I need a texture pack for Minecraft Java. Items, UI/tools, fonts, and everything else in the provided file must be accurately converted to a Bedrock texture pack. This is a personal project for myself and my friends that requires server hosting. ps: I tried almost every web/app/bot conversion tool for Java to Bedrock Pack, and they all failed. It appears that there is a technical issue with my plugins, or that something is interfering and preventing the Bedrock texture pack from loading. It actually downloads the pack but does not load for Bedrock players. So I need a professional who is knowledgeable about server hosting, configuration, and development to accurately resolve this issue. I've done a lot of debugging with the latest AI tools and docs, but they still couldn...

Core deliverables I expect: • A brief technical blueprint or architecture summary once the scope is clarified • High-fidelity UI mock-ups or prototypes (Figma, Adobe XD, or similar) for approval • Well-structured Android source code checked into Git with meaningful commits...
I need a reliable, long-term supply chain for three fast-moving product lines: Cadbury (chocolate bars, confectionery and beverages), KitKat (original bars, flavoured bars and multipacks), Biscoff biscuits and bread spread and Wesson cooking oil. My immediate priority is to secure distributors or wholesale partners that already ship sizeable volumes within the EU, the US and the broader MENA region, and who can offer factory-fresh stock with export-ready documentation. What I’m looking for • Verified distributor or wholesaler contacts able to quote on full-container or pallet quantities. • Current price lists that include MOQ, case counts, shelf-life and Incoterms (EXW, FOB, CIF or DDP). • Evidence of brand authorisation or a proven track record handling Cadbury...
...of Forge, Spigot, and Fabric is essential. You’ll handle: • Troubleshooting server issues – reading logs, reproducing bugs, and applying fixes • Setting up and optimising mods, plugins, and entire modpacks • General technical support and player assistance, keeping explanations clear for less-technical users Because most questions are advanced, I need someone already comfortable with Java stack traces, allocation tuning, and cross-platform quirks (Windows, Linux, and sometimes Mac). Familiarity with popular panels such as Pterodactyl, Multicraft, or similar is a plus but not mandatory; you will, however, be expected to work entirely through Discord. Deliverables are simple: resolved tickets with satisfied customers and a brief note of the fi...

... Because this product targets individual consumers, the interface has to be clean, mobile-friendly, and guided by simple onboarding flows. Real-time balances, instant deposits or withdrawals, and at-a-glance portfolio insights sit at the heart of the vision. I’m open to the tech stack you’re most productive with—whether that’s React Native or Flutter on the front end, a robust Node, Python, or Java back end, and cloud deployment on AWS, GCP, or Azure—as long as you can demonstrate prior success shipping production-ready fintech features. Timeline is critical; I need to see an MVP running ASAP, so efficient sprint planning and clear communication are essential. Deliverables (acceptance criteria) • Fully functional web and/or mobile app c...
I need a focused deep-dive into my site’s traffic sources so I can see exactly where visitors come from, how each channel performs, and where hidden opportunities or waste may sit. Tool choice is still open—Google Analytics, Adobe Analytics, or Matomo are all on the table—so part of the assignment is advising on which platform (or blend of them) will surface the clearest insights. Primary focus Traffic sources are the cornerstone of this project. Please trace every referring medium (organic, paid, social, direct, email, affiliates and any others you uncover), quantify their contributions, and highlight patterns such as seasonality, campaign spikes or sudden drops. If your analysis naturally reveals meaningful user behavior patterns or conversion rate findings, feel fre...
I already have a clear intraday equity strategy sketched out on paper and now need it translated into a working Tradetron algorithm. The logic relies primarily on time-based conditions rather than classic price-action or technical indicators, so you should be comfortable building entry, exit and risk-management blocks that trigger strictly at specific market times. Here is what I’m expecting: • A complete Tradetron strategy file that I can import directly, including all legs, position sizing, stop-loss and target rules. • A brief walk-through (video or call) showing how each time condition is wired so I can tweak parameters myself later. • One round of post-deployment adjustments after I run the strategy in paper trading for a day. If you have previous T...
...want an independent pair of eyes to be sure everything under the hood is as solid as it looks on the surface. My in-house developers followed our own internal standards while building the project; however, those rules live mostly in our heads rather than in formal documentation. That means I need someone who can dive straight into the source, interpret our style from context, and benchmark it against recognised best practices. The audit has three clear pillars: code quality, performance, and security. I expect a thorough review of the Dart/Flutter codebase, dependency tree, build configuration, and native platform integrations. On the performance side, I’m looking for concrete findings backed by profiling data—startup time, rendering speed, memory usage, and a...

