Mendix App Development and Integration

@AwaisChaudhry

Hello, I will build a robust Mendix app from scratch, optimize existing features for performance, and integrate it with external systems for seamless data flow. My approach is to define a solid data model and UI in Mendix Studio Pro, implement reliable REST/SOAP connectors with proper error handling, and apply performance best practices such as lazy loading, asynchronous tasks, and efficient microflows, followed by automated testing and CI/CD. Examples of similar work include a Mendix app for a logistics partner integrating ERP and shipping systems and a healthcare portal connecting EHR data and payment services. Timeline: 7-12 days depending on scope; MVP in 12 days with two weeks of post-go-live support. Bid: 22 USD; duration: 12 days. Which external systems need integration and data formats? Do you have an existing Mendix environment and any regulatory, security, or compliance requirements we must follow? What are the performance targets (response time, throughput) and data volumes? What is the preferred deployment approach (CI/CD, staging, production) and hosting? Are there existing authentication/security standards (OAuth2, SAML, encryption) we must conform to? Best regards,

✅ Mendix ✅ System Integration ✅ Stripe ✅ ISO 20022 ✅ Membership Platform Hi, Thanks for sharing your project! I’ve reviewed the requirements carefully and can help you rebuild your legacy Magic XPA + Oracle membership system into a modern Mendix web application with clean architecture, strong integrations, and long-term scalability. I have solid experience working with low-code platforms like Mendix, complex system integrations, payment systems, and migrating legacy business logic into modern, maintainable web apps. This project fits perfectly because it combines migration, performance improvement, and multiple financial integrations. Here’s how I would approach it in Mendix: • Recreate the membership, subscription, and donation workflows as domain models and microflows • Migrate data from Oracle into Mendix with proper mapping and validation • Integrate Resend for transactional emails and notifications • Implement Stripe, ISO 20022, BGMax Autogiro, and SWISH payment flows securely • Build modular services so future integrations can be added easily • Optimize performance using Mendix best practices for large datasets and user roles I can start immediately and would be happy to review your current Magic XPA structure to plan the Mendix domain model and migration strategy. Thanks, Purnima

Hi I can build your new Mendix application from the ground up while also modernizing your legacy Magic XPA system and integrating it with the external platforms you rely on. A key technical challenge is migrating Oracle-backed logic into a scalable Mendix web architecture, and I can model data, microflows, and domain logic to ensure performance, stability, and clean modernization. I’ll integrate Resend for email delivery, Stripe for payments, ISO 20022 workflows, and Swedish systems like BGMax Autogiro and SWISH to support memberships, subscriptions, and donations. Your existing features can be optimized to reduce latency and improve maintainability across the full membership lifecycle. I have experience building Mendix apps that connect to heterogeneous systems, ensuring smooth, secure communication through APIs and middleware. The result will be a robust, future-ready platform that supports your national associations with clear structure and reliable integrations. Thanks, Hercules

Hello There!!! ⚜⭐⭐⭐⭐⚜(( Project Goal: Migrate a legacy Magic XPA membership system into a scalable Mendix 11 SaaS application ))⚜⭐⭐⭐⭐⚜ Migrating a long running Oracle based system into a modern web application while preserving data integrity, payments, and member workflows is a serious undertaking. You are looking for a Mendix 11 consultant who can rebuild the application cleanly, integrate multiple payment providers, and prove hands-on platform skill before moving forward. I have delivered Mendix applications on existing enterprise schemas, including Oracle data sources, CSV imports into core entities, and SaaS style multi organisation setups. I focus on structuring domains for memberships, subscriptions, and donations so performance and future growth are not compromised. Three key features I would prioritize: * Oracle or CSV data import into Person and related membership entities * Secure integrations for Resend, Stripe, ISO 20022, Swish, and BGMax Autogiro * SaaS ready architecture with role based access for admins and external users If this approach matches your expectations, I would be happy to discuss the proof task and a realistic migration timeline.
