Hi there, I’m a seasoned developer for large-scale, multi-device ecommerce platforms. I’ll build a modular backend with clean APIs, a responsive web app, and native Android/iOS apps that sync smoothly across devices. The plan includes secure payments, user accounts, and product reviews, plus admin dashboards, analytics, and robust security. Delivery follows a clear, phased path: architecture and MVP in 4-6 weeks, then feature sprints to scale with QA and performance optimizations. I will share portfolio examples and a milestone-driven schedule to give you confidence in progress and quality. Timeline: MVP ready in about 4-6 weeks; full platform 12-20 weeks depending on scope. Budget: around 700 USD with a discovery phase to lock scope and milestones; exact numbers finalized after kickoff. Technical questions I’d ask: What is your target MVP launch timeline and main regions? Which payment gateway(s) and currencies will be supported at launch? Single-tenant or multi-tenant architecture preference? Preferred hosting provider and tech stack? Must-have integrations (ERP/CRM/analytics)? Desired uptime and performance targets? How will product data be managed (imports, promotions, variants)? Security/compliance requirements (PCI DSS, GDPR, data residency)? Localization and accessibility needs (languages, RTL, WCAG)? What is your target MVP launch timeline and main regions? Best regards,
