In this case study, we will explore how our team developed a decentralized voting system using Ethereum smart contracts and a .NET C# application. The objective was to create a transparent, tamper-proof, and secure voting system that leverages blockchain technology to enhance the democratic process. By combining the power of Ethereum smart contracts with the familiarity of .NET C# development, we were able to deliver a robust solution that met all project requirements.

In this article, we will explore how to integrate Python's Rembg library with C# to add background removal functionality to a .NET application. Rembg is an open-source library available on GitHub that utilizes deep learning models to effectively remove the background of images. Although the library is written in Python, we can still leverage it in our C# application using the Python.NET package. This will allow us to call Python functions and use Python objects directly from our C# code.

Efficient and accurate billing processes are crucial to the financial health of a business. In the case of a Singapore energy company, the finance department faced challenges in producing timely monthly billing reports for major corporate clients. With data spread across multiple servers and sub-system databases, the in-house IT department struggled to keep up with the demand for report generation. In this article, we discuss the design and implementation of a .NET-based report system that strea...

Reflection is a powerful feature in C# that allows us to inspect and interact with the metadata of types, objects, and assemblies at runtime. In this article, we will delve into the basics of Reflection in C#, demonstrate how to explore object properties dynamically, and create Microsoft SQL Server strings for database operations such as insert, update, and delete.

This article describes a secure and compliant visitor logging system for a Singapore hospital that ensures unique visitor identification while adhering to PDPA regulations. The solution uses a combination of hashed IC numbers and partial IC number verification. The implementation is built on the Microsoft .NET Framework, MS SQL, and Windows Server 2019.

In the complex world of global chemical imports, multinational corporations face the challenge of navigating diverse regulations and import limits across different countries. Furthermore, these limitations can change annually, and multi-country collaboration can lead to delays in the requirements gathering process. In this article, we discuss the implementation of a compliance check system that addresses these challenges while providing flexibility in production planning and material usage.

This technical article details the process of leveraging blockchain technology to secure complex financial forecasting parameters and reports for a Singapore company that provides financial forecasting systems to commercial real estate management companies. By utilizing the Ethereum blockchain to store hashed values of forecasting settings and completed reports, the integrity and security of the data are ensured, while maintaining confidentiality.

In light of policy changes, property developers are now expected to create their own Executive Condominium (EC) Sales and Report Systems, rather than rely on the Housing and Development Board (HDB) provided system. This shift presents several challenges, including secure data integration with the HDB system, real-time report generation, and high-performance requirements during property launch days. In this article, we discuss the design of a secure and high-performance EC Sales and Report System...
