...with equal attention to each channel. The spotlight is on short-form video—YouTube Shorts plus Instagram Reels and Stories—because that’s where I see the highest potential for quick audience gains. My single, clear metric for success is a steady rise in quality followers who are genuinely interested in my content. Here’s what I need from you: • A concise promotional strategy that plays to the algorithm strengths of each platform while keeping brand voice consistent. • End-to-end execution—optimised captions, hooks, thumbnails, hashtags, and scheduling—built around Stories/Reels and Shorts. • Smart use of paid boosts or influencer collaborations when organic reach alone isn’t enough. • Weekly insights: follower ...

Every week I drop a folder of raw vertical clips and expect them to come back as punchy 15-60-second YouTube Shorts that feel fresh, fast and built for the algorithm. The visual tone is trendy and visually appealing rather than comedic or tutorial-heavy, so pacing, colour work, and sound design all need to push the viewer to keep watching until the very last frame. Smooth, creative transitions are non-negotiable; they should stitch shots together in a way that feels native to TikTok/Reels culture without looking over-produced. If you have clever ideas for motion graphics, text call-outs, or light animation flourishes, feel free to suggest them—although the core brief is transitions first. I shoot in 4K 60 fps; you’ll receive the footage in a Google Drive folder along w...

...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.

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, please include links to two or three Android apps you’ve built tha...

...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 components if that speeds us up). • A revised HUD, pop-ups, progress ...

...promotions and shipping updates. Technical expectations • Develop in Kotlin (preferred) or Java, following current Android best practices. • Use a scalable architecture (MVVM or similar), with clear separation of concerns and easy-to-maintain code. • Connect to my existing RESTful API; handle authentication, pagination, and error states gracefully. • Ensure compatibility with Android 8.0 (Oreo) and above. Design direction I already have a basic brand palette; you will refine it and apply it consistently across the app. High-resolution assets and vector icons should be included so everything renders crisply on any screen size. Deliverables 1. Fully functional Android APK and source code hosted in a private Git repositor...

...during kickoff, but the visual direction must come entirely from a custom design created from scratch—no templates or off-the-shelf themes. Your process should cover UX wireframes, high-fidelity UI mock-ups, and the full Kotlin/Java codebase, all aligned with current Material Design guidelines while still feeling unique. Smooth performance, clean architecture, and well-commented code are essential because I plan to scale and maintain the app long-term. Deliverables: • Interactive Figma (or similar) design files • Compilable Android Studio project with source code • Signed release-ready APK/AAB • Brief setup & build documentation I’m ready to start as soon as we agree on milestones and timelines; please include e...

I’m open to your preferred stack (Python with PyPDF2/PDFPlumber, Java with PDFBox, or any robust alternative) as long as the final solution: • Runs on Windows 10+ without extra paid dependencies • Processes at least 200 pages in under two minutes on a standard laptop • Lets me update the template later without touching the core code (e.g., via an external JSON or simple GUI field map) • Outputs a perfectly flattened PDF—no editable form fields Please package the source code, a brief setup guide, and a short test report proving it...

My site is currently full of errors and the front-end visuals are all over the place. I need someone who can track down the faulty logic that’s breaking pages, and then smooth out the look so everything feels consistent and professional again. The website had a particular design and layout, and all of that should still be in there. You’ll need to go into the existing codebase, figure out what the issue and fix them so the site loads cleanly. Once the back-end is stable, I’d like the layout set to my original design so the interface looks polished across desktop, tablet and mobile and the visual layer renders consistently in the latest Chrome, Firefox and Safari. This should not be very time consuming or complicated, because the coding is already done and the design sh...

...organic traffic has suddenly fallen even though I have not rolled out any design tweaks or content updates for months. I can grant full access to Google Analytics (and, if you ask, Search Console) so you can dig into the numbers, spot patterns, and tell me exactly why the decline happened. What I need from you is a concise, data-driven report that: • Pinpoints the root causes of the drop (algorithm shift, technical error, on-page issue, backlink loss, etc.). • Outlines the evidence you found in Analytics and any supporting tools you prefer to use. • Provides clear, prioritized recommendations I can implement right away to regain and grow traffic. Please include in your bid the methods and tools you’ll rely on, the sections you plan to cover (techn...

