Taxi App Developer - Bug Fixes & Publishing

@Tafsol

Hi, Could you please share the existing live platform/app links, App Store or Play Store links if currently published, and the current bug list so I can understand the present state of the system? I would first review the existing codebase, current bug list and complete booking flow to understand how the mobile apps, backend, dispatcher and location services are connected. From there, I would reproduce each issue, identify the actual root cause, fix it without disturbing working modules, and test the full connected flow. For location search, I would improve ranking using GPS proximity, service area, exact search intent, place type, user history and preferred locations, while keeping API usage efficient through caching, debouncing and intelligent search-radius expansion. -/ What technologies are the customer app, driver app, backend and dispatcher currently built with? -/ Which MapTiler/MapLibre services are already being used for autocomplete, geocoding, routing and reverse geocoding? -/ Is the Chesterfield local-search issue happening only in autocomplete, or also when selecting pickup/drop-off locations from the map? Freelancer didn't allow me to write more than 1500 words, Let's jump over an on-site chat or on-site freelancer call to walk through everything and then proceed from there. Best regards, Tafsol(MKA) Budget and Duration are TBD

Hi, I understand you need an experienced developer to fix the current taxi platform without rebuilding working parts. I would first review the code, bug list, API flow, GPS updates, booking process, and MapTiler/MapLibre location search. I would improve local result ranking so nearby Chesterfield Tesco appears first while still finding Heathrow Terminal 5, using sensible radius expansion, debounce, caching, and clear fallback handling. Each fix would be tested across customer, driver, dispatcher, and admin flows, with regression checks, evidence, meaningful Git branches, and documented commits. I can work with your two developers and help prepare the iPhone and Android builds for App Store and Play Store release. My focus is Mobile App Development rather than WordPress, and I will keep all code and credentials confidential. Could you please share the current technology stack, repository access process, bug list, and which MapTiler/MapLibre search or publishing issue is the highest priority? Thank you for considering my proposal.

Hi there, could you please share the current tech stack of the customer/driver apps and confirm whether MapTiler/MapLibre and the existing location search are already integrated? I can review your existing taxi platform, work alongside your 2 current developers and fix issues across the mobile apps, backend/API, GPS, live tracking, booking/dispatch flow and location services without rebuilding the working system. I can also review the MapTiler/MapLibre search flow to improve local relevance, autocomplete, reverse geocoding, pickup/drop-off coordinates, route and distance calculations, while keeping API usage and third-party costs under control. I’ll follow a proper reproduce → root cause → fix → regression test process and can assist with Android/iOS production builds and store publishing. -/ Are the customer and driver apps built with Flutter, React Native, or native Android/iOS? -/ Is MapTiler currently the only geocoding/search provider, or are you using another service for autocomplete and reverse geocoding? -/ Could you share the existing bug list and a relevant codebase/demo so we can identify the highest-priority issues first? I’ll work through the existing bug list systematically, test the complete customer-to-driver booking flow, provide evidence for completed fixes and keep all changes properly managed through Git so they can be reviewed by your existing team.

@HamparProd

Hello, I have 5+ years of mobile and full-stack experience. My portfolio includes the Flywheel taxi apps for iOS and Android. I’ve published apps on both stores and can work with your developers through branches, pull requests, regression tests, and evidence for each completed fix. My taxi-app work gives me relevant location-flow experience, but I haven’t used MapTiler or MapLibre on a project I can cite, and I can’t claim a separate autocomplete implementation. I’d review your existing setup first. For “Tesco,” I’d rank results using GPS, pickup point, service area, proximity, and text/category match; an explicit query like “Heathrow Terminal 5” should preserve the distant exact match. I’d reduce unnecessary requests with minimum query length, debounce, appropriate session handling, and caching where the provider’s terms allow. Given the posted budget, I suggest starting with a limited milestone to review the bug list, reproduce the highest-priority location issue, and fix one clearly scoped bug with a tested build and documented evidence. Broader fixes and store submissions would need follow-on scope. I can start after award and access to the repository, bug list, and test builds.

@bcosley

Hi, I understand this taxi platform needs stability across mobile apps and backend, with MapTiler/MapLibre and careful app publishing. I’ve worked on similar rideshare and dispatch systems where GPS, location search, and map accuracy drive user trust and operator efficiency. Execution approach: I’d start by reproducing the top bugs, isolating root causes in the current flow, and validating fixes against end-to-end booking, tracking, and dispatch. I’ll add focused regression tests and ensure map pins, routing, and distance calculations align with bookings before a production push. One technical risk / key challenge: keeping local search relevance high while controlling API costs and latency. Two clarification questions: 1) What is the most critical user journey to stabilize first, and what’s the current failing pathway? 2) What are the publishing milestones and any blockers for App Store/Play submission? If we're aligned, I can outline the implementation phases before kickoff. Best regards, Brandon

@melikatfz

Hey, tackling that localized search ranking for things like Chesterfield Tesco while keeping distant spots like Heathrow accessible is a great geospatial query problem, especially with MapLibre and MapTiler. I’ve built location-aware autocomplete pipelines before using coordinate bounding boxes combined with text matching to keep API costs low and local results first. Handling store submissions and live GPS tracking alongside an existing team is right in my wheelhouse. How are you currently handling the bounding box radius expansion in the search logic?

@wontonesaju

Hi, I can help review your existing taxi platform, debug issues, improve GPS/location handling, and stabilize the customer, driver and dispatcher workflows without rebuilding working features. I’m experienced with React Native, JavaScript, REST APIs and Git-based development. I can also work alongside your existing developers, test fixes thoroughly, and assist with production builds and app publishing. 1. Is the mobile app built with React Native or Flutter? 2. Are MapTiler and MapLibre already integrated into the current app? 3. Can you share the existing bug list and repository structure? Thanks Saju

@Eliteinno

Hey, that intelligent search requirement is a great detail — weighting local results like Chesterfield Tesco while still allowing distant lookups like Heathrow. I've tackled that exact geo-scoring setup using MapLibre and local bounding boxes to keep geocoding costs low. Working alongside your current team to knock out that bug list and get builds pushed through App Store Connect sounds like a solid fit. How are you currently handling the debouncing on your autocomplete inputs?

@denisSolution

Hi, I'm Denis, a full-stack developer with 8 years of mobile and backend experience. I've worked on location-based platforms involving GPS tracking, real-time dispatch, and map integrations—exactly what you're building. I've extensively used MapTiler and MapLibre on similar projects and understand your local relevance challenge. The solution combines proximity scoring based on GPS location with text match strength, intelligently expanding search radius when needed. For specific searches like "Heathrow Terminal 5," exact address matching bypasses proximity filters. I'll implement debounced API calls, result caching, and duplicate filtering to minimize costs. I've debugged live tracking systems, fixed GPS marker jumping, handled location permissions, and resolved coordinate-to-address mismatches in production. I've also personally published apps to both App Store and Google Play, managing certificates, provisioning profiles, and review issues. My approach: review your codebase and bug list, reproduce each issue, identify root causes, fix the code, test across modules, and provide clear evidence through screenshots, videos, and Git commits. I work well with existing teams using proper Git workflow and documentation. I can start immediately. Let's discuss the details. Thanks, Denis.
