NLP systems, AI agents and the projects behind them

Products first: a medical speech translation prototype, two AI agent apps in development, and two live systems I managed. Below them, every research and training project I have worked on.

Research application

Medical speech translation

Built with the VinUni medical MT group.

Vietnamese–English Medical Speech Translation

My role
Project Coordinator
Problem
Doctors and patients who do not share a language struggle with spoken communication, especially when the conversation is full of medical terms.
Approach
The VinUni medical MT group chains Vietnamese speech recognition with Vietnamese–English medical machine translation in a real-time pipeline.
What it shows
  • A team product, not a solo one: Nguyen Giang Son built and hosts the MedComms demo on a server, running a speech-to-text (STT) model and a text-to-text translation model fine-tuned on the project's data.
  • Real-time pipeline: ASR → medical MT, served as a public web demo.
  • Built on the group's own data: MedEV (translation) and ViMedCSS (code-switched medical speech).
Status
A working team research prototype for clinical and educational settings. It is a research tool and has not been clinically validated.

AI agent apps

Built with AI coding agents (Claude Code, Codex, Orca): I design, specify, test and review; the agents write most of the code.

No More Later · AI Priority Agent

In development
Role fitLLM / Agentic AI Engineer · AI Engineer
My role
Product owner & architect · AI-assisted build
Problem
To-do lists grow faster than anyone can work through them, and deciding what matters today takes more effort than the tasks themselves.
Approach
Turns tasks written in plain language into a daily plan: picks a Top 3, sorts work on an Eisenhower matrix, explains each priority, and replans when deadlines change. Every AI change waits for the user's approval.
What it shows
  • AI-assisted development with Claude Code and Codex, coordinated in Orca: I set architecture, specs and acceptance criteria, gated changes on tests and reviewed every merge; the agents wrote most of the code.
  • Multi-provider LLM gateway: OpenAI, Anthropic, Gemini and local Ollama, with cost-aware routing, fallbacks and a circuit breaker.
  • Prompt-injection test suite across every extraction workload; model output validated against JSON schemas.
  • Human-in-the-loop: assistant and replanning outputs are stored as proposals the user accepts or rejects.
Show 4 more
  • Per-user token budgets with atomic reservations; every inference logged with tokens and cost.
  • Privacy controls: per-user egress policy for cloud models, BYOK keys, SSRF-guarded outbound calls.
  • Semantic search with pgvector next to PostgreSQL full-text search; MCP server exposing task tools to other agents.
  • 160+ test files (Vitest), including database tests.
Status
A working monorepo with web, desktop and mobile clients, built with AI coding agents under human review. Public deployment is coming soon.

Togo Todo · AI Shared Planning Agent

In development
Role fitLLM / Agentic AI Engineer · AI Engineer
My role
Product owner & architect · AI-assisted build
Problem
Plans shared between several people, such as a trip or a joint project, end up scattered across chats, notes and maps.
Approach
A shared planning workspace with a chat agent: it reads a request, recommends activities, places and checklists, and only changes the shared plan after a member confirms.
What it shows
  • AI-assisted development with Claude Code and Codex, coordinated in Orca: I set architecture, specs and acceptance criteria, gated changes on tests and reviewed every merge; the agents wrote most of the code.
  • Multi-agent orchestration: an orchestrator routes each turn through language, ingest, RAG, places, policy, guardrail and mutation agents.
  • Hybrid RAG: pgvector similarity and full-text search merged with Reciprocal Rank Fusion.
  • Human-in-the-loop: every change becomes a pending action, validated again with Zod at confirm time.
Show 3 more
  • Agent observability: runs and spans stored in the database and traced in LangSmith; per-call LLM usage tracked.
  • Conversation memory per shared workspace; models via OpenRouter and local Ollama.
  • 89 test files: Vitest unit tests and Playwright end-to-end tests.
Status
Running locally with demo projects, built with AI coding agents under human review. Public deployment is coming soon.

Institutional systems

Systems I managed from planning to launch with software partners. Both are live.

Green Transformation M&E System · Khanh Hoa

Live system
Role fitProject Manager
My role
Project Manager
Problem
Provincial departments need one place to monitor and evaluate progress on green transformation.
Approach
A website and mobile app for monitoring and evaluation, built with the software partner Bamboo Software (co-PI).
What it shows
  • 10 provincial departments involved.
  • PIs: Dr Thuy Bui, Nhu Vo and associates, at the Smart Green Transformation Center (GREEN-X), VinUniversity.
Status
Delivered Nov 2024 – Nov 2025 with 10 provincial departments of Khanh Hoa. Funded by VinUniversity.

My role
HCMUE Team Leader
Problem
Teacher training under the Enhancing Teacher Education Program (ETEP) needed an online learning platform at HCMUE.
Approach
Built and rolled out the university's virtual learning environment with ACP Computer Training & Consultancy (Singapore).
What it shows
  • Funded by the Ministry of Education and Training and the World Bank.
  • HCMUE team: Dr Long Le, Ms Van Nguyen and Nhu Vo (team leader); ACP co-PIs: Alan Poh, Kelvin Lee.
Status
In use at HCMUE. Oct 2018 – Feb 2020; certificate awarded to the team leader for supporting the complete system.

Planned

Ideas I plan to build next.

  • Coming soon
    Email Management AI Agent

    An LLM workflow that reads email, pulls out what matters, and drafts summaries and next actions for the user to review.

  • Concept
    LLM Translation Agent

    A workflow that moves from source text and instructions to an LLM draft, then to a terminology check and a review step, so errors are caught before the text is used.

  • Concept
    Speech Translation Agent

    Chain speech recognition, machine translation and LLM post-processing into a general-purpose speech translation assistant, extending the medical prototype beyond healthcare.
