Freelance AI engineer. I take models from notebook to production: fine-tuned NLP, LLM assistants, and the event-driven APIs around them.

About
I'm a software engineer in Ho Chi Minh City, finishing a Software Engineering degree at HUTECH, where I was named an Outstanding Student for 2024–2025.
My work sits where AI meets backend engineering: training and serving models, then building the services that keep them reliable. Before freelancing I built REST APIs for a clinical management platform as a backend intern at Amethyst Medical Vietnam.
Services
Three ways I usually help. Each one is backed by a system I've already shipped.
Text classification, content moderation and LLM assistants — trained on your data or built on an API, served fast.
Event-driven services that keep data consistent under load, with auth, caching and failure handling built in.
From idea to a deployed product: web app, backend and AI in one build, with one person accountable.
Selected work
Case study · Social platform · 2025
Toxic comments in Vietnamese slip past English-first filters. I fine-tuned PhoBERT on scraped YouTube and TikTok comments and wired it into a microservices platform so every comment is checked without slowing the feed.
Product demo · 3:24
Backend · E-commerce
REST backend for an online store: catalog, cart, orders, flash sales that don't oversell, and VNPay payments.
Lab · Linux desktop
Linux port of the open-source FxSound (AGPL-3): a PulseAudio passthrough backend, low-latency tuning and .deb packaging.
Process
A short call to understand the problem. You get a written scope, milestones and a quote.
Weekly demos and a shared repo, so you see progress, not surprises.
Deployed to your infrastructure with Docker, CI/CD and handover docs.
Fixes and improvements after launch, as agreed in the scope.
Contact
Share a few details and I'll reply with questions or a proposal, usually within one business day.
