I’m building “Baat karna,” a social-networking app that focuses first and foremost on real-time conversation.

The core deliverable I need from you is an instant-messaging module that supports one-to-one text chat plus integrated voice and video calls. Think WhatsApp-style call quality and speed, but without the extra bells and whistles for now. Media sharing and group chats might come later, yet they are outside the current scope—keeping the build lightweight and fast is my priority.

Key expectations
• Stable, low-latency text messaging
• Seamless voice and video calling with clear audio and reliable connectivity
• Clean, intuitive UI for chat and call flow (login, contact list, chat screen, call screen)
• Secure user authentication and encrypt...

iPhone Battery Management System inside-out and can work across software, hardware, and firmware layers to alter the way battery health data is reported. The goal is to change the internal metrics that feed the Health section in iOS so the device shows revised capacity, cycle count, and related statistics without triggering errors or safety lockouts. Can you make a Custom device that can be use on a factory level,hat helpful to change battery health and cycle by just connecting the battery BMS only. Scope • Reverse-engineer or otherwise access the BMS firmware and its data pathways. • Modify the algorithms or calibration tables that calculate battery health. • Validate the change on real hardware so the phone operates normally under charge, discharge, and idle state...

I have a clear idea of the problem my app should solve but, instead of a formal brief, I will give you a set of reference materials—competitor apps, feature lists, and a few rough sketches. Your first task is to study these assets, extract functional requirements, and translate them into a structured roadmap. Once we agree on the roadmap, you will design the UI/UX, recommend the most suitable tech stack (native iOS, native Android, or a cross-platform framework), and then build, test, and package the application. Code must be clean, well-commented, and committed to a shared repository so I can track progress in real time. Deliverables: • Requirement summary distilled from my references • Wireframes or a clickable prototype for sign-off • Full source code with bu...

Test builds, deployment support, and a brief user guide Acceptance criteria – All listed fea...

I’m looking for a seasoned Roblox developer who can turn a “Haystack”-themed simulator concept into a polished, live game. The core loop will centre on resource management and trading rather than the usual crop-click grind: players will gather hay, process it into higher-value products, and trade with NPCs or a dynamic marketplace to climb leaderboards. Here’s the vision so far • Genre: Simulator – no obby or tycoon mechanics unless they truly enhance the flow. • Theme: Haystack / rustic farming vibe with stylised barns, fields and machinery. • Gameplay focus: resource collection, tiered processing, upgrade paths, and an engaging trading economy that rewards strategic play. I’ll supply mood-boards, reference games and rough sketche...

I want to launch an Android and iOS application that mirrors the core experience of Bubbly Live—real-time streaming, one-to-one video calls, and virtual gifting—while still carrying my own branding touches. The interface should feel instantly familiar to regular Bubbly users, yet stand apart through subtle design tweaks that we will define together (think updated colours, iconography, and motion cues rather than a full layout overhaul). Core scope • Low-latency live streaming rooms that support thousands of concurrent viewers. • One-to-one video calling initiated either from a stream or directly from a user profile. • Gift-sending system with animated effects and a creator revenue share logic. • In-app wallet and consumable coin balance, including p...

I’m building Lume, an internal Roblox executor for both iPhone and iPad, and I want it to feel as seamless as the desktop tools serious scripters already rely on. At its core the app must load, parse, and run Luau that stays function-for-function in step with Roblox’s own interpreter, so that existing scripts execute without edits. The execution API has to be fully custom—no off-the-shelf wrappers—because I plan to expose it later to plugin authors. A polished, modern-feeling interface is just as important as the backend. I need a clean, touch-first layout with animated panels, syntax-highlighting text editor, dark/light themes, and responsive iconography that scales elegantly on every current iPhone and iPad resolution. Timeline: I want a demonstrable build insid...

I need a complete, production-ready mobile application (iOS and Android) that lets users hold Rupiah-based crypto assets, send and receive them seamlessly, and review a clear, immutable transaction history. From the same code-base I also want a built-in swap engine so users can exchange their Rupiah token for other coins, plus a lightweight point-of-sale module that merchants can run on a tablet or phone to accept the same assets at checkout. Security comes first, so please apply best-practice key management (encrypted local keystore, biometric unlock, optional hardware-wallet pairing) and audited open-source libraries wherever they fit. A crisp Flutter or React Native front-end is fine as long as the results feel native; Kotlin/Swift twins are welcome if you prefer. Because the supporte...

I need a streamlined mobile application that lets me run Garena Free Fire tournaments from start to finish. The app has to cover player sign-up, automatic bracket creation, real-time match results and push notifications so gamers always know when it’s their turn. A small admin area should let me open a new event, set rules, room IDs and prizes, then watch the leaderboard populate automatically as scores come in. Platform choice is flexible: a polished Android build, a native iOS version or a single cross-platform codebase all work for me, provided performance feels smooth and the UI reflects Free Fire’s style. I’d like the back-end kept simple—Firebase or any equally lightweight cloud stack is fine—as long as you hand over clearly commented source code and br...
