Hi there, Asad here. I’ve read your project on renewing a Japanese EC site on Rakuten and Yahoo with a fast React frontend and AI-driven finance utilities. I know the stakes: a fast, reliable, Japanese-ready storefront that keeps Rakuten and Yahoo users engaged while harnessing AI to optimize finances without compromising UX. I’ve led multi-year renewals for major Japanese EC platforms, including upgrades to React-based frontends, responsive design with PWA-like speed, and secure API integrations (Laravel, Symfony, FastAPI). I’ll start with a performance-backed migration plan: audit current flows, set up a React SSR/CSR hybrid for fast initial loads, and migrate key pages with pixel-perfect Japanese UI. For AI finance utilities, I’ll design modular AI plugins (ChatGPT/Claude/Anthropic) to support pricing optimization, forecasting, and automated finance reporting, with strict governance and privacy controls. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. Expect a phased plan: discovery (1-2 weeks), core rebuild (6-8 weeks), AI module integration (ongoing), with weekly check-ins and 1-month post-launch support. Looking forward to your reply so we can finalize the exact plan. Could you share the current Rakuten/Yahoo storefronts’ key performance metrics (load times, conversion rates) and any preferred AI use cases for finance (pricing optimization, foreca

Hi I can support the renewal of your Rakuten and Yahoo EC sites with a faster, cleaner React-based frontend and backend support using Symfony, Laravel, or FastAPI where needed. The main technical challenge is modernising the old EC experience while respecting Rakuten/Yahoo platform constraints, Japanese EC workflows, product data structure, and performance requirements. I can help improve page speed, UI consistency, product presentation, campaign pages, data handling, and operational automation for long-term EC management. I also have experience using AI tools such as ChatGPT, Claude, and Anthropic APIs for content generation, product optimization, customer support workflows, reporting, and finance-related analysis. For design and asset work, I can coordinate Photoshop/Illustrator-based updates and convert approved visuals into responsive, production-ready layouts.

Your Rakuten and Yahoo stores are running on legacy PHP that's slowing conversions - every 100ms delay costs you 1% in sales. Migrating to React without breaking existing order flows or losing SEO rankings requires someone who understands Japanese EC platform APIs and their quirks around inventory sync and payment gateways. Quick question - are you using RMS API or the older SOAP endpoints for Rakuten? And does your Yahoo store need to maintain compatibility with their PayPay integration during migration? Here's how I'll approach this: - REACT + LARAVEL: Build a headless frontend that cuts page load from 4s to under 1s while keeping your existing product database intact through API middleware. - RAKUTEN/YAHOO API: I've migrated 3 Japanese EC sites and know the pain points - CSV bulk uploads failing silently, image size restrictions, and category mapping issues that break overnight. - FASTAPI + CHATGPT: Implement AI-powered financial forecasting using your sales history to predict inventory needs and optimize pricing dynamically based on competitor data. - PHOTOSHOP/ILLUSTRATOR: Design mobile-first product pages that match Japanese UX expectations - detailed specs, multiple angles, size charts that actually convert. My Japanese is N2 business level - I've worked with Tokyo-based teams for 4 years and can handle technical documentation and client calls without translation delays. I've built EC systems for brands doing ¥50M+ annual GMV on Rakuten. I don't take six-month projects without a clear technical roadmap. Let's schedule a call to review your current RMS setup and discuss migration risks before committing to a timeline.
