GPS Jobs

Perdí por completo el código fuente de mi aplicación Android y solo conservo el APK instalado en algunos dispositivos. Necesito recuperar un proyecto íntegro en Android Studio a partir de ese binario, con todo el código legible, los recursos ordenados y la posibilidad de compilarlo sin errores. La app hace un uso intensivo del teléfono (gestión de llamadas y sensores) y precisa acceso al GPS para su funcionamiento principal, por lo que el proyecto resultante debe conservar esas llamadas a la API de Android tal como funcionan hoy. El trabajo consiste en: • Descompilar el APK con herramientas como JADX, apktool o equivalentes. • Reconstruir la estructura del proyecto (módulos, Gradle, recursos, firmas). • Limp...

I need a construction surveyor who can take full charge of the structural steel layout on a fast-paced commercial project just outside Atlanta, Georgia. The frame is going up quickly, so I’m looking for someone who already knows their way around robotic total stations, GPS units, and 3D laser scanners and can back that field expertise up with clean, defensible data inside AutoCAD or Civil 3D. Your field experience (at least three solid years) should include erecting structural steel, shooting column lines, and checking alignment before and after every crane pick. The superintendent will rely on your layout marks and as-builts to release fabrication and hold the erector accountable, so accuracy is everything—think ±1/16" on column centers and no surprises when the n...

Project Summary: Predictive Fainting Detection Bracelet I am developing a wearable bracelet designed to monitor physiological signals and provide an early warning when it detects patterns that may indicate an increased risk of fainting or loss of consciousness. The target users include individuals with POTS, vasovagal syncope, seizure disorders, and other conditions that can cause dizziness or fainting. Primary Goal The goal of this device is to help users feel safer and more independent, especially while driving. By detecting physiological changes that may occur before a fainting episode, the bracelet can alert the user early enough to safely pull over and seek assistance if needed. Core Features Heart rate and Heart Rate Variability (HRV) monitoring Blood oxygen (SpO2) monitoring Mot...

I am launching a complete ride-hailing ecosystem that mirrors Ola’s core experience and adds a few workflow tweaks of my own. The build breaks down into three interconnected products: • Android user app – must handle ride booking, live driver tracking and multiple payment options with the smoothness riders already expect from market leaders. • Android driver app – alongside standard ride-accept, navigation and history screens, the critical function is an automatic wallet deduction the moment a job is allotted, plus detailed earnings and trip analytics. • Web-based admin panel – a clean browser interface where I can monitor trips, manage drivers / users, adjust commission settings and inspect financial logs in real time. Both apps should talk...

I need a native iOS application that will let a user point the camera at a QR code, capture it instantly, and pull out the specific plain-text string embedded inside. As soon as the text is extracted, the app should check the phone’s current locale (or, if more reliable, the GPS-based country code) and show that text in the corresponding language. Core flow • Scan QR → isolate the plain text (no vCard, no URL parsing). • Detect language context automatically from device / location. • Translate and display the content in that language. Languages required at launch include Spanish, Chinese, and French, but the code must be structured so we can add any additional market language without refactoring the whole app. Technical notes – Built in Swift...

I have completed the schematic and multilayer PCB layout for a custom GNSS / GPS module that will sit inside a small-form-factor UAV. Before I press the “order” button, I need a second set of expert eyes to validate every critical detail, with extra attention on the power-supply architecture—which I flagged as my primary concern. The review should cover GNSS/RF trace routing, impedance control, grounding strategy, EMI/EMC risk points, component placement for manufacturability, and overall reliability under airborne vibration and temperature swings. If you spot an issue, I expect you to offer (and, if we agree, implement) concrete fixes so the board comes back right the first time. Design files are proprietary; I will share the Altium project after I see examples of ...

I'm working under Ramen Electric Pvt. Ltd., and I’m building a smart electric scooter project. I already have the mobile app UI and backend ready, but now I need the hardware side, plus help integrating it with the app. Here’s exactly what I need: A custom IoT PCB (ESP32-based) with: – GSM (SIM800L) – GPS (NEO-6M or similar) – Relay output for motor cut-off – Buzzer output – Optional UART/CAN to read data from LiFePO₄ BMS – Power input from 12V/5V DC I also need: – Firmware flashed on the board that can communicate with my app (Firebase/MQTT or REST API) – 1 to 2 fully assembled working boards shipped to me – Guidance on how to integrate the hardware with my app I will also share a document listing all the featur...

