    I need a fully explorable 3-dimensional map of Hyderabad’s Hitech City, covering roughly a 5 km stretch of its main streets and recognisable landmarks. The style must stay true to life—textures, lighting, and building proportions should feel as if the player has been dropped right onto the actual road. A single protagonist will spawn on the map in third-person view. Movement and camera control have to run through virtual, on-screen touch controls, much like the layout you find in PUBG Mobile: a left-side joystick for motion, right-side swipe for camera, plus basic run and jump buttons. Smooth 60 fps performance on mid-range Android devices is important. Deliverables • Optimised 3D environment of Hitech City (5 km) with collision, LODs, and baked lighting. • Rigg...

    I want an app that scans the phone’s camera roll, recognises the same person across different shots, and then lets me decide exactly which images to forward. The core flow is simple: • First, the app analyses every photo, clusters faces that it believes belong to the same individual and shows me those groupings. • From there, I can pick pictures one-by-one or bulk-select them in three distinct ways: individually, by date range, or by geolocation. This mirrors the way I already think about my library, so the interface needs to surface those three filters prominently and let me combine them if I wish. • Once I have a final selection, the app should open the standard share sheet so I can send the chosen files through any installed channel (Messages, WhatsApp, AirDrop...

Think World of Warcraft’s third-person feel, but stripped down to the essentials—no progression, inventory, or persistent accounts. Core play loop • Players pick one of two visually distinct factions; mechanics stay identical. • Each faction offers a Tank (melee + defensive skill) and a Ranged DPS (projectile attack + burst skill). • Health management, ability cooldowns, and a central capture point with a progress bar decide the winner. A match ends when the timer runs out or a team fully claims the objective. Tech & scope • Pure Unity project—host-client architecture is fine. • Online networking can rely on...

The core work is twofold: first, bring every gameplay mechanic over so it runs flawlessly on the newer engine flow on the latest UI toolkit. No new features are required; this is a straight upgrade focused on compatibility, stability, and a polished feel in the updated environment. I expect you to handle any API changes, package replacements, shader or lighting tweaks, and input-system updates that Unity 6 now enforces. Final delivery is the upgraded Unity 6 project folder ready to open, build, and release version. In this time run in android, need to work with Windows and WebGL too.

When a user taps a pad, the assigned audio file—MP3, WAV or FLAC—must play instantly and cleanly. Pad should have two modes: one-shot and looping toggle. No additional processing such as reverb or an equalizer is required; keeping latency low is the priority. The grid itself is fully customizable: users decide how many rows and how many columns they want, then assign colors and labels to each pad. All of that, together with the file bindings and an individual volume level per pad, should be saved into named presets that can be loaded or shared later. Preset data should be stored in human...

    I’m expanding our mobile team and want an experienced developer who is equally comfortable in Flutter (Dart) and React Native (JavaScript/TypeScript). Our live products run on both iOS and Android, so every feature you tackle must compile cleanly and perform smoothly on each platform from the first build. THIS JOB IS IN THE US TIME ZONE ONLY + NEED WEEKEND AVAILABILITY The initial assignment is urgent—bug squashes and a small new module need to ship ASAP—yet the larger goal is an ongoing collaboration. Once we clear this immediate milestone together, you’ll roll straight into our regular sprint cycle, building new screens, integrating REST/GraphQL APIs, writing unit tests, and taking part in code reviews on GitHub.

    I want to launch a single mobile app that lets drivers handle every routine task around their vehicle without ever leaving their phone. The build has to be truly cross-platform—one code-base deployed to both iOS and Android—so users on either store get the exact same experience. Core modules I need right now are: • Check car details pulled live from the Vahan API • Pay traffic challans seamlessly inside the app • Recharge FASTag in just a few taps • Full buy-and-sell marketplace for used cars For the Vahan integration you’ll work with the official APIs to fetch RC details securely. Challan and FASTag flows will require payment-gateway integration (UPI & cards) and receipts stored in the user’s history. The marketplace should let any...

    I need my existing OTT streaming app for iOS enhanced with a proper onboarding flow. Right now users go straight to the home screen; I want to introduce: • Email-and-password registration with verification (Like Netflix) • One-tap Google sign-in, using the official Google Sign-In SDK and complying with Apple Sign-In fallback rules The project involves wiring the new credentials to my current backend (Node/Express with JWT), adding the required UI screens in Swift/SwiftUI so they match the rest of the app, and ensuring smooth navigation from splash screen to the new sign-up / sign-in choices. A few minor visual touches are also needed on those new screens so everything looks consistent with our existing palette and typography, but no full redesign is required. Apple Pay/ Razor...

    Our landscape construction firm juggles dozens of jobs at any given time, and I need a cloud-based system that tracks each project from the first bid through final hand-off. The core will sit on Firebase so the team can enjoy real-time updates wherever they are on site or in the office. What I need you to build • A relational structure in Firestore that clearly separates bidding, construction, and close-out data yet lets us call up every contract, invoice, plan, or photo in seconds. Documents themselves should live in Firebase Storage, linked back to their parent records. • Robust, role-based user access: estimators see bids, project managers see active jobs, finance sees invoices, and admins see everything. • Instant synchronization so two people never overwrite each...

    I need a production-ready chatbot I can license or resell to different clients. Its core role is real-time customer support, but it also has to handle FAQs, simple bookings, and any other routine queries that typically swamp a help desk. Integration scope The same bot must plug seamlessly into websites, native mobile apps (iOS and Android), and major social media channels (Facebook/Instagram, WhatsApp, etc.). I’m open to middleware such as Dialogflow CX, Microsoft Bot Framework, or a custom Node/Python stack—whichever you can prove will scale cleanly across all three environments. Key capabilities • Multilingual support: automatic language detection and translation so end-users get replies in their own language without manual routing. • Analytics & reporti...

    1. Description: The Residential "Digital Twin" We are building a Web-First Interactive Portal for residential homeowners. The platform allows owners to visualize their home’s construction by pinning photos and documents directly onto their architectural floor plans. The app acts as a "Digital X-Ray," capturing what is behind the walls (plumbing, electrical, structural) before they are closed. It provides a simple, high-resolution interface for the owner to track progress and manage Variation Requests(Change Orders) and defects (punch lists) in one geographically organized hub.
