About

Professional summary

I am a Senior AI Engineer specializing in scalable, high-performance AI applications. My core expertise includes machine learning, deep learning, computer vision, natural language processing, large language models, AI agents, model training, and inference optimization.

I design and deliver production-ready AI systems, including object detection, face recognition, OCR, vision-language applications, RAG systems, and multi-agent workflows. I have experience building complete MLOps pipelines for data annotation, training, evaluation, experiment tracking, deployment, and monitoring.

I combine AI engineering with a solid backend development background in FastAPI and Django. I build scalable APIs, asynchronous services, data pipelines, and cloud-integrated applications that bring AI capabilities into practical software products.

I have worked on enterprise AI consulting and internal productivity products, helping teams adopt generative AI for code generation, email automation, voice-based interview simulation, technical support, and knowledge retrieval.

I am passionate about solving complex technical problems with GPU-accelerated computing and high-performance platforms. I enjoy optimizing training and inference workloads using CUDA, mixed precision, TensorRT, Triton Inference Server, and modern LLM serving frameworks.

I am experienced in collaborating with international clients and translating technical requirements into tailored AI solutions. I aim to build reliable, efficient, and impactful AI products that can scale in real-world environments.

Career history

AI Engineer Sun Asterisk

Researched and engineered an AI-Driven Development harness integrating OpenAI Codex and Claude Code to automate code generation, streamline development workflows, and improve engineering productivity.

Built internal AI productivity features, including automated email generation and a voice-based interview simulation platform using conversational AI frameworks such as Vapi. Provided technical AI consulting to enterprise clients in US and European markets, gathering requirements, designing tailored GenAI architectures, and advising on integration into existing software ecosystems.

AI Engineer Saigon Technologies

Designed scalable AI systems for multi-camera object detection using FastAPI, Kafka, Triton Inference Server, TensorRT, and asynchronous processing. Built end-to-end training and evaluation pipelines for 100+ class YOLO models with Label Studio and MLflow, achieving 0.56 mAP.

Developed face similarity search using MagFace, virtual eyelid try-on algorithms, RAG-based internal chatbots, multi-agent customer support systems using LangChain and LangGraph, and VLM-based product search using Grounding DINO and CLIP. Built interactive 3D avatar experiences with Whisper, GPT-4o mini TTS, and GPT-5.

Optimized transformer workloads by developing a fused softmax CUDA kernel and applying FP16, cuDNN, and TensorRT optimizations, reducing end-to-end latency by 30%. Deployed high-throughput document retrieval and inference services using vLLM and Qwen Embedding 8B.

AI Engineer VJ Technologies

Developed and deployed backend AI services for an OCR and computer vision platform using Django, Nginx, OpenCV, Google Vision OCR, and GPT-based processing. Built scalable APIs for production document intelligence workflows.

Owned the implementation of Japanese card information extraction pipelines, transforming unstructured OCR results into structured JSON and reducing manual data-entry effort by 50%. Researched perspective normalization for documents and cards, sketch-to-Excel conversion, and automated post-processing workflows.

Fine-tuned transformer-based Japanese handwritten OCR models, including TrOCR and Manga OCR, on domain-specific data. Conducted benchmarking using CER and WER, achieving 15% CER and 27% WER.

AI Engineer Freelance

Built document intelligence and AI research agents that ingest PDFs, images, and structured files. Developed collaborative LangGraph multi-agent research workflows, Milvus-powered retrieval, FastAPI backends, and automated generation of reports, charts, and documents.

Developed AI-enhanced e-learning, real-time event tracking, and technical support automation platforms. Delivered full-stack applications using Django, React, FastAPI, PostgreSQL, Firebase, AWS, Redis, Celery, Supabase, n8n, and CI/CD pipelines.