I’m ready to turn my website into a steady source of local enquiries and bookings, and I need an SEO expert who can make that happen. My single, clear objective is to generate more leads from nearby prospects, so every tactic you propose should ultimately push qualified visitors to call, complete a form, or walk through the door. Google is the search engine that matters for me, so I’m looking for someone who knows its local algorithm inside out—think Google Business Profile optimisation, high-intent location-based keywords, locally relevant backlinks, on-page structure that highlights our service area, and conversion-focused content that answers real customer questions. Here’s what success looks like for this project: • A noticeable jump in lo...

...that spotlight Ronaldo’s goals and signature moments. The look I’m after is cinematic rather than chaotic—hard edits, smooth transitions, tasteful slow-motion segments, subtle motion blur, and light color grading that makes the red of the Portugal or Man United kit pop on small screens. Beyond the visuals, I’m aiming to grow the account to at least 5 k followers. If you understand Instagram’s algorithm shifts, optimal reel length, caption hooks, and hashtag stacking, your insight will be just as valuable as your editing chops. Advice on posting frequency, trending audio, and collaborations with similar sports pages will be welcome.

For my e-commerce store, I need the WhatsApp Business API set up end-to-end and then extended with a “coasting” flow that sends automated, algorithm-driven product recommendations to shoppers. Scope of work • Register and verify the WhatsApp Business number, configure webhooks, and upload the initial message templates so I can start sending approved notifications right away. • Build or connect an algorithm that selects products automatically—no manual curation—based on browsing or purchase behaviour and pushes those items through WhatsApp at the right moments in the customer journey. • Ensure the flow is compliant with WhatsApp’s commerce policy, allows easy opt-in/opt-out management, and logs message performance so I can tr...

I’m building a small stand-alone module around an ESP32 and need it to do one thing flawlessly: verify UPI payments made through PhonePe, google pay, bharat pay etc. The flow I have in mind is straightforward—customers scan a QR code, complete the transfer in their PhonePe app, and the ESP32 instantly confirms that the payment succeeded before triggering the rest of my system. What matters most is rock-solid transaction verification. The device must generate or display a QR code, listen for the incoming callback from PhonePe (or poll, if that is the only option PhonePe’s API allows), parse the response, and expose the result locally (GPIO change, serial print, or MQTT publish—I’m flexible on that detail as long as it is reliable). No receipt pri...

Brand identity Alongside the site, I need a logo that communicates professionalism and expertise while still echoing our vision of continuous learning and...

...clear call-to-action. Think smooth speed-ramped transitions, tasteful animated text that stays on brand, and a cinematic colour grade that keeps skin tones natural while giving the overall image depth. Layer in high-quality sound design—ideally a royalty-free track with subtle whooshes and hits synced to cuts—to lock down retention. Please optimise the file for Instagram’s current specs so the algorithm doesn’t punish reach, and keep export settings ready for quick repurposing on TikTok and YouTube Shorts. One round of tweaks after the first cut is enough; most feedback will focus on pacing and text timing. Deliverables: • Final MP4, 1080 × 1920, 30 fps • One eye-catching cover frame (JPEG) • Project file (Premiere Pro or DaVin...

...brochure I need a a few short-form video reels-for TikTok and for Instagram (vertical, 9:16). Each reel should feel native to the platform yet stay on-brand: quick-cut transformations, satisfying close-ups, and a closing overlay that mirrors the promo in the brochure. Reels can share the same raw footage; pacing and captions should be tweaked so the algorithm favours each platform. Deliverables: • Print-ready brochure file (PDF + editable source) • platform-optimised reels (1080×1920 MP4), plus captions/text layers I can update later • All linked assets (high-res photos, project blurbs, promo graphic) Acceptance criteria: • Brochure colour profile set for CMYK, 300 DPI minimum • Reels under 30 seconds, music cleared for commercial use...
