Looking for a Full-Stack Flutter & Node.js Developer for "NearByt" (Local Marketplace MVP)

@mrresearcher99

Hello, I’m a full-stack and mobile developer with 10 years of experience building scalable marketplace, chat, CRM, and mobile applications. I can build NearByt using Flutter for Android/iOS with Node.js, PostgreSQL, REST APIs, and real-time communication. I would structure the MVP around secure Firebase OTP authentication, location-based discovery, PostGIS radius queries, optimized listing creation, image uploads, listing-based chat, direct communication, offers, and moderation tools. The backend will use clean API architecture with scalable database design, while Flutter will provide a responsive and smooth experience across both platforms. I can also provide relevant marketplace and communication app examples during our discussion. Let’s discuss the MVP scope and development milestones. Best regards

Hi, there I can build the NearByt MVP with Flutter on Android/iOS and a structured Node.js backend using NestJS, PostgreSQL/PostGIS, and Socket.io. I’d keep the architecture focused on the core marketplace flow: Firebase phone authentication, location-based discovery with radius filtering, fast listing creation with image uploads, real-time listing-based chat, offers, calling triggers, and a practical moderation dashboard. For proximity search, PostGIS can handle efficient distance queries while keeping the API ready to scale as listings and users grow. I’ll also keep the Flutter UI responsive and consistent across both platforms, with clear API separation for future features. Looking forward to work with you. Thanks Fernando

In addition to my technical acumen, I value the goal of NearByt - enabling free listings, zero commission transactions, and frictionless communication. With this platform having a gentle approach of monetization through local business profiles and targeted advertising, I believe the user experience should be smooth and streamlined. And that's precisely what I consistently aim to deliver: a robust system that solves real problems while staying scalable as you grow. My standard availability is X hours per week and my estimate for a project of this scope is around X weeks. However, I prioritize maintaining open communication throughout the project’s lifecycle, tuning timelines and budgets accordingly as we go. Above all else, I am invested in nurturing long-term client relationships as it fosters trust and paves way for superior product development. Let’s transform your idea into a reliable and scalable reality together!

Hello. Thank you very much for your chance. I have read your project description carefully. I'm a Web, AI & Android Custom | Python, WordPress, Java with over 8 years of experience working with Flutter, Node.js, PostgreSQL. I understand you need a NearByt MVP: Flutter app for iOS and Android, a NestJS API with PostGIS proximity search, OTP auth, a geolocation feed, listings, real-time chat and basic admin moderation. The real challenge is proximity search at scale. A common issue: distance filtering is done in the app after loading all listings, so the feed slows and shows the wrong radius. I would query distance in PostGIS with a spatial index. I can build it perfectly : First, the schema, PostGIS setup and auth. Then, the listing flow, feed and chat. Finally, admin moderation and store-ready builds. Q1 - Should the first release cover both platforms, or Android first to ship faster? Q2 - I'd use PostGIS with a spatial index for radius search, not app-side filtering. Agree on that? Q3 - Indian phone numbers need an SMS gateway like MSG91 for OTP. Do you have one? Let's connect over a chat so we can discuss this in more detail. Best regards , Muheebwa

@LukeKenyon

Proximity search that feels instant at 1.4 km but crawls at 10 km almost always means the distance filter is running in application code instead of a PostGIS spatial index, and that choice has to be locked in before the first API route gets written. Should listings expire automatically after a set number of days or stay live until the user closes them?

Hi, I saw your project "Looking for a Full-Stack Flutter & Node.js Developer for "NearByt" (Local Market". I run a multi-pair crypto trading bot in paper mode, with its backtesting validated out of sample, plus another one wired to MetaTrader 5 across 24 forex, index and metals instruments. For yours: the bot runs your strategy with each position sized off the loss at stop, wired to your exchange or MetaTrader, and pings you on Telegram. Before you commit a cent I show you the backtest on real data, fees and spread included. Estimated time: 5 weeks. Price: USD 3420 to 5130, depending on the final scope we agree on. Something you should know up front: I measured one of my own bots, found it had no real edge, and said so instead of selling it anyway. I will do the same with you: if the numbers do not hold up, I tell you. Want me to run your strategy through it and show you how it would have done before you decide?

@crislucero22

Hi! NearByt's core is proximity search on Postgres, which is exactly what I built for Nook, my cafe-finder app live on the App Store (search "nook - Cafe Finder"; screenshots in my portfolio). What carries over: - Flutter app for iOS and Android, shipped by me (led a 3-person team, wrote most of the code) - PostGIS radius queries (ST_DWithin / ST_Distance) behind a "near you" map with km distances, same as your 1/5/10 - Admin console for reviewing listings, plus report and block-user moderation - Realtime (Pusher) in productilatform with an Expo app that Imaintain To be upfront: my recent backends are Supabase, Laravel and CodeIgniter, not NestJS, though I work in Node/TypeScript daily. hat; my realtime work is Pusher, same pattern. This budget covers a solid first milestone, not the full MVP: Milestone 1: Firebase phone OTPlocation feed with distancefilters on NestJS + PostGIS, delivered as a working Android/iOS build. Listings, chat/calls and admin , quoted after you've seenMilestone 1. Availability: 15-20 hours/week. Full MVP: roughly 6-8 weeks.

@aakaashberi

Hi, I can begin NearByt with a clear MVP foundation: review the user journeys, set up the core data model, and deliver a working first flow for account creation, a location-aware listing and basic moderation-ready admin access. This lets us validate the marketplace experience before expanding chat, notifications and launch infrastructure. INR 10,000 covers the discovery and first vertical slice in 4 days. I will provide a phased backlog after reviewing the preferred Flutter, Node and hosting setup. Please share wireframes, the intended geographic launch area and the must-have listing fields.