...custom TradingView indicator (Pine Script V5) that integrates several advanced trading methodologies into a single, cohesive tool. Project Requirements: 1. Strategy Integration: • ICT (Inner Circle Trader) & SMC: Automatic detection of Market Structure Breaks (MSB/BOS), Change of Character (CHoCH), and Order Blocks (OB) with volume validation. • Elliott Wave Theory: An automated wave counting algorithm (Waves 1-5 and ABC correction) based on price action and momentum. • Harmonic Patterns: A scanner for all major patterns (Gartley, Bat, Butterfly, Crab, Shark, Cypher) both Bullish and Bearish, with Fibonacci ratio labels. • Classical Analysis: Integration of support/resistance zones, trendlines, and chart patterns (Head & Shoulders, Double Top/Bottom). ...
...detailed view when an item is tapped. • Data — mock or lightweight local data is fine; the list should surface service details and product listings so I can validate usability. I care far more about clean, scalable Kotlin (or Java) than fancy visuals. A straightforward MVVM/Repository setup in Android Studio, Jetpack libraries, and sensible naming are what I’ll review first. If Compose accelerates you, great—otherwise classic XML is acceptable. After an initial chat I’ll share the rest of the technical notes, but the deliverable I’m expecting is: 1. Source code in a private Git repo with clear README instructions. 2. An installable debug APK that shows the search-filter-detail loop working smoothly on Android 8+. I&rsquo...
...completely non-custodial: every product a vendor lists carries the vendor’s personal XMR address, so payments flow directly to them. On the customer side the flow is simple—browse, add to cart, pay the provided Monero amount, and leave with a unique order ID they can use to track their orders with. Key points I need covered – Direct Monero payment integration only. No third-party gateway; the code should watch the chain (or use monero-wallet-rpc) to confirm incoming TXs and update order status automatically. – Vendor portal featuring product listing management, order tracking, and a lightweight sales analytics view. Vendors also need fields to save their XMR view key and a PGP key so customers can encrypt shipping details. – Recurring vendor su...
The open-source repository at still compiles, but the actual chat layer is broken. I need someone to dive into the existing code and bring the peer-to-peer conversation flow back to life. What matters most to me: real-time messaging that uses PEX (peer exchange), reliable chat-history loading on start-up, and checksum-based verification so every stored message can be trusted. Deliverables • Fully working real-time chat between peers, demonstrated with two or more fresh installs. • On launch, the client reads the saved chatlog; on shutdown or new message, it persists it. • Each history is accompanied by—or internally stamped with—a checksum; mismatches must trigger a clear warning.

...comments—all delivered with a clean Material Design interface and smooth performance on modern Android devices. You’re free to choose Kotlin or Java, but the code must be written in Android Studio, clearly documented, and structured for easy hand-off. For authentication and cloud storage I’m leaning toward Firebase, yet I’m open to your technical suggestions if they simplify scaling and keep costs reasonable. Security, responsive layouts, and thorough testing are essential; I’d like the first APK to be stable on Android 8.0 and above and ready for submission to Google Play. Deliverables • Complete Android Studio project with readable source code and compiled release-ready APK • Basic technical documentation (b...
I have twelve floor-plan PDFs that show every workstation in the building. I need each file reviewed, every desk counted, and the map divided into visual sections of roughly 100 desks apiece. Once the groupings are set, apply a distinct outline color to each section so it’s obvious where one block ends and the next begins. Exact counts aren’t required—an approximate target of one hundred desks per color block is fine. Feel free to choose any palette as long as neighboring sections are clearly distinguishable. When you’re done, return the updated PDFs plus a simple spreadsheet that lists, for every color on every floor, the desk total you arrived at. Accuracy in counting and a clean, professional look on the final visuals are the key success measures. Acrobat, Blue...
I have a small AGV platform running on an Arduino Uno, two DC motors driven by an L298N bridge, and a pair of HC-SR04 ultrasonic sensors mounted up front. I already have the hardware wired and tested; what I still need is clean, well-documented embedded-C code that lets the robot detect an approaching obstacle with the ultrasonics and autonomously steer around it. Functionality • Primary mode must be obstacle avoidance; no line following or remote-control features are required at this stage. • When the sensors report an object within the safe-distance threshold, the robot should smoothly adjust course and continue forward rather than simply stopping. A simple state machine or PID-based turning logic is fine as long as the movement looks deliberate and repeatable. Imp...

It is a long-term, enterprise-level platform that will power customer applications, driver operations, admin systems, inventory flows, order lifecycles, payments, and real-time delivery tracking. The backend APIs will be the core foundation of the entire business. The backend system must be developed strictly using Java and the Spring ecosystem (Spring Boot, Spring Security, Spring Data, Spring Cloud where required) and follow a microservices-based architecture. All services will communicate through secure, well-documented REST APIs, using internal JWT-based authentication and industry-standard security practices. We are looking for freelancers who can take ownership of backend services end-to-e...

I need a skilled Java developer to turn my desktop-application idea into a working program. The core requirement is straightforward: the finished app has to run reliably on Windows and macOS, install easily, and offer a clean, intuitive interface. You are free to pick Swing, JavaFX, or another modern Java UI toolkit as long as the end result feels native and responsive. I will share mock-ups, a concise feature list, and sample data once we start. What I expect back is the complete, well-commented source code plus a packaged executable (JAR or native installer) that passes a quick smoke test on both operating systems. If you’ve built polished desktop tools in Java before, I’d love to see one or two examples along with a brief note on the fram...
