Featured Projects
A showcase of my best work spanning e-commerce, AI platforms, IoT systems, and more.
This project is a comprehensive parking management ecosystem designed to streamline operations and fortify security through a sophisticated blend of software and hardware integration. Built on an API-first architecture, the system ensures seamless communication between the core processing engine and various user interfaces. The desktop application, developed with Electron, delivers high-performance stability across Windows, macOS, and Linux. Complementing this, the React Native mobile suite provides a versatile experience on iOS and Android, while also being deeply optimized for handheld mini POS devices to support on-the-spot thermal bill printing. The technical core of the system leverages AI-driven models for automated License Plate Recognition (LPR) and facial matching, integrated with RTSP camera streams for real-time surveillance and IoT modules for automated barrier control.
A modern, all-in-one Point of Sale (POS) ecosystem tailored specifically for the F&B and retail sectors, offering unparalleled flexibility across diverse hardware environments. Engineered with a powerful ERP backend, the system enables real-time synchronization of inventory, sales data, and complex business workflows. The frontend, architected using React Electron and React Native, provides a unified and fluid user experience across desktop workstations, specialized dual-screen POS registers, tablets, and smartphones. Beyond standard transaction processing, the solution addresses the modern needs of digital commerce by integrating deep support for electronic invoicing (e-invoice) and leading digital payment gateways such as Momo, VNPay, and ZaloPay.
A curated selection of high-performance, visually stunning landing pages designed to meet diverse industry needs. Each project is architected with a focus on SEO optimization, Core Web Vitals, and an immersive user experience. Leveraging the power of React and Next.js, these pages implement advanced frontend techniques including Tailwind CSS for rapid, responsive styling and SCSS/CSS3 for custom, intricate layouts. Framer Motion provides fluid, state-based animations and Three.js introduces interactive 3D elements, ensuring each site stands out in the digital landscape. Projects range from live production environments for established brands to high-fidelity showcases for sectors like Logistics, Education, and Industrial construction.
Spearheaded by COVASOL, Tafas.vn is a sophisticated, high-performance e-commerce ecosystem built on Next.js. Operating in a dual-capacity role as both Lead Developer and Project Manager, I balanced hands-on technical execution with strategic leadership throughout the entire lifecycle. I personally engineered the complex business logic and high-precision system architecture required to manage thousands of intricate product variants and multi-level SKUs. A key highlight of this project is the highly complex back-office suite I architected to handle end-to-end operational management, ensuring seamless synchronization between technical backend complexity and a conversion-optimized UI/UX.
Spearheaded by COVASOL, SmartMath is an innovative, AI-driven educational ecosystem designed to provide a modern and intelligent learning environment for both teachers and students. As the Project Lead and Lead Developer, I architected a comprehensive platform that features adaptive learning paths tailored to individual proficiency, a robust online examination engine, and real-time community interaction via Socket.io. The platform's core strength lies in its integrated AI Tutor, which provides instant mathematical solutions with professional-grade LaTeX rendering, alongside detailed learning analytics and a centralized administrative suite for resource management.
A comprehensive, high-performance e-commerce and product showcase platform for SOF, utilizing a decoupled architecture with Next.js for the frontend and PHP-based APIs for the backend. A core technical challenge of this project was the seamless integration with the company's internal ERP system, enabling efficient data extraction and real-time synchronization of complex product catalogs and inventory. The entire system was engineered from the ground up, including a sophisticated product display engine, a secure online purchasing workflow, and integrated payment gateways.
A customized MiniERP/CRM ecosystem for COVASOL, built upon the Idurar open-source framework. This project involves comprehensive refactoring to align with specific enterprise needs, including a complete database migration to MySQL for enhanced scalability and data integrity. Currently leading the engineering of a brand-new frontend interface and the expansion of the backend architecture through the integration of custom modules for specialized business workflows.
A high-performance biometric recognition and attendance system designed for seamless enterprise integration. The core engine is built on a sophisticated Python stack, leveraging InsightFace for high-precision facial analysis and PyTorch for advanced anti-spoofing detection to prevent fraudulent entries via mobile screens or printed photos. Architected with a Flask-based API layer, the system provides real-time, high-FPS inference and has been successfully validated through rigorous field testing. A key technical milestone was the successful integration into a broader Smart Parking Management system, enabling simultaneous driver verification and automated attendance tracking synchronized directly with corporate ERP databases.
A centralized management platform for corporate chatbots, designed to streamline the deployment of sector-specific AI assistants. This platform empowers the company to generate and manage secure chat tokens for different business domains while ensuring that all responses strictly adhere to pre-configured knowledge bases and business rules. The system bridges the gap between raw data and conversational AI by connecting directly to the corporate ERP, fetching real-time data to provide accurate, context-aware answers. An automated documentation engine generates JSON schema and developer guides, significantly reducing integration time for frontend developers.
