Stateful agent workflows for executive tasks, news, meetings, email and document search.

LangGraph · FastAPI · PostgreSQL · Microsoft Graph · Docker

• Developed a stateful multi-agent assistant routing requests across task management, news briefings, meeting summaries, email drafting and document search.
• Implemented LLM relevance filtering for news and extracted report structure from sample PDF/DOCX files so generated briefings follow the requested format; supported PDF and DOCX export.
• Worked on PostgreSQL checkpoint connection lifecycle, async task persistence and deadline/status handling; implemented human-in-the-loop confirmation flows for Teams/Planner integration.

A bilingual iOS self-reflection product with streamed AI responses and a privacy-conscious backend.

Flutter · FastAPI · PostgreSQL · Redis · RevenueCat

• Developed a bilingual iOS product and async Python backend with provider-agnostic AI responses streamed over server-sent events (SSE).
• Implemented Redis-backed cost reservations and cancellation cleanup to control concurrent generation spend and release resources after interrupted requests.
• Worked on subscription webhook reconciliation and account-merge consistency, alongside encrypted private text and privacy-conscious telemetry; prepared release checks and local validation.

A streaming chatbot with conversation memory, prompt tracing and PII anonymization.

OpenAI / Vertex AI · MongoDB · Gradio · LangSmith · Microsoft Presidio

• Built a streaming chatbot with MongoDB-backed conversation memory and configurable bot behavior; added LangSmith prompt versioning and tracing.
• Integrated Microsoft Presidio to anonymize personally identifiable information before sending content to the LLM.

New blog project that heavily uses ChatGPT and Cursor. As a back-end enthusiast who's no fan of CSS, I relied on these AI tools to help shape both the design and content. From styling advice to layout tweaks, the entire process was an AI-driven collaboration—and it turned out surprisingly well!

Next.js · React · TypeScript · Tailwind CSS · ChatGPT · Cursor

• Used AI-assisted iteration to build and refine the site: implementation in Cursor, browser review, screenshot-based feedback and targeted UI adjustments.
• Built a personal publishing and portfolio site with searchable blog posts, topic filters, light/dark themes and responsive layouts.
• Connected structured profile data to the About page and a reproducible PDF resume, keeping the full website portfolio separate from the CV selection.

Led the development of a consultancy chatbot for SARS-COVID-2 patients, providing symptom assessment and self-care advice. Implemented machine learning models (KNN, SVM) for Intent Classification and developed a Named Entity Recognition system using PhoBERT and CRF.

Python · FastAPI · Vietnamese NLP · scikit-learn · MongoDB

• Separated natural language understanding, dialogue management and response generation, with structured intent/entity results passed between stages.
• Used TF-IDF features with KNN and SVM classification; maintained conversation context to support follow-up questions rather than isolated one-turn replies.
• Connected the conversation API and frontend, with stored dialogue state and structured response options. This is a historical engineering project; no clinical validation or deployment scale is claimed.

A reusable AI application backend organized around specialized experts, configurable model components and interchangeable conversation memory.

FastAPI · LangChain · RAG · Dependency injection · MongoDB · Docker

• Separated expert behavior from shared model, memory, embedding and vector-database interfaces to make new workflows easier to add.
• Implemented a document retrieval expert with PDF loading, semantic chunking, document metadata and synchronous/asynchronous indexing paths.
• Organized reusable application setup and containerized development around the same backend foundation used for conversational applications.
