    II'm hiring an AI Video Producer to create cinematic YouTube videos that simulate “street interviews across time” (e.g., interviewing supporters of Booker T. Washington, W. E. B. Du Bois, and Marcus Garvey). The role involves generating historical scenes with AI, editing them into cohesive narratives, and adding voice, sound design, and captions. The goal is immersive, high-retention storytelling—not basic slideshows or template videos. You’ll collaborate on pacing, tone, and visual consistency to bring historical debates to life. Deliverables include fully edited 10–15 minute videos, with potential for ongoing work. Prior experience required. Example video below: Required Skills / Software AI Video Generation: Runway ML, Pika Labs, Sora-styl...

    I am launching a free volunteer-run English club in Tokyo Japan for elementary school kids age 6-12. The idea is simple: give kids a relaxed place to build confidence in every core English skill—speaking, listening, reading and writing—while also making new friends and having fun. Where I need your expertise is in turning this vision into a practical, well-structured program that volunteers can pick up and run smoothly week after week. The sessions will revolve around games, storytelling, arts & crafts, plenty of English singing and dancing, the occasional field trip, guest speakers, and even music or dance recitals. If you have experience designing ESL curricula for young learners, organising community events, or creating engaging, hands-on lesson materials, y...

    I need a reliable developer to turn my idea into a functional Android application. At this stage I only require a simple, well-structured MVP that can later scale as new features are defined. 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...

The core of this engagement is simple: you design a stream of bite-sized yet progressively challenging coding tasks, I complete them, and you review my work with clear, actionable feedback. My immediate focus is programming, 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.

Here is the new goal: whenever the application sends a message it must instead post to Africastalking’s bulk messaging REST endpoint ( ). All other behaviour in the app should remain untouched. I already own commercial decompilation tools and can provide you with a clean project skeleton produced from the executable, so you can focus purely on refactoring the SendSms() logic, wiring in the required headers, URL parameters

    I need a turnkey ...• You register or transfer in a clean domain, spin up an appropriate VPS, and install a mail stack (Postfix, Exim, or any proven alternative you prefer). • DNS is fully locked down—SPF, DKIM, and DMARC records propagate correctly and pass common tests. • The server is tuned for high-volume, transactional traffic with solid IP reputation practices (basic warm-up plan, rDNS, TLS, rate limits, queue management). • I can authenticate via SMTP (SSL/TLS, port 465 or 587) from my application and reach inboxes, not spam folders. • A brief hand-over document covers log-ins, basic maintenance, and scaling pointers. If you have experience launching high-throughput mail servers and keeping them compliant with major providers, I’m...

    ...performance, a minimal learning curve for the user, and an interface that feels modern on all current Android devices are all essential. Because the budget is tight, I want to keep the feature set focused: basic registration/login, one-to-one chat, push-style updates so new messages appear without manual refresh, and a small settings screen. I’m open to the stack you prefer—Kotlin with Firebase, Java with WebSockets, or another lightweight solution—so long as the result is stable and easy to maintain. Deliverables • Signed APK (ready for testing) • Full source code with clear comments • Simple but polished UI/UX assets • Brief setup documentation for future builds I value clear communication and quick turnarounds. When you reply,...

Originality is non-negotiable; every file will be checked in Turnitin and must show a negligible similarity score. No specific rubrics will be supplied beyond the individual questions, so please rely on accepted academic structure and depth appropriate for a master’s program. Deliverables • 20 standalone Word documents, one per assignment • Proper cover page, body, and reference list in each file • Average 1,000–1,500 words per assignment unless the question states otherwise • Turnitin report attached to every submission Acceptance Criteria • Each question fully answered with current, peer-r...

    I’m ready to commit to a focused weight-loss program and need a certified personal trainer who can guide me through effective, home-based fitness sessions. My main expectation is structured fitness training that targets fat loss while steadily improving overall conditioning and strength. You’ll design workouts I can perform in my living room with minimal equipment (think body-weight moves, resistance bands, light dumbbells) and meet with me live—either in person if you’re local or via video call if you work remotely. Here’s what I’d like to see from you: • An initial consultation (about 30 minutes) to discuss my current activity level, lifestyle constraints, and any movement limitations. • A customised weekly training plan that adapt...

    Sharpen A4 JPEG Printout
    4 days left
    Verified

    I have several documents saved only as JPEGs, and every time I send them to the printer the result looks blurred and muddy. What I need is a clean, crisp file that feels like it came straight from the original master copy when printed on standard A4 paper. The job involves taking each JPEG, removing the fuzziness, bringing back definition in both the text ...razor-sharp, the graphics should regain their contrast and detail, and nothing in the layout should shift. Once you finish, I’ll do a test print; if everything looks like a direct photocopy of an untouched original—no pixelation, no haloing around letters, no washed-out pictures—the job is complete. Please keep the colour profile and overall dimensions strictly at A4 so it drops straight into my print queue w...

    Retro Idle Game UI Overhaul
    4 days left
    Verified

    I’m giving the in-game interface of my browser-based idle game a full visual makeover and want it to scream retro pixel-art. The underlying logic is finished; all I need now is an eye-catching reskin. You’ll work directly in the existing Java back end and React/HTML front end, refactoring only the visual layer—layouts, components, sprites, colours, fonts, animations—while keeping every hook, state and API call intact. The Sprites and the UI-Elements are already existing and was created by me. Here’s what I’m after: • A cohesive pixel-art look inspired by classic arcade screens—bold palettes, chunky fonts, sharp contrast. • Clean React components and CSS that make future tweaks painless (feel free to vibe-code small utility com...
