Deliverables for each candidate you assess: • 60-minute video interview conducted on my platform • Real-time scoring against the rubric I provide • A concis...

I’m expanding a distributed team that delivers modern web applications for U.S.–based clients, and I need another full-stack developer who can jump in quickly and work 30+ hours each week for at least the next three months. Because many projects touch regulated data, U.S. citizenship is mandatory and you’ll be asked to confirm this during onboarding. The stack you’ll meet on day one is React on the frontend and Node.js/Express.js on the backend, so solid, hands-on experience with both is essential. If you also know TypeScript, Python, or Java—and have tinkered with Angular, Vue, Django, or Spring Boot—that versatility will come in handy, but React and Node.js are the core. I’m looking for someone who: • Has a minimum of two years of profess...

I need an Android application that allows users to send and receive funds quickly, track their full transaction history, and handle multiple currencies inside a single, clean interface.

I have an Android Studio project that needs some spring-cleaning before we add a small new feature. First, the housekeeping: • strip out any dead or unused classes, methods, and resources • refactor what remains so the codebase is readable, well-named, and lint-warning free • resolve a couple of known crashes and UI glitches Once that baseline is solid, I’d like a new dropdown on the main screen. It only has to show a static list that ships with the app—no dynamic filtering or server fetches right now—but please wire it so it can be extended easily later. The app is built with Kotlin (with a few legacy Java files), Gradle 8, minSdk 24. I’ll provide Git access and notes on the bugs I’m seeing. Deliverables • Clean compile with zero...

I need an external AI agent wired into that greets every new enquiry, leads a natural chat to collect our booking basics—shoot type, preferred date, location—and then shares the right service package, all while drawing on an already-prepared knowledge base to answer follow-up questions. The moment a lead proposes an exact date or asks something outside the predefined scope, the conversation must be handed over to a human without losing context. You will be building a hybrid system: clear rule-based steps for qualification and escalation, reinforced by machine-learning NLP so the agent understands free-form questions and keeps the tone friendly and on-brand. All data gathered in the chat has to flow straight into our CRM, and any outgoing email (quotes, confirmations, package ...

I need a self-contained plugin for Trust Wallet that adds full USDT support on both iOS and Android. The core features are straightforward: users must be able to send and receive USDT seamlessly, view an accurate transaction history (confirmations, timestamps, hash links), and enjoy the same security and usability they already have in the main Trust Wallet experience—no feature regressions. You’ll be working with the official Trust Wallet Core libraries, USDT ERC-20 contracts, and the mobile SDKs for iOS (Swift) and Android (Kotlin/Java). Clean integration is essential: the new module should slot into the existing wallet architecture so that balances refresh alongside other assets, push-notification logic keeps working, and any future wallet updates will not break the plugin. ...

I’m refreshing my brand and need two cohesive assets built around a clean, modern aesthetic: a distinctive logo and a print-ready brochure. The logo should work smoothly across digital and print media, so I’ll need the final artwork supplied in layered source files (AI or PSD), scalable vector formats (SVG, EPS), plus web-safe PNG/JPG versions.

I need a small yet rock-solid system that taps into my Binance P2P merchant account and automatically releases the crypto as soon as Google Pay confirms the buyer’s UPI payment. The whole point is to remove manual checks altogether—no timers, no button-clicks—just an instant hand-off once Google Pay flags the money as received. Here’s how I picture it working. A buyer initiates a trade on Binance P2P, sends funds through Google Pay, and the moment my UPI account registers the credit, your script pings Binance using their P2P API to release the coins. Speed and accuracy are far more important than fancy dashboards, but the code should log every step so I can audit transfers later and be confident nothing slips through. Native support for Google Pay is essential from...
