@vano101

Hello. I have solid experience with VB.NET/WinForms and database-driven applications and can deliver a maintainable foundation rather than just a working prototype. I have successfully completed hundreds of .NET projects on freelancer.com. I can build this ERP foundation in VB.NET with DevExpress WinForms and PostgreSQL, with a clean structure designed for easy expansion. I will implement: • Secure login with Administrator, Manager, and Employee roles • Role-based permissions and role-sensitive DevExpress Ribbon menu • Reporting, Settings, Preferences, and User Management sections • A complete Customers/Products CRUD module with DevExpress Grid, search, paging, validation, and add/edit/delete dialogs • PostgreSQL schema, seed data, and reliable CRUD persistence • Secure password handling and parameterized database queries • Well-organized, commented VB.NET code that can serve as a template for future modules You will receive the complete Visual Studio solution, SQL scripts, and a concise setup guide. I will ensure the project compiles cleanly, connects to PostgreSQL, enforces permissions correctly, and meets the stated acceptance criteria.

Role-based menus alone won’t secure your ERP; CRUD actions need the same permission checks. I’d build around one authorization layer shared by DevExpress Ribbon items and every add/edit/delete command, so hidden controls aren’t the only protection. Login would validate password hashes, establish the active user/role context, and open the RibbonControl menu. The sample form would use GridControl with server-side search, PostgreSQL LIMIT/OFFSET paging, dialogs, validation, and rights-aware persistence. You’ll receive the commented VB.Net solution, schema and seed scripts, plus a concise setup and extension guide. Before coding, should granular permissions be fixed by role, or configurable per user and module?

Hi, I can build this ERP foundation with a clean layered architecture using VB.Net, DevExpress WinForms, and PostgreSQL, with role based security designed so additional modules can be added without restructuring the core application. My Approach: Build secure authentication with Administrator, Manager, and Employee roles plus granular permission checks. Create the DevExpress ribbon menu with dynamic role based visibility for Reporting, Settings, and User Management. Implement a reusable Customers or Products CRUD module with grid, search, paging, validation, add/edit/delete operations, and PostgreSQL persistence. I will provide the Visual Studio solution, commented VB.Net code, database schema and seed scripts, configuration, and setup documentation. The architecture will be structured as a reusable foundation for future ERP modules. Please share your preferred DevExpress version and PostgreSQL version so I can align the solution correctly. Please ping to get started and get outstanding results. Thanks!!!

@ahmadayaz

I will develop a VB.Net solution with DevExpress WinForms controls and PostgreSQL to create a secure login screen, dynamic main menu, and CRUD form as a template for future modules. The solution will feature robust authentication, role-based permissions, and a main menu tailored to each user's role. The CRUD form will support operations like add/edit/delete, validation, paging, and search for a sample entity. Deliverables will include a commented Visual Studio solution, SQL scripts, and a setup guide. The solution will seamlessly connect to PostgreSQL, support role-based access, and enable complete CRUD operations. Ongoing support and enhancements will be provided for a long-term partnership.

Please let me know if you have any questions or need more details. Thanks!

@sufyanasmat38

Hi, this is a clean, well-scoped ERP foundation build — a solid CRUD template with role-based access is exactly the kind of extensible base project I like getting right from the start. Approach: Login screen with role-based authentication (Administrator/Manager/Employee) validated against PostgreSQL, with permissions enforced at the data-access layer, not just hidden UI elements — so restrictions hold even if someone tries to bypass the menu. DevExpress ribbon-style main menu with items conditionally rendered based on the signed-in role's permission set, structured so adding new modules later just means registering a new menu item + permission flag, not reworking the menu logic. Customers (or Products) CRUD form as the reusable template: DevExpress grid with paging/search, add/edit/delete dialogs with validation, all persisting to PostgreSQL and respecting the active user's rights — built as a clean pattern you can copy for future modules, not a one-off. Deliverables: Visual Studio solution with commented code, SQL scripts (schema + seed data for roles/users/sample table), and a setup guide to compile, run, and extend. Happy to lock any requirement details before starting, as you suggested.

