Hieu Nguyen Cong

I've built full-stack and AI products for Lumination, including voice-conversation analysis, meeting bots, transcription, speech separation, and recognition systems for partners such as VPBank, HoaSenUniversity, Vikki, and BKAV.

I work independently across frontend, backend, database design, deployment, server management, API integration, and data security. My work includes scalable real-time data systems and AI capabilities such as RAG multi-agent systems, recommendations, and feature detection.

As a freelance Full-stack Developer and AI Engineer, I've contributed to products including Bonix, IELTS Test, In Anh Ha Thu, and Ecoka, building chatboxes, real-time notifications, Google Maps integrations, smart e-commerce systems, and system administration workflows.

Earlier at BrightBrain, I designed web interfaces for Superdong ferry ticketing and restaurant ordering management, covering booking, menus, table management, and payment tracking. I'm also a Top 3 FPT Autonomous Car 2024 participant and Top 16 at FPTU Can Tho Olympic AI 2026.
