Car Listings Alert App Build

@AwaisChaudhry

Hi there, I understand you want an end-to-end car listings alert system that ingests data from multiple sources, deduplicates and normalizes it, matches listings in real time against user filters, and sends push notifications to Android and iOS devices via FCM/APNs. I’ll build a single cross‑platform codebase and a slim, fast backend with robust test coverage, containerized deployment, and a clear API spec. My approach is to set up resilient data ingestion with rotating agents/proxies, a centralized store, a real-time matching engine based on lightweight rules, and a reliable notification pipeline with deep links. I’ll implement a clean mobile UI for sign up, saved searches, browsing, and settings, plus a shared API surface with Postman/Swagger docs. I’ll demonstrate live ingestion, matching, and push within a test device in real time to validate acceptance criteria. What is the expected data freshness tolerance for sources with intermittent availability? Which user attributes will be mandatory for sign-up and saved searches? How many concurrent listings per user should the system tolerate without performance degradation? Are there preferred proxy providers or regions to optimize scraping coverage? What is the target mobile app release timeline and any design guidelines I should follow? Do you require OAuth for sign-in or a custom auth solution? Any specific analytics or logging requirements beyond standard errors and events? Should we expose a public API for partners

Hello, This is a real-time event-driven system, not just a scraper, and I’m comfortable designing it end-to-end. I’ve built ingestion pipelines and rule-based matching engines before, including systems where fresh records trigger immediate downstream actions. I can share relevant examples in chat. Architecture Proposal Backend • Python (FastAPI) or Node.js (NestJS) • Scrapers with rotating proxies + user-agent pools • Official API ingestion where available • PostgreSQL with deduplication logic • Redis for near real-time matching • Background workers (Celery/BullMQ) Matching Engine • Event-triggered filter evaluation • Indexed user-criteria tables • False-positive-safe rule comparisons Notifications • FCM (Android) + APNs (iOS) • Deep-link support Mobile App • React Native (single codebase) • Auth, saved searches, listing browser, notification controls All containerized via Docker with full README + Postman/Swagger documentation. Estimated timeline: 8–10 weeks depending on marketplace complexity. Happy to walk through scaling and anti-blocking strategies before kickoff. Best regards, Athar

@corpmember29

Hello, {{{ I HAVE CREATED SIMILAR APPS BEFORE AND I CAN SHOW YOU }}}} I have 10+ years of experience building real-time scraping systems, event-driven backends, and cross-platform mobile apps. Your car listings alert concept is clear and technically achievable with a clean, scalable architecture. I will build a backend with rotating proxy-based scrapers + official API ingestion where available, normalize and deduplicate listings into PostgreSQL, and trigger a real-time matching engine that evaluates user filters (make, model, year, mileage, price, location, keywords). Notifications will be delivered via FCM (Android) and APNs (iOS) with deep linking into the app. The mobile app (React Native preferred) will include secure auth, saved searches, live match feed, and notification controls. Backend will include automated tests, Dockerized deployment, and complete API documentation (Swagger/Postman). The system will be optimized to ingest, match, and push within 60 seconds. I WILL PROVIDE 2 YEAR FREE ONGOING SUPPORT AND COMPLETE SOURCE CODE. WE WILL WORK WITH AGILE METHODOLOGY AND WILL GIVE YOU ASSISTANCE FROM ZERO TO PUBLISHING ON STORES. I eagerly await your positive response. Thanks.

The system will be optimized to ingest, match, and notify within seconds while ensuring accuracy and scalability. **Questions:** 1. Which specific car marketplaces should be prioritized first? 2. Do you already have developer accounts for Apple Push and Firebase? 3. Will this system support thousands of users immediately or start small and scale? Thanks Divu..

@efanntyo

Hi there, I’m Efanntyo, a seasoned full-stack developer and AI specialist with hands-on experience delivering end-to-end systems like your Car Listings Alert App. I’ve built scalable data pipelines that ingest from multiple sources (web scrapers with rotating user-agents and proxies, API consumers, and data normalisation), deduplicate listings, and funnel data into a robust PostgreSQL store. I’ll design a lightweight yet fast matching engine that evaluates new listings in real time against each user’s saved filters (make, model, year, mileage, price, location, keywords) with minimal latency to guarantee that matches can trigger notifications within seconds of publication. For notifications, I’ll implement a unified push solution using FCM for Android and APNs for iOS, delivering deep links that open the exact listing inside the app. The mobile client will be a single cross‑platform codebase (React Native, with optional Flutter consideration) to accelerate delivery while preserving a polished UX for sign up, saved searches, browsing current matches (with images, price and source), and notification controls. Deliverables will include: - Backend source (scrapers, API, matching logic, notification service) with automated tests. - Containerised deployment scripts (Docker Compose or Helm) and a clear README. - Mobile app source code with a short build guide. - API documentation via Postman collection or Swagger. - A live demo showing ingestion, matching, and a push to a test dev

@arzoof1

Hello, this is exactly the kind of real-time system I build — high-speed ingestion, smart matching, and instant push delivery with production reliability. I can architect a scalable pipeline using rotating proxy-based scrapers + official APIs feeding into PostgreSQL, a lightweight rule engine that evaluates new listings within seconds, and a containerized Node.js backend with automated tests and Swagger docs. For the app, I recommend React Native for a single clean codebase, integrated with FCM and APNs for true real-time deep-linked notifications. I focus heavily on de-duplication accuracy, <60-second ingestion latency, and zero false positives in controlled test sets. I can deliver the full stack with Docker deployment scripts and a live demo proving end-to-end flow. Best Regards, Arzoo Farooq