@maxscender

I can help you build a solid foundation that you can build on for years, not just a prototype. The core challenge isn't just code; it's ensuring your three user roles, menu visibility, and data access are strictly enforced at every layer. I'll structure the solution with a clean separation between the UI and data-access layers, making future modules straightforward to add. The CRUD form will use PostgreSQL stored procedures for data integrity, and I'll build a reusable pattern for validation so every future form follows the same rules. The deliverable will be a complete Visual Studio solution that compiles cleanly and runs against a fresh PostgreSQL instance. The setup guide will focus on the few configuration points only, so you can get it running fast without sifting through unnecessary details.

@Rapha

Hello, my name is Rafael. I’ve worked on desktop business applications with role-based access, database-backed CRUD workflows and modular architectures designed to grow into larger ERP-style systems. For this foundation, I’d keep the structure simple and reusable: VB.Net with DevExpress WinForms for the UI, PostgreSQL for persistence, and a clear service/data-access layer so future modules can follow the same pattern without duplicating logic. I’d implement secure login for Administrator, Manager and Employee roles, then enforce permissions both in the UI and in the underlying operations. The DevExpress ribbon menu would expose Reporting, Settings & Preferences and User Management only where the active role allows it. For the sample module, I’d use Customers or Products and build a complete CRUD flow with DevExpress GridControl, add/edit/delete dialogs, validation, search and paging, all persisted to PostgreSQL and checked against the signed-in user’s rights. You’ll receive the Visual Studio solution, commented VB.Net code, SQL schema/seed scripts and a concise setup guide showing how to compile, run and extend the pattern for new modules. Contact me to discuss the preferred sample entity and permission matrix so I can define the first reusable ERP module cleanly from the start.

@denisSolution

Hi, This sounds like a clean starting point for a modular ERP foundation. The main challenge is making sure the role-based logic is consistent across the login, menu, and CRUD layer, so the code stays easy to extend later. I’ve built similar internal tools in VB.Net with DevExpress and PostgreSQL, where the tricky part was keeping the permission checks in sync between forms. The setup guide and commented code make it easier to hand off, which matches what you’re asking for. I’d start with a lightweight authentication layer tied to a roles table, then build the ribbon menu as a DevExpress bar manager that toggles items based on the user’s role. The CRUD form would use a DevExpress grid with built-in paging and search, all wired to a PostgreSQL backend through Entity Framework or raw ADO where it makes sense. The biggest unknown is how the roles map to specific permissions—we can lock that down once we confirm the exact rules. Thanks, Denis.

@mayr81

You’re building a lightweight VB.Net ERP foundation with DevExpress WinForms + PostgreSQL, so the deliverable will be a clean Visual Studio solution structured for growth: secure role-based authentication (Administrator/Manager/Employee), a DevExpress ribbon main menu whose items appear only for the active role, and a single fully functional CRUD module (e.g., Customers) demonstrating DevExpress grid, add/edit/delete dialogs, validation, paging, and search. I’ll include: - Commented VB.Net code with a modular architecture (Auth/Permissions, Menu Builder, Repository/CRUD) - SQL scripts: schema + seed data for roles/users + the sample entity - A brief compile/run/extend guide (including PostgreSQL connection setup) Acceptance target: compiles cleanly, connects to PostgreSQL out of the box, logs users in with enforced granular permissions, renders the role-sensitive menu, and persists full CRUD to the database with rights enforced per operation.

Your role-based permission layer will fail under load if you're checking access rights on every grid operation instead of caching them at login. That creates unnecessary database round-trips and slows down the UI when users filter or page through records. Quick questions - are you planning to store audit logs for every CRUD action, and do you need the permission model to support custom roles beyond the three defaults? Here is the architectural approach: - VB.NET + DEVEXPRESS: Build a reusable base form class that handles permission checks, grid binding, and validation so every future module inherits consistent behavior without duplicating code. - POSTGRESQL SCHEMA: Design a normalized role-permission table structure with foreign keys to enforce referential integrity and support role expansion without schema changes. - AUTHENTICATION LAYER: Implement token-based session management that caches user permissions in memory at login and expires after inactivity to prevent stale access rights. I've built similar ERP foundations for 2 manufacturing clients where the prototype scaled to 40+ modules without refactoring the core architecture. Let's schedule a 15-minute call to confirm your permission granularity before I start the build.
