Full-Stack Developer – Ionic / React / NestJS / PostgreSQL - Rental Marketplace

@ukroficer

✔️ Hello, We can help finish your existing Ionic/React/NestJS/PostgreSQL rental marketplace rather than rebuild it. First we’d review the codebase, your screenshot/dot-point backlog, and the booking/listing flow to separate fixes, UX polish, and tech debt. - Keep Ionic React as a SPA and refine desktop/mobile flows before launch. - Convert screenshots/Figma, if available, into pixel-accurate UI changes. - Audit React state and API calls against NestJS/PostgreSQL behavior. - Test responsive layouts, core browsers, bookings, payments/maps if used. We are Webcapitan, a Ukraine web studio with 8+ years, Preferred Freelancer status, and 5★ feedback across 580+ reviews. Do you have Figma/design specs, or should we work from screenshots and the live app? Which modules are in scope: payments, maps/geolocation, messaging, reviews, or admin? Please let me know your thoughts. Looking forward, Roman

A peer-to-peer rental marketplace this close to launch usually doesn’t fail because of one big missing feature, but because of many small flow, UX, and code-quality gaps that add friction. The right way to handle this is to review the existing codebase and backlog together, then tighten functionality, remove technical debt where it affects stability, and polish the marketplace journey across mobile and desktop. I’ve worked on custom platforms where the real job was not “building pages” but improving an existing product without breaking what already works. Your stack matters here, and experience with React-based frontends, backend logic cleanup, PostgreSQL data handling, and launch-stage refinement is what makes this kind of handover efficient. Marketplace, booking-style flow, payments, and usability improvements are areas I’m comfortable stepping into. To make this easy to assess from your side, I can also share relevant examples in a clean clickable format. - Is the remaining work already grouped by priority, or is it mainly one master list with screenshots? - Are payments and map/geolocation already implemented and just need refinement, or are there still core pieces pending? - Would you want the first pass focused more on launch blockers, or on overall UX and code cleanup together?

@diektech

Hi — Elias here from Miami. It sounds like you're looking to refine a rental marketplace, which can be a complex yet rewarding endeavor. The goal here is likely to create a seamless user experience while ensuring robust backend operations. What usually matters most is the integration of various components—like user roles, payment systems, and data management. A common issue in systems like this is ensuring scalability without compromising performance. The tricky part is usually managing state effectively, as it can lead to workflow complexities if not handled well. My approach would be to structure the application with a clear separation of concerns, enhancing maintainability. Implementing a microservices architecture with NestJS for the backend and React for the frontend can provide flexibility for future expansions. I focus on utilizing PostgreSQL for reliable data handling, ensuring the system can grow as your user base increases. I've worked on similar marketplace platforms, where I ensured smooth integrations and optimized performance. A few questions to better understand the scope: Q1 – What user roles and permissions do you foresee needing? Q2 – Are there specific payment gateways or plugins you plan to use? Q3 – How do you envision handling notifications and user interactions? Happy to discuss the details and suggest the best technical approach. Looking forward to hearing from you.

@starttechno

Your existing peer-to-peer equipment rental marketplace is exactly the kind of product where careful refinement matters more than adding unnecessary features. I can work within the Ionic/React frontend, NestJS backend and PostgreSQL codebase to finish the listed functionality, reproduce and resolve smaller bugs, reduce technical debt, and polish the desktop/mobile experience before launch. I would first review the repository and screenshot-based notes, then verify the core marketplace journeys end to end: browsing, equipment details, rental/booking flow, user actions, validation, notifications and any payment or location-related integrations already present. I’ll prioritize launch blockers, make focused NestJS/API and PostgreSQL changes, refine Ionic responsive layouts, and test the main flows across mobile and desktop so fixes do not introduce regressions. I bring 10+ years of full-stack experience, with 249+ projects delivered and a 4.9-star record. Relevant work includes ClearAgent, a live multi-tenant SaaS used end to end by a customs-clearing operation, SwiftKhata, a web/desktop/mobile POS platform, and DeskLeap, a published Shopify support SaaS with a public REST API. I also pay close attention to usability and will flag places where a marketplace flow can be simplified rather than blindly following a checklist. Have the screenshot-based notes already been grouped into must-fix and polish items? Muhammad Saad

@Hammadhassan21

Howdy, When a marketplace is already well developed, the goal should be to get it launch ready without disrupting the work that’s already been done. I can work directly within your existing Ionic, React, NestJS, and PostgreSQL codebase to finish pending features, fix bugs, clean up technical debt, and improve the responsive experience across the platform. I also appreciate that you’re looking for someone who can question the existing implementation and suggest better solutions where needed. For a peer to peer rental marketplace, improving booking flows, mobile interactions, and overall usability before launch can have a big impact on the final product. I’d first review the current codebase and remaining notes with your team, then prioritise the fixes and improvements based on their actual impact instead of simply checking off tasks. I can also share relevant marketplace and full stack work in chat and discuss my experience with the stack during the Teams call.

@ranjika08

What you need now is someone who can step into an already-built rental marketplace and improve the weak points before launch, not someone who treats every note as a blind checklist. At this stage, bugs, awkward flow decisions, responsive inconsistencies, and technical debt tend to overlap, so I’d approach it by reviewing the existing app journey first and then fixing in the order that improves stability and user experience fastest. I’ve been involved in refining custom web products where launch-readiness depended on both code confidence and product judgement. For a marketplace, that usually means understanding listing flow, booking/rental logic, user actions, edge cases, and the little UX details that make the platform feel trustworthy. Working inside an existing React/backend codebase and improving it without unnecessary rewrites is a big part of that. If helpful, I can point you to similar work examples that are easy to open and review. - Roughly how many items are left in the screenshot/note list at the moment? - Is this one codebase for both web and app views through Ionic, or are there separate frontends involved? - Will you want the selected developer to handle both fixes and product suggestions, or mainly implementation after discussion with your partner?
