Full-Stack Lead Developer – Takeover Existing Property-Tech App & Finish Backend Modules (Fixed Price)

@DeveloperStation

Hi there, We’ve developed similar property management solutions with extensive backend work, including integrations with Stripe and PayPal for landlord payments. We understand the importance of delivering a stable product that meets your business goals. As a team, we can provide a dedicated backend developer, a frontend developer, and a QA expert, all at the cost of one full-time resource. This ensures you get the right expertise for each task, whether it’s backend, frontend, or testing. We’re also strong advocates of agile development, which allows us to adapt quickly to changing requirements and deliver incremental value every week. Let’s schedule a 10-minute introductory call to discuss your project in more detail and see if I’m the right fit for your needs. I’m eager to learn more about your exciting project. Best, Adil

As head of Web Crest, my 10-member expert team and I come armed with exceptional knowledge and skills that make us your ideal choice for this project. We have extensive experience in full stack development specifically working with the MERN and MEAN tech stacks. Our proficiency in Node.js and React.js will propel us through your pending 50+ backend endpoints as well as the various modules necessary to complete your NyumbanApp. Additionally, our expertise in Prisma ORM, PostgreSQL, JWT authentication, validation (Joi or similar), and Postman/Swagger documentation aligns perfectly with your project's requirements. To address your questions: (1) we have completed several backend-heavy projects. One worth mentioning is a rental management platform similar to NyumbanApp for a real estate giant; (2) in week 1, our first five steps would be codebase analysis, integration plan creation per Urjo guidelines, establish DB update requirements, prioritize api developments and set-off an uninterrupted communication process; (3) Prisma migrations hold no surprises for us- we’ve efficiently deployed them on systems and our approach emphasizes thorough research ensuring a seamless transition; (4) though our team is based in a different timezone, our flexible working hours allow substantial overlap with UK time for smooth communication.

Hello, I’m very interested in taking ownership of the NyumbanApp backend and bringing the platform to a stable, launch-ready state. With strong experience in Node.js, Express, Prisma, and PostgreSQL, I can quickly audit the current codebase, identify technical debt or missing logic, and implement the remaining modules while enforcing consistent API patterns, validation, and security practices. My approach would start with a structured audit and delivery plan, followed by implementing the pending modules (agreements, payments, tenant management, refunds, reviews), adding essential tests, and ensuring clean documentation and deployment instructions for your team. I’m comfortable working with fixed-price milestone delivery, providing regular updates, and using automation or AI-assisted tooling where useful to accelerate development while maintaining code quality. Best regards, Juan.

Taking over an incomplete backend with ~50 endpoints carries real risk around inconsistent business logic, especially in agreement and payment flows where duplicated or partial state updates can break financial integrity. I’ll start with a structured audit of the Prisma schema, service boundaries, and auth/validation layers to identify inconsistencies and hidden coupling. Then I’ll refactor into clear service modules, enforce consistent API patterns, and ensure all agreement/payment/refund flows are transaction-safe with proper state control. Prisma migrations will be handled carefully with backward-safe changes, and I’ll add Swagger docs plus targeted integration tests around critical flows to prevent regressions. I’ve delivered Node.js/Express backends for API-heavy systems (Bubbl SaaS platform with modular Express services; Aras enterprise backend focused on data integrity and APIs). I’ll take ownership of stabilizing the system and making it production-ready with clean handover for your team. Q1: Are there any known issues in current payment/refund flows or just incomplete implementation? Q2: How is authorization handled across roles (landlord/tenant/admin) today? Q3: Is there an existing staging environment with realistic seeded data for testing end-to-end flows?
