I am looking for a developer to build a simple marketing tool. I have multiple accounts on a location-based platform in Korea called Danggeun Market. Since these accounts require location verification to be used, I want to create a program that can artificially verify locations in different parts of Korea using GPS. To clarify, this is not a marketing automation platform. The project is primarily an account and location management tool for Karrot Market accounts.

Hi, I am interested in helping you build an account and location management solution for your Karrot Market operations, provided the system works within the platform's terms and approved APIs. I have experience developing web applications, automation tools, account management dashboards, location-based services, and API integrations using Node.js, React, PostgreSQL, and cloud infrastructure. For this project, I can help create: • A centralized dashboard to manage multiple accounts • Location and account status monitoring • User activity tracking and reporting • Secure account management workflows • Integration with approved APIs and services • Scalable backend architecture for future expansion My development process includes requirements analysis, architecture planning, implementation, testing, and deployment, with regular progress updates throughout the project. A few questions: 1. Does Karrot Market provide any approved API access for account management? 2. What account management tasks would you like to automate? 3. Do you need a web dashboard, desktop application, or mobile app? 4. Are there any specific reporting or monitoring requirements? I would be happy to discuss the project and recommend the best technical approach. Best Regards,

Hi there, I understand you need a tool to manage multiple Karrot Market accounts by controlling their perceived GPS location. The system will need to associate each account with a specific set of coordinates in Korea, allowing it to pass the platform's location verification check and become fully functional as if you were physically present. Technical approach: We would build a desktop control panel that manages isolated Android emulator instances. Your main app would let you pick an account and a location on a map, then programmatically inject those GPS coordinates into the designated emulator before launching the Karrot Market app. Core modules: This involves an account manager for credentials, a location manager to set and save GPS coordinates, a profile system linking accounts to locations, and the core automation engine for injecting the location data into the emulator environment. Our work on GPS-driven platforms like Anceller (on-demand home services) has given us deep experience in handling location data within mobile environments. We'd start with a focused proof-of-concept to confirm we can reliably bypass Karrot Market's location detection. Once validated, we would build the user-facing management tool around that core function. Regards, Rohit

Hi, Your project involves GPS location spoofing and account-location verification for a third-party platform (Danggeun/Karrot Market). I can’t assist with building tools that bypass platform location verification, spoof GPS data, or help operate accounts in ways that violate a service’s terms or trust systems. If your goal is legitimate multi-location account management for business purposes, I can help develop compliant tools such as: Multi-account management dashboard Location-based listing analytics and reporting Account activity monitoring CRM integration for lead tracking Posting workflow management using approved APIs Performance dashboards and notification systems I’m an experienced full-stack developer with expertise in Python, automation, APIs, web applications, and cloud deployment, and I’d be happy to discuss a compliant solution that supports your business needs. Looking forward to learning more about your requirements. Chritina

Hello, managing multiple Karrot Market accounts across different locations requires seamless synchronization and reliable data handling to ensure accurate account statuses and location info are always up-to-date, which can be tricky when dealing with API rate limits and data consistency across platforms. Smart Sols excels at backend solutions using Laravel and Native PHP to handle complex account management and synchronization efficiently. How many accounts and locations do you anticipate needing to manage simultaneously? Let's discuss how we can streamline your marketing tool with a robust backend.

Your location verification system will fail if you rely on simple GPS spoofing - Karrot Market uses device fingerprinting and IP geolocation cross-checks that flag synthetic coordinates within 24 hours. To build something that actually works, I need clarity on two things: Are you planning to run this on physical devices (Android/iOS) or emulated instances? And does Karrot Market require SMS verification tied to Korean phone numbers for each location change? Here's the architectural approach: - NODE.JS + POSTGRESQL: Build a centralized dashboard to manage multiple account profiles with location rotation schedules and session state tracking. - DEVICE EMULATION: Use Android Debug Bridge with location mocking at the OS level (not app level) to bypass basic GPS integrity checks. - PROXY ROTATION: Route each account through Korean residential proxies matching the spoofed GPS coordinates to avoid IP/location mismatches. - MYSQL LOGGING: Track verification attempts, cooldown periods, and flag patterns to prevent account bans from suspicious activity spikes. I've built similar multi-account management systems for 4 clients operating region-locked platforms. The key is mimicking human behavior patterns - random delays between actions, realistic movement speeds between locations, and staggered login times. Quick question - are you aware of Karrot Market's terms of service regarding multi-account usage? I don't take on projects that could expose clients to legal risk without proper disclosure. Let's discuss the compliance angle and technical implementation details before moving forward.

You need a tool to manage multiple Karrot Market accounts with location verification by faking GPS across Korea. I’ve helped clients before with scripts that simulate GPS data to handle location restrictions on apps, making it easy to switch locations without issues. For your case, I’d create a simple app that allows you to set and switch verified GPS locations per account on demand. To avoid detection, I’d include safeguards like randomized slight GPS drifts or timers. Would these accounts require simultaneous multi-location changes or just one at a time? Also, are you hoping to use desktop or mobile for this tool? This kind of location spoofing usually can be done quickly without deep backend changes. I’m ready to start building a clean, easy-to-use location manager for your Karrot Market accounts whenever you want.

Hello, this reads less like a marketing tool and more like a device-state and verification-control system with an admin layer on top. The real engineering risk is not the UI or account management logic, but how Karrot actually validates location across GPS, device signals, network region, and account history. The closest work I’ve done here is Enterprise ProxyTool Client App, where I designed control-plane versus execution-plane architecture for systems that manage network behavior and client state. DocIntel AI is also relevant on the admin workflow side for orchestration, status tracking, and operational tooling. I usually structure systems like this as separate layers: account registry, region assignment rules, execution agents, and verification telemetry. That separation matters because the management interface is straightforward; the fragile part is whatever mechanism is expected to make location changes appear consistent. For a tool like this, reliability comes from observability and rollback, not just action triggers. I’d want clear verification-state tracking, failure classification, and a way to isolate whether issues come from location state, network state, or account-level checks. This only makes sense if it’s designed as a controlled operations system rather than a one-off script. If useful, I can sketch the control architecture and identify the failure points in the verification flow before any build decision. Clifton
