Our current ad for The Proven Code Berberine looks and sounds amateurish. The audio is muffled, there’s background hiss, and the track cuts abruptly. Visually, the footage sits at a grainy resolution, transitions are harsh, and the overall storytelling falls flat. I need the spot re-edited from the ground up so it can finally represent the brand with polish and energy. Audio work comes first: clean and boost dialogue for clarity, layer in an engaging background music bed that matches our upbeat SaaS tone, remove any remaining noise, then add light sound effects to punctuate key on-screen moments. On the visual side, upscale or replace the low-resolution shots, smooth out every transition, weave in tasteful special effects or motion graphics, and restructure the sequence ...

Key needs: • Build a clean codebase for Android (latest SDK, Kotlin or Java—whichever you prefer). • Implement a straightforward UI with basic navigation and placeholder screens; final visuals can wait until the next phase. • Set up fundamental app architecture (MVVM or similar), user input forms, and local data storage so I can see real interaction on a device. • Provide clear instructions for running the project in Android Studio and generating an APK. I have not locked the app’s exact purpose yet, so I’m looking for someone who can advise on best practices, suggest lightweight libraries, and keep everything modular for future additions. If you value clear communication, clean code, and short turnaround times, I...

I have a set of annotated screenshots that capture every element of an existing TradingView strategy, but no source code. Your job is to translate those images into a clean, fully functioning Pine Script Strategy that behaves exactly like the original: same plots, same signals, same back-test results. You will receive the screenshots and a brief explanation of the intended logic as soon as we start. I expect: • A single .pinescript file written in Pine v5 • Settings, inputs and plots matching what appears on my charts • Comments in the code so I can follow the logic and tweak parameters later • A short note comparing your back-test metrics to the ones visible in my images to confirm the match Please send me a private message that includes at least...

...so languages such as Python, JavaScript, or Java are ideal starting points, though I’m open to others if you can show why they add value. Each task should highlight a distinct concept—data structures, algorithms, version control practices, test-driven development, or clean code techniques—so I can build a well-rounded skill set while producing tangible portfolio pieces. When you respond, please point me to past work that demonstrates your ability to teach, mentor, or structure learning projects; that will help me see your approach in practice.

I want a ready-to-play Java Minecraft modpack that recreates the money-making loop of the game “Mine Moguls.” The core gameplay should revolve around three pillars: players mine a variety of ores, sell those ores for currency, then spend that currency on progressively better gear and automated machinery. Gameplay & balance • Use the Create mod for all mechanical processing, drills, conveyers, crushers, and automated packing. • Handle the economy with Create : Numismatic so every ore automatically converts to coins that can be spent in in-game shops or vending machines for upgraded tools, belts, drills, and decorative add-ons. • Difficulty set to moderate: mobs and resource scarcity should challenge the player without feeling punishing.

I’m creating an Android-only application and need a developer who is equally comfortable in native Android (Java/Kotlin) and Python. The main objective is to connect a set of existing Python scripts to a clean, responsive Android front-end so the logic runs directly on the device. Here’s the current state: • All Python functionality is already written and tested on desktop. • No Android code exists yet; you will design the UI and wire it to the Python layer. • The bridge can be Chaquopy, Kivy, BeeWare, or any approach you prefer, provided performance on recent Android versions stays smooth. Scope of work 1. Set up the project structure and integrate the Python modules so they compile into the APK. 2. Build a minimal Android in...

Round-trip retrieval over IMAP and POP3 works using SSL on standard ports. 3. No open-relay or security vulnerabilities are reported by basic online scanners. If you stick to widely supported packages and best practices, the job should be smooth; I just want everything verified before sign-off....

...refreshing only the in-game HUD of our Java + React title and want every health and status bar redrawn as a horizontal, arcade-era pixel strip that feels as if it were lifted straight from a 1980s cabinet. The rest of the code base and gameplay loop stay exactly as they are; your work lives purely in the React UI layer and the sprite sheet you supply. Here is what I need you to do: • Design a cohesive pixel-art skin for the health and status bars, sized for 1080p but readable down to 720p. • Deliver the pixel sprites (PNG and source Aseprite/PSD) plus the accompanying React component that swaps the current SVG/CSS bar with the new artwork while preserving all existing props and data bindings. • Hand off any small helper functions or CSS tweaks necessar...
...documents—including API references, user manuals, and deeper guides—are complete on the content side but still feel rough around the edges. The main gap is consistent, elegant presentation of all code examples. Every snippet should sit inline with the surrounding explanation so readers never lose the narrative flow. Here is what I need done: • Work through each document, find the existing raw snippets, and re-format them to appear inline with proper indentation, line breaks, and styling. • Apply the same convention across every page so headings, bullet points, and cross-references line up cleanly with the in-text code. • Where syntax highlighting is possible in Markdown or similar, use it; otherwise rely on clear spacing and monospace fonts...

I recently migrated my point-of-sale to Square and now need the matching Square Online site so customers can place smoothie orders for pickup. My domain is already registered and the entire menu is in the Square inventory; what’s missing is the web front that pulls those items into a basic product list with a smooth checkout flow. The look should echo our shop’s vibe: rustic, earthy and naturally healthy. Think warm woods, fresh-fruit tones and clean typography that feels handcrafted rather than corporate. On the homepage I want our top smoothies highlighted as Featured Products and a small carousel of real Customer Testimonials to reinforce the community feel. I can give you access to the back end of our old website through WIX. Beyond drinks, the building hosts alternativ...
