Project list

Warehouse Management System - Vietnam

This project is a system management website with functionalities for user and equipment management. It allows for adding users, managing user groups, and modifying user permissions. Additionally, it offers equipment management features such as creating and managing equipment, equipment types, and costs. Users can also view and modify warehouse design details, including the client's target budget and country.

Write API to return equipment data such as equipment name, equipment type, and equipment cost and filter client data like budget, country, and warehouse construction date. Modify web front-end to receive and include client and equipment data. Review pull-requests and provide feedback on those that do not meet coding conventions and have logic redundancy. Guide six junior members in the warehouse domain and with SQL stored procedure.

Technologies: C#, .NET framework 4.8, ASP.NET, SQL Server 2016, ADO.NET, ReactJS

Warehouse Design Software Developer - Vietnam

Developed an AutoCAD plugin tailored for warehouse designers, consolidating essential tools that leverage shared data. This software aids planners in visualizing warehouse blueprints and automatically identifies errors.

Using ACAD API to visualize AutoCAD objects and respond to commands, then process and save data into databases. Utilized geometry skills to implement features related to 3D object manipulation, such as displacement, rotation, and mirroring. Created, styled, and added additional data fields in the WPF front-end to meet engineers' requirements. Reviewed pull-requests, providing feedback on coding conventions and identifying logical redundancies.

Technologies: C#, .NET framework 4.8, WPF (MVVM), ADO.NET, SQL Server 2016, Autodesk AutoCAD

Traffic Engineering Planning Tool - Vietnam

This project involves a comprehensive traffic software system designed for traffic planners, data providers, software engineers, traffic operators, and service technicians. It integrates essential tools, leveraging a shared data platform to visualize traffic light cycles, including standard colors like red, yellow, and green, as well as special combinations such as red-yellow, red-green, and yellow-green. Furthermore, the software incorporates validation rules to help users identify and rectify errors within their traffic plans.

Port the project from C++ to .NET WPF. Draw diagrams to visualize traffic light signal colors and their durations in a time cycle. Reverse engineer the system, with limited client support, to implement intersection traffic light validation rules. Implement checkboxes to filter visualization data and modes on the diagram. Implement mouse event features to process and extract data from the traffic light diagram. Guide 5 junior members in understanding the traffic light plan and WPF framework. Review pull-requests and provide feedback on those that do not meet coding conventions or contain logic redundancies.

Technologies: C#, WPF (MVVM)

Interactive Mapping Application - Vietnam

An interactive mapping application that provides users with three viewing options: Open Street Map, Google Static Map, and a Web Map Service. Key features include the ability to mark reference points, draw lanes, and visualize traffic flow. Users can generate XML files reflecting map changes and positions, including latitude and longitude. The application maintains synchronization of map objects such as lanes and reference points during zooming, offers different layer options, and allows users to find locations by entering coordinates.

Modify model classes to store data in standardized XML formats. Synchronize import/export between Map message data and Editor data in different XML formats. Implement mouse and keyboard behaviors to move and lengthen map objects. Guide 4 juniors and new members on traffic map logic, standardized XML message formats, and the WPF framework.

Technologies: C#, WPF, .Net framework 4.8, Caliburn Micro, DevExpress, Google Map, OpenStreetMap, WMS (Web Map Service)

SX Signal Logger - Vietnam

This project is designed to read and process traffic data from SX controllers, which store raw traffic data in a database.

Processing traffic data stored in the database and writing REST API to extract them out in a standardized format. Improving front-end aesthetics and functionality to manage the data extraction process.

Technologies: ASP.NET Core, ReactJS, Entity Framework Core 2.0, SQL Server 2016

Vehicle Journey Reporting System - Vietnam

This project involves the development of a website displaying vehicle journey reports according to the QCVN31 standard. It utilizes video and GPS data from camera recorders in vehicles, which are sent to the CMSv6 platform.

Analyze the CMSv6 platform to understand requirements. Process CMSv6 API intermittently to save report data in the database. Transmit data to the Ministry of Transport server. Read CSV files transmitted via SFTP protocol to fill in data unavailable in the CMSv6 API. Install and configure various Vehicle Management Systems from different branches (CMSv6, Stonekam, etc.) on both Linux and Windows-based AWS EC2 services.

Technologies: C#, ASP.NET, MySQL, Entity Framework Core 2.0, ReactJS, AWS
