The site must be visually engaging, easy to navigate, mobile-responsive, and — most importantly — feature a fully functional customer review system. Shoppers need to see star ratings and text feedback on every product page, and I want the ability to moderate or highlight reviews from the admin panel. Shopify, WooCommerce, or a custom solution in React / are all on the table as long as the final result is fast, SEO-friendly, and simple for my team to maintain. Payment gateways, product catalog management, and basic analytics hooks can be handled later; for this phase I’m laser-focused on the core storefront experience and the reviews module.

    ...need a cross-platform utility/productivity app built from the ground up and released on both the App Store and Google Play. The concept, detailed user flows, and screen-by-screen requirements are ready to share once we start; what matters now is finding the right developer to turn them into fast, stable code and a clean, modern UI. The build may use either a shared framework such as Flutter or React Native, or two native projects in Swift and Kotlin—whichever delivers smooth performance and keeps long-term maintenance straightforward. Expect standard productivity features like secure local storage, background sync, push notifications, and a concise onboarding flow. Analytics (Firebase or similar) and basic in-app settings must be integrated as well. Deliverables • ...

To start, I’d like to see: • A short note about the area you’re strongest in—writing, design, or coding—and one recent example link or attachment that shows your best work. • Your typical turnaround time for a task that takes you roughly one working day. • Your preferred tools or languages (e.g., Adobe CC, Figma, WordPress, React, Python, etc.). I assign tasks in clear, self-contained tickets and keep communication focused in Slack or email—whatever you prefer.

    Kendi markam için kullanıcıların cep telefonlarından rahatça alışveriş yapabilecekleri modern bir e-ticaret uygulamasına ihtiyacım var. En kritik beklentim, güvenli ödeme entegrasyonu (örn. Stripe, IyziPay ya da benzeri) ve satın alanların ürünlere yorum bırakabilecekleri şeffaf bir değerlendirme alanının kusursuz şekilde çalışması. Platform konusunda henüz kesin karar vermedim; iOS, Android veya React Native / Flutter gibi tek kod tabanlı seçenekler üzerine önerilerinizi duymak isterim. Kod mimarisinin ölçeklenebilir, tasarımın mağazamın kurumsal kimliğine uygun ve App Store ile Google Play yönergeleriyle uyumlu olmasını bekliyorum.

Preferred stack is flexible; Python with TensorFlow or PyTorch for the core model, plus React or an equivalent JS framework for the front end feels natural, but I’m happy to adapt to what you do best. We’ll agree on milestones, timeline, and specific tool choices together. Final deliverables: 1. Complete, well-structured source code with install/run instructions 2. Deployment scripts or Docker/K8s manifests 3. Technical and user documentation,...

    ...What I need from you spans the full development cycle: solid, well-commented code for data ingestion, preprocessing, model training, evaluation, and automated deployment; guidance on architecture and design choices as we iterate; and a polished, presentation-ready knowledge base that explains every component for future hand-off or scaling. A responsive web dashboard (built, for instance, with React or another modern framework) should graph live metrics, highlight anomalies, and push configurable alerts. On the back end, I expect a robust Python stack—think Pandas, scikit-learn, TensorFlow or PyTorch, plus Flask/FastAPI—to keep models retrainable and the API endpoints fast. Containerisation with Docker and optional orchestration with Kubernetes will help us stay cloud...
