Hi, I'm Hoang Le Duc πŸ‘‹

AI Engineer Resident @ Qualcomm Β· Spatial Computing & WebXR Developer Β· Full-Stack Builder

B.Sc. in Computer Science & Business Administration β€” University of Florida 🐊

Qualcomm LinkedIn Email Portfolio UF Gators Location


πŸ’« About Me

I specialize in architecting production Generative AI & agentic platforms, on-device model acceleration, and immersive WebXR spatial computing experiences.

  • πŸ”­ Current Role: AI Engineer Resident at Qualcomm β€” Advancing on-device AI acceleration, edge inference optimization, neural hardware runtimes, and generative intelligence.
  • πŸ’Ό Industry Background:
    • AI Engineer at SoftwareOne: Architected enterprise GenAI solutions on AWS (Bedrock, LangChain, OpenSearch, pgvector) with tenant-isolated data governance, plus autonomous multi-tool query agents with LangGraph.
    • Machine Learning Intern at Verifone: Developed centralized multi-site fraud detection (TensorFlow, TCNN, Optuna, ClearML); achieved +20% anomaly detection accuracy and cut training time by 50% (#1 Software Engineering Team recognition).
    • Computer Vision Intern at VKIST: Engineered COVID-safe touch-free facial identification systems (PyTorch, CNN) with 87% accuracy.
  • πŸŽ“ Education: B.Sc. Computer Science, Minor in Business Administration β€” University of Florida (Dean's List). Go Gators! 🐊

πŸš€ Featured Projects

4K square spatial video extender, AI generative outpainting pipeline (LTX 2.3, Luma Ray-2, Depth Anything v2), HEVC hardware encoding, and an immersive WebXR cosmic VR player for Meta Quest 3 & Apple Vision Pro with real-time video glow (Ambilight), 6DOF spatial transport, authored Reel Packs, social feeds, and Stripe credits.

Python FastAPI WebXR Three.js React TailwindCSS FFmpeg/HEVC

Autonomous enterprise query agent built with LangGraph bridging SQL and unstructured documents. Features dynamic multi-tool routing (Vector Store, SQL Engine, Web Search, Python Code Interpreter, and Data Visualization) deployed on Azure App Service with Azure PostgreSQL (pgvector).

Python LangGraph LangChain Azure OpenAI pgvector Streamlit

Emotionally intelligent conversational assistant inspired by Her. Features dual processing modes: 100% private offline inference (Whisper STT + Ollama LLM + Bark TTS) or low-latency hybrid streaming via the OpenAI Realtime API (<0.5s response time) with dynamic emotional vocal modulation.

Python Whisper Ollama OpenAI Realtime API Bark WebRTC

Multi-agent research framework using CrewAI and LangChain. Implements intelligent switching between local DeepSeek-R1 (1.5B via Ollama) and OpenAI o1-mini / GPT-4o, with web search orchestration and automatic structured synthesis reports.

CrewAI DeepSeek-R1 LangChain Ollama Streamlit

Real-time emotive 3D digital avatar interface. Leverages Three.js and React Three Fiber with custom Web Audio FFT frequency analysis for real-time Oculus-style viseme mouth morph targets, procedural eye kinematics, and ElevenLabs realtime voice streaming.

Next.js 14 Three.js React Three Fiber Web Audio API ElevenLabs

Centralized fraud detection pipeline across 16 retail sites using Temporal Convolutional Networks (TCNN). Boosted anomaly detection accuracy by 20% and cut training duration by 50% via Optuna Bayesian optimization and ClearML monitoring.

TensorFlow TCNN Optuna ClearML Python ETL

Lightweight automation web utility for VR creators to standardize filename syntax and inject stereoscopic 180Β° / 360Β° metadata compatible with Skybox VR, Playa VR, Pigasus, and Oculus Video without re-encoding.

Python Flask VR180 Spatial Media

Interactive personal portfolio website featuring dark/light aesthetic modes, project changelogs, and an embedded AI assistant backed by Supabase pgvector semantic search.
