What I will provide • Brand guidelines, logo, and initial...

I’m upgrading my Roblox emergency-services roleplay experience and need a skilled Roblox developer who can handle both scripting and world-building. First, I want two working scripts dropped straight into the current game: • A car spawner that opens a clean vehicle-selection menu, lets players choose from our emergency fleet, and supports easy editing of spawn locations or model lists through a simple table so I can tweak it later without touching the core code. • A team changer that instantly moves players into Police, Fire, EMS or Civilians, updating uniforms and permissions the moment they switch. Beyond the code, I’m expanding the map. I have the base city ready; you will create a brand-new town on the far side of the map and link it with a multi-lane mo...

I already have working Android (APK) and iOS builds in hand. I simply need a developer who can guide them through the final stretch—add a couple of straightforward features I will outline, then get both apps live on the Apple App Store and Google Play Store using my existing developer accounts. Scope at a glance • Review the current codebase and confirm it compiles cleanly. • Integrate the basic feature set I will share (nothing heavy—think a minor UI tweak and one small functional add-on). • Re-build, sign, and submit the apps to each store, making sure they meet the latest review guidelines. • Hand over a short, plain-language walkthrough so I can repeat the submission process when future fixes are needed. Everything else—the design, main f...

iPad App (AR + LiDAR) for Measuring Wire Straightness and Length in Industrial Welding Robots Project Overview We are developing an iOS (iPad) application for industrial welding automation. The app should scan a welding wire/rod (default thickness 1.2 cm) using the iPad’s LiDAR or camera, analyze its real length, and detect how much it is bent (curved or molded). If the wire bend exceeds a defined tolerance, the app should alert the operator to replace the wire. Accuracy and reliability are key since this app will be used in a factory/robotic welding environment. Objectives 1. Use LiDAR / ARKit depth data to capture the 3D geometry of the wire. 2. Compute: • Actual wire length (in mm/cm) • Deviation or bend amount compared to an ideal straight line • Max dev...

I’m looking for a developer who can put together a lean, proof-of-concept mobile app that blends three essentials: • Workout & macro logging – users add exercises, sets, and daily nutrition in a clean, no-frills interface. • A content studio – users sort photos and clips into galleries and edit them on a simple timeline. • AI-assisted video editing – the app suggests cuts, highlights, and captions to speed up post creation. For this first milestone I only need the basics: a clickable, stable prototype with core screens, working data flow, and one demonstrable AI video-assist feature (even if it runs on a lightweight cloud model). Code should be readable, modular, and ready for future expansion. Cross-platform tools such as Flutter or Rea...

I’m looking for an Indian iOS engineer who can jump into my existing Swift-based social media app and roll out a round of user-interface enhancements. The core logic, APIs, and backend endpoints are already in place; your focus will be the front-end layer, making screens feel smoother, fresher, and more consistent with our current design language.
