    I have a production-level mobile application built with Flutter. The backend services are written in PHP and connect to both MySQL and Microsoft SQL Server databases. The codebase is stable in day-to-day use, yet a handful of bugs still slip through and several new features are on my roadmap. Here’s what I need next: • Analyse the current Flutter code, identify reproducible crashes, UI glitches, or slow screens, and patch them without regressing existing functionality. • Extend the PHP API where required and make sure data flows cleanly between MySQL, MS SQL Server, and the app. • Implement a small set of new features that we will finalise together (for example, additional push notification logic or an upgraded authentication flow). • Document every change ...

    I need a skilled developer to build a streamlined, conversion-oriented website that turns visitors into customers. The site must load quickly, feel intuitive on any device, and guide users toward a clear purchase or enquiry action. I already have brand guidelines and copy ready to go; what I need now is the technical expertise to translate that material into a high-performing web experience. You should be comfortable choosing the most suitable framework or CMS, setting up secure payment or lead-capture flows, and integrating basic analytics so we can track conversions from day one. Clean, well-commented code is a must because I plan to maintain minor updates myself after launch. Key deliverables: • Wireframes or mock-ups for approval • Fully responsive front-end and back-end ...

    I have an existing live-streaming web app built with React.js on the client and Node.js on the server. The core pages already load, but several streaming-related components still need polish and, in a few cases, full implementation. I’m looking for someone who is comfortable jumping into a partially completed codebase, tidying up what’s there, then adding any missing pieces so viewers can watch streams smoothly and interact in real time. Here’s what you can expect once we start: • I’ll walk you through the repo structure, current routing, and the sections that already work. • We’ll review the current streaming layer together; if you feel another protocol (WebRTC, HLS, or RTMP) would serve us better, I’m open to your recommendatio...

    Browser Reflex Clicker Game (MVP) Budget: Starting from $30 NZD | Timeline: 3–5 days | Scope: MVP only Overview I need a simple, browser-based reflex/clicker game. Think the Chrome dinosaur game — lightweight, instant to play, no install needed. One endless round that speeds up over time, 3 lives, game over when all lives are gone. This is an MVP — working and playable is the goal, not a polished product. What I Need (MVP Scope) Gameplay: Enemies move toward a fortress on screen. The player clicks/taps them before they reach it. Each enemy that gets through costs a life. Lose all 3 and the game ends. Enemy Spawning: Single enemy type only. Enemies spawn at a fixed rate that gradually increases over time. Some randomness in spawn position and timing is fine, but nothing...

    I have a cloud-based Digital Signage Management Platform built with Flutter, Firebase, Firestore and Firebase Storage. The core features—admin dashboard, campaign and playlist scheduling, multi-screen remote control, and an Android TV player—are already live (you can preview the current demo at ). The next development phase is all about polish and stability, and my first priority is crystal-smooth video playback. Right now videos lag or buffer and certain streams don’t behave consistently on Android TV devices. Because the system displays both videos and images in rotation, even a momentary stutter is noticeable on-screen, so I need someone who knows exactly how to squeeze every drop of performance from Flutter’s rendering pipeline and from Firebase’s media...

I have already created the Firebase project and will share the API key as soon as we start. What I need you to wire up: • Authentication – enable phone-number OTP login alongside the classic email-and-password flow, making sure both methods land in the same user collection. • Firestore – create tidy, scalable collections for:  – user profiles (name, profile picture URL, bio)  – posts (text or image URL) with sub-collections for likes and comments • Storage – configure buckets and folder paths for profile photos and uploaded post images, then surface the download URLs back to Firestore. • Basic security rules ...
