    I’m ready to launch a full website that will serve as a dedicated blog for educational content. The goal is to give readers a clean, engaging space to learn, react, and discuss—so a reliable user-comment system is essential from day one. Here’s what I need delivered: • A polished, responsive blog set up on a platform you recommend (WordPress, Ghost, or a similarly straightforward CMS—open to suggestions). • Intuitive post editor with categories/tags so I can publish lessons and tutorials without touching code. • Comment functionality that supports threading, moderation tools, and basic spam protection. • Thoughtful UX and visual design that reinforces an academic feel while staying lightweight for fast load times. • Core on-page SE...

    I need a full-fledged, customer-facing website for my SaaS startup that does one thing extremely well: explain our software features so end-users immediately understand the value and feel confident signing up for a trial or demo. The site should look modern, load fast on every device, and guide visitors through an engaging narrative—from a concise hero section to deeper feature walk-throughs, testimonials, pricing, and a clear call-to-action. I’m happy to discuss the stack, but a component-based approach (React, , Vue, or similar) combined with a lightweight CMS is my preference so my non-technical team can update copy and screenshots without developer help. Core objectives • Visually communicate the product’s key features in plain language, avoiding jargon. &b...

    The platform is already live in staging with an AI pipeline that produces unlimited, topic-specific maths questions, but it still needs a final engineering pass before launch. What I need you to focus on is the AI-generated maths questions themselves—ensuring they are accurate, varied, more efficient and clearly mapped to each learning objective—while also closing out the remaining LaTeX and skill and progress-tracking tickets with helping visualize it more for the student. LaTeX fixes • Remove instances of incorrect mathematical notation. • Correct poorly aligned equations so they centre properly inside our React components. • Eliminate inconsistent formatting across browsers (currently using MathJax). Skill-tracking refinement • Implement more d...

    My current lead-generation portal for school information runs on a stack, but the interface feels dated, performance metrics are slipping, and I need several modern features added. The goal is a complete rebuild that preserves existing data while delivering a smoother, faster, and more engaging experience.

    I’m building an online hub that lets accredited investors learn about, subscribe to, and monitor our real-estate fund—think of as the design benchmark, but with deeper data insight. The site must let users register, complete their profile, and immediately access a secure dashboard that shows current holdings, performance metrics, and downloadable reports. A key differentiator will be an AI layer that delivers predictive analytics on market trends and, based on those insights, suggests relevant investment opportunities from our pipeline. I need this engine to ingest reputable real-estate and macro-economic feeds, run the models, and translate the results into plain-language charts inside the investor dashboard. Everything has to feel natural on a phone. Whether visitors arriv...

    I need a clean, reusable code-base that I can clone any time I spin up a new online store. The blueprint has to ship with three core features already wired up—product search, a simple shopping-cart flow, and basic user account management—so I can focus on content rather than plumbing. Visual flexibility matters, but I’m happy to keep it simple: a small set of pre-defined color themes is enough as long as I can switch between them in one place (a config file or theme toggle). Every theme should automatically update buttons, backgrounds, text, and links without touching the underlying components. To help me present demos to clients, include placeholder assets: sample products with images and prices, a few generic logos, and short product descriptions. These can live in a...

    Jetman is launching soon and I want a polished, professional-yet-startup-friendly landing page that instantly communicates our value. To get every pixel right, I’d like you to begin with a high-quality Figma design before anything is coded. Here’s the flow I have in mind: a bold hero (headline, sub-headline, illustration, single CTA), 3–6 feature cards with icons, a simple “How it Works” stepper, a testimonials strip for social proof, an “About Jetman” blurb, and an email wait-list form that will later hook into Firebase or Mailchimp. Subtle micro-interactions or scroll-based effects are welcome if they enhance the experience without slowing the page. Visual tone • Professional and corporate rather than flashy, but still fresh enough to fe...

    JS Deployment on Hostinger via GitHub (Engineers & Vibe Coders) We are conducting a technical research project focused on the evolution of "Vibe Coding" and modern JavaScript deployment workflows.

Project Scope: - Workflow Documentation: You will provide a detailed technical breakdown of your current deployment pipeline from GitHub to Hostinger. - Community Contribution: Findings will be summarized and shared within GitHub Discussions to help standardize Host...

    My current app needs a fully-featured real estate search section. The core of the job is wiring up fast server-side rendered search pages with: • Robust property filters covering price range, number of rooms, square footage, date listed and any other common criteria, all working for Residential, Commercial and Land listings. • An interactive map (Google Maps, Mapbox or Leaflet—whichever you prefer) that syncs with the filter results and clusters markers for performance. • An area on each listing page where users can leave ratings and written reviews, along with aggregate stars shown in the search cards. The data layer is flexible (JSON file, REST endpoint or GraphQL); just expose clear TypeScript interfaces so I can swap in my final database later. Pages must st...