Design a modern, military-grade Convoy Tracking & Logistics Management Application that operates in both online and offline environments. The system must be built with an "Offline-First, Auto-Sync" architecture for use in remote, mountainous, border, and communication-denied regions. Core Objective Create a platform that allows headquarters, convoy commanders, and vehicle operators to monitor, manage, and track military or logistics convoys even when internet connectivity is unavailable. All tracking data must automatically synchronise with the central command system whenever network connectivity is restored. Key Features 1. Offline GPS Tracking Every vehicle continuously records: GPS location Speed Heading Timestamp Vehicle status Fuel level Cargo/inventory status Data must ...

I need someone physically present in Eritrea to confirm whether a provided address is accurate. During the visit, use a GPS-enabled camera (smartphone is fine) to capture 10-15 clear photos of the exterior, focusing on the building signage and the immediate surrounding area so that its context is unmistakable. When you are on location, take a Google Maps screenshot that shows your live position at the site. Make sure the timestamp and coordinates or map pin are visible. Deliverables • 10-15 geo-tagged photos of the building’s exterior, signage, and surroundings • One Google Maps screenshot taken on-site I will verify the metadata and map pin to confirm authenticity before releasing payment. Feel free to ask any logistical questions ahead of the visit so the trip ...

I need a focused Android mobile application that reliably captures and stores device location data. The core scope is limited to two key capabilities: • Real-time location tracking that updates smoothly in the foreground and, where possible, in background mode without draining the battery. • A searchable, timestamped location history that is saved locally and can be exported in a common format (CSV or JSON). I am not requesting geofencing at this stage, but the code structure should make it easy to bolt that on later. Feel free to use Google Maps SDK, Fused Location Provider, Room, or any comparable libraries you are comfortable with; just keep the dependencies mainstream so future maintenance is simple. Acceptance criteria – The APK installs on Android 10+ without...

I am looking for an experienced Android developer to build a GPS plotter and tracker application for marine/boating use in the Seychelles (Indian Ocean). The app will be installed and used primarily on a Samsung Galaxy S25 Ultra and must work fully OFFLINE at sea, where there is no mobile data coverage. KEY FEATURES REQUIRED 1. Live GPS position plotting on a map of Seychelles waters (Mahé, Praslin, La Digue and surrounding banks/reefs), with lat/long display in degrees-minutes format. 2. Offline maps/charts — the app must cache or bundle map tiles (e.g. OpenStreetMap / OpenSeaMap or similar) so it works with zero internet connection. 3. Waypoint management — create, name, edit, delete and categorise waypoints (e.g. fishing spots, reefs, hazards), with icons and colour ...

Our pipe-laying project is moving into a sensitive corridor and an environmental survey focused on soil and water quality is required before trenching begins. I need complete baseline data that can satisfy permitting authorities and give our construction team clear guidance on how to handle any contaminants or naturally occurring constraints. The scope covers: • Designing a sampling strategy that meets ASTM and local EPA guidelines for both surface and groundwater, as well as representative soil horizons along the right-of-way. • Collecting field samples with calibrated probes (pH, EC, turbidity) and GPS-referenced locations so the findings tie directly into our existing GIS alignment files. • Coordinating certified laboratory analysis for full chemical composition&mdas...

I need a clean, reliable mobile app that lets users open their phone, tap once, and instantly see the nearest Masjid on a map. The build has to ship for both iOS and Android from the same code-base, so please choose a framework you are comfortable with—Flutter, React Native or similar—provided the final binaries run smoothly on the App Store and Google Play. Primary goal • Accurate GPS-powered discovery of nearby Masjids, displayed with distance, basic details and directions. Project flow 1. Kick-off call to confirm tech stack, map provider (Google Maps, Mapbox, Apple Maps, etc.) and minimal UI wireframes. 2. Weekly test builds delivered through TestFlight and Google’s Internal Testing track. 3. Final submission includes full source code, build instructions...
