We are looking for a seasoned VB.NET Developer with strong hands-on experience working with the DevExpress control suite to work on and enhance an existing business management desktop application. The application is already developed, and we are looking for someone who can quickly understand the existing codebase, architecture, database, and DevExpress implementation, and then take ownership of ongoing development, enhancements, maintenance, and new requirements. The developer will be responsible for understanding the existing application and implementing new features, modifications, improvements, bug fixes, reports, dashboards, and other business requirements as needed. Key Responsibilities: Understand and work with the existing VB.NET desktop application and its current architecture. Work extensively with DevExpress WinForms controls and components. Understand and work with the existing SQL Server or relational database structure. Modify and enhance existing modules based on business requirements. Develop new modules and features when required. Make UI improvements and enhancements using DevExpress controls. Develop and modify reports, dashboards, charts, and printable documents using DevExpress Reporting. Work on user roles, permissions, login security, application settings, and other administrative functionality. Identify and fix bugs, performance issues, and application-related problems. Make database changes, queries, stored procedures, and other database enhancements as required. Ensure new changes integrate smoothly with the existing application without affecting existing functionality. The developer should be flexible and comfortable working with different types of requirements. Requirements may vary depending on business needs and may include new features, changes to existing functionality, UI improvements, database changes, reports, integrations, bug fixes, performance improvements, or other technical requirements. The ability to understand an existing system, analyze requirements, suggest practical solutions, and implement them efficiently is very important. The developer should be comfortable working across the application rather than being restricted to a specific module or type of task. Expected Deliverables: Enhancements and new features to the existing application. Bug fixes and performance improvements. New and modified DevExpress reports and dashboards. Database updates and required database scripts. Clean, maintainable, and well-commented VB.NET code. Updated application builds and installer packages when required. Documentation for significant changes and new functionality. Ideal Candidate: Strong experience in VB.NET / .NET desktop application development. Strong hands-on experience with DevExpress WinForms controls. Experience with DevExpress Reporting. Good knowledge of SQL Server and relational databases. Experience with Entity Framework and/or ADO.NET. Ability to understand and work with an existing codebase. Strong debugging and problem-solving skills. Ability to work independently and understand business requirements. Flexible and comfortable working on different types of requirements and changes. Experience maintaining and enhancing existing production applications is highly preferred. If you have previous experience working on VB.NET and DevExpress desktop applications, please share relevant project details, screenshots, runnable samples, or repository links when applying.

Hi, I read through the full scope. Building this as modular from day one, separate projects or layers for Inventory, Employees, Finance and Admin, will matter a lot given you want modules added and changed during development. That structure keeps later changes from breaking earlier work. I work in VB.NET and C# on WinForms desktop apps, with SQL Server and Entity Framework for the data layer. I've built role-based auth, permissions and settings modules on past desktop projects, plus installer-ready deployment (Inno Setup/MSIX). I'm comfortable adapting to DevExpress's grid, reporting and dashboard components for this build. Given the evolving scope, I'd suggest we lock the first milestone (core modules plus auth) with a clear deliverable and price, then scope each additional module separately as you finalize priorities. That protects both of us from open-ended "zero bug" acceptance with no defined test process. Which module do you want built and working first, Inventory or Finance?

Fourteen years maintaining and extending VB.NET and C# desktop business systems, ERP, payroll and inventory for a manufacturing group, is the shape of work you are describing: someone who reads an existing codebase, changes it without breaking what already runs, and keeps reports and stored procedures healthy. Straight answer on your sample request: my grids, role based logins and printable reports were built on native WinForms and SQL Server, not on the DevExpress suite itself. The layer underneath, data binding, reporting and the SQL behind it, is where I have lived for years. If a sample would help you decide, say the word and I will build a small DevExpress WinForms app, one grid and one report bound to SQL Server, and have it with you in a few days. I can commit 20 hours a week consistently, and I would rather tell you that up front than promise 40 and miss it. Happy to start on whatever part of the backlog is hurting most.

Hello, I’m an experienced Team Lead, Software Architect, and hands-on .NET Developer with strong experience in VB.NET, C#, WPF, WinForms, .NET Core/.NET, SQL Server, and business applications. I understand that you need someone who can take ownership of an existing application, quickly understand its architecture and database, and implement changes safely without affecting existing business functionality. I can help with your VB.NET + DevExpress application, including new features, DevExpress UI and reporting, dashboards, bug fixing, SQL/database changes, performance improvements, and ongoing maintenance. With both architecture and hands-on development experience, I focus on finding practical, maintainable solutions rather than unnecessarily changing an established system. I’d be happy to review the existing application and discuss the requirements. Looking forward to working with you.

Hello, Your brief is clear on the target: a polished, installer-ready DevExpress WinForms app with roles, reporting and modules like Inventory or Employees. Two points usually decide how such a project actually unfolds, so a few questions before anything else. The module list stays open ("finalized during development"). Would you rather I deliver one operational module (Inventory or Employees) fully working with authentication, roles and a DevExpress report first, then roll out the others iteratively? That keeps something usable in your hands early. Also: is the app meant for a single workstation, or a SQL Server database shared across a network? And do you already hold an active DevExpress license, or should that be planned separately? Both shape the architecture from day one. Happy to discuss your priorities whenever suits you. Best regards, Eric

You need a developer who can drop into an existing VB.NET/DevExpress codebase fast, own it, and deliver without hand-holding. That's exactly what I do. My approach: start with a structured code and database review, map the architecture, then move straight into your backlog. I work with DevExpress WinForms controls daily, including Reporting, Dashboards, and Grid Suite, alongside SQL Server stored procedures and schema changes. I can handle the full scope: new modules, bug fixes, UI improvements, role-based security, and reports. Typical ramp-up: productive within the first two days. What's the primary pain point you want tackled first?
