Senior Ionic / React / NestJS Developer Needed – Finalise Marketplace & Polish UX

@rajat07me

Hello, Heavy Hires - this is the kind of project I like working on most: stepping into an existing product, understanding the codebase properly, and improving both the functionality and the feel before launch. I have solid experience with React-based products, backend cleanup, refactoring, and polishing user flows so the platform feels more premium and intuitive. Your brief makes it clear you want thoughtful input, not just ticket completion, and that suits my working style well. I’d be happy to review the current state, identify quick wins, and help you finish this in a clean and scalable way.

@Microlent

Hi, I have gone through your website and web app project to finalise the Ionic / React / NestJS marketplace and polish its UX. It looks straightforward at first, but marketplace workflows, API integration, PostgreSQL data handling, and cross-platform UI consistency can cause issues later. I can review the existing codebase and outline a practical approach to complete and refine it. I have over 10 years of experience in JavaScript, React, NestJS, Ionic, PostgreSQL, full-stack development, SaaS, and UX, and I'm excited to be part of your project. Let's discuss your marketplace, its remaining functionality, and the UX improvements needed in the chat so I can recommend the most practical and cost-effective solution. ~ Rajesh

Hi — Elias here from Miami. Heavy Hires. I see you're looking to finalize a marketplace and enhance the UX. This is crucial for user engagement and can significantly impact your business success. The real challenge often lies in ensuring scalability and maintainability as you integrate various user roles and workflows. A common issue in systems like this is managing the complexity of permissions and interactions, which can lead to bottlenecks if not handled properly. My approach would be to establish a modular architecture that allows for easy updates and future expansion while ensuring a smooth user experience. I focus on stability and maintainability, prioritizing clean code and efficient state management to handle user interactions seamlessly. I have worked on similar projects that required intricate user role management and API integrations, providing insight into potential pitfalls and how to navigate them effectively. A few questions to better understand the scope: Q1 – What specific user roles do you envision, and how will they interact with the platform? Q2 – Are there any existing integrations we need to consider for the marketplace? Q3 – What are your scaling expectations in the next 6-12 months? Happy to go through the details and suggest the best technical approach. Looking forward to hearing from you.

Hello, Heavy Hires — we understand you need a senior full-stack partner to step into an existing Ionic/React/NestJS/PostgreSQL marketplace, finish remaining functionality, reduce technical debt, and improve the UX before launch. A2 Design has been building and refining marketplace and booking platforms since 2006, with strong React-based product experience and a focus on maintainable architecture, clean user flows, and launch-ready polish. Relevant examples include MadPaws, an on-demand booking marketplace with search, filtering, escrow payments, and profile flows: madpaws.com.au. We also built Get Blys, a service booking platform with scheduling and secure payments: getblys.com.au. Your project sounds like the right stage for us: not just closing tickets, but reviewing flows, identifying friction, improving consistency, and making the product feel more premium while working collaboratively with your team. We’d be happy to review the current codebase, clarify priorities, and suggest a practical roadmap for final completion and launch readiness. Let’s connect and discuss next steps.

@softsolution2000

Heavy Hires Jumping into someone else's marketplace codebase and untangling the technical debt before launch is a very different job than building from zero, and it sounds like that's exactly the stage you're at with Ionic/React on the front end and NestJS/PostgreSQL underneath. Before I say much more, I'd rather do a small paid test task first, something like fixing one real bug or polishing one flow you flag, so you can see how I read your code and handle feedback before committing to anything bigger. That matters more than anything I can say in a proposal. My background's mostly React/Node across web and mobile projects for the last several years, running a small team, so reading an existing codebase and being picky about UX flow is normal territory for us. Happy to start with that small task this week if useful.

@ykarora26

"Heavy Hires" I'm a seasoned full-stack developer with hands-on experience in Ionic, React, NestJS, and PostgreSQL. I understand your need for someone to seamlessly integrate into your existing codebase, finalize features, address technical debt, and enhance the user experience. My previous work on similar SaaS products equips me to deliver the quality and attention to detail you value. Could you share more insights on the specific features that require immediate attention to align with your vision for the platform? Regards, Yogesh Kumar

@seefattechnologi

Heavy Hires Your platform is already built. The priority now is shipping a production ready marketplace by completing features, reducing technical debt, and refining UX without disrupting the existing architecture. My Approach: • Complete pending features within your Ionic, React, NestJS, and PostgreSQL stack while maintaining clean, scalable architecture. • Refactor technical debt, optimize performance, and improve maintainability with safe, review friendly changes. • Enhance UX by simplifying user flows, polishing interfaces, and identifying usability improvements beyond the documented requirements. I have experience working on SaaS platforms, booking systems, marketplace applications, payment integrations, and production codebases where stability and product quality were the primary focus. Please ping me to get started and deliver outstanding results. Thanks!!!

@managersingh

Heavy Hires Hi, I’m a full-stack developer with strong experience in Ionic, React, NestJS, and PostgreSQL, and I’ve shipped production marketplace and booking platforms where clean architecture, scalable code, and polished UX were critical. I’ve jumped into existing codebases to finish feature sets, refactor technical debt, and elevate UI/UX flows often spotting confusing layouts, redundant steps, and premium-feel improvements before they’re flagged. I communicate clearly, collaborate closely, and prioritise getting things right over rushing. I’d love to help you launch Heavy Hires with a platform that feels robust, intuitive, and ready to scale. Best regards, Singh

@starttechno

Heavy Hires — your platform is already substantially built, so the priority is finishing the documented marketplace features, reducing technical debt, and giving the rental journey a polished, launch-ready feel rather than rebuilding from scratch. I have 10+ years of full-stack experience, 249+ delivered projects and a 4.9 rating. My relevant work includes production SaaS, marketplace-style workflows, booking systems, payment integrations and mobile-first applications. I’m experienced with Ionic and React on the frontend, NestJS APIs, PostgreSQL data modelling, REST integrations and performance improvements. I would begin by mapping the existing codebase and reviewing the remaining feature list, then trace the key flows: equipment discovery, listing details, availability, booking, account actions and any payment or location functionality. I’ll complete missing functionality, remove redundant code, standardise patterns and address slow queries or unnecessary frontend requests. Alongside implementation, I’ll review the supplied screenshots and recordings for confusing states, inconsistent spacing, unclear actions and mobile usability issues, while also suggesting practical UX improvements that make Heavy Hires feel more premium. Is the documented feature list and onboarding material already ready for review when development begins? Muhammad Saad
