior Associate, Operations — AI Automation & Chatbot

• Merchant Onboarding Agent: Own the document agent that turns merchant onboarding uploads — business registrations, contracts, ID cards — into a structured KYC record for the operations team.
• Deterministic Quality Gate: Designed the accept / review / reject verdict and escalation path in code rather than in the model, restricting the LLM to extraction only — removing the failure mode where a model confidently asserts a field it could not actually read.
• Shipped v3 → v6: Each fixed bug is locked in by a test that reproduces it against the previous version, so a later release cannot reintroduce it.
• Operable Rollout: Versioned releases with a documented rollback path and a first-run verification checklist for each deploy.

Internal Platform Specialist (Internal AI Chatbot)

• AI Chatbot Development: Lead end-to-end development of the team's custom chatbot — prompt engineering, knowledge base management, hybrid RAG (KNN) for improved accuracy, and message tracing for debugging.
• Claude Skills Development: Build custom Claude Skills to automate daily tasks for team members, driving the company-wide transition toward an AI-agent ecosystem.
• Operational & Data Analysis: Execute deep-dive analyses on CSAT metrics and suspicious ticket activities during major promotional campaigns.

Assistant to Directors

• AI & Data Engineering: Built lightweight ETL/ELT pipelines in Lark Base, Airtable, and Google Apps Script to standardize data from POs, supplier quotes, and shipment trackers.
• AI Agent Deployment: Deployed a custom AI agent (NexAI) to automate email triage — routing supplier updates, techpack submissions, and client communications.
• Document Parsing Pipeline: Engineered an AI pipeline that extracts line-item data from unstructured PDF invoices and loads it into centralized Google Sheets.
• Financial Reconciliation: Automated invoice comparison against agreed vendor rates, instantly flagging billing discrepancies.
• Business Process: Mapped procurement → production → QC → shipment workflows, defined SLAs, and set alert thresholds to cut delays and rework.
