Hire the Best Payment Gateway Integration Specialists

Need a high-performance iOS and Android app without paying for two separate native teams? I build production-ready Flutter and FlutterFlow apps from a single codebase, so you ship to both stores faster, cheaper, and with one team instead of two. As a Top Rated Plus mobile engineer with a 94% Job Success Score and over $200K+ earned on Upwork, I turn complex backend systems into fast, fluid mobile experiences. Whether you need a brand-new MVP from scratch, an AI-powered app, or a rescue mission for a buggy legacy codebase, I write clean, scalable, architecture-compliant code that's built to last. 📱 See the proof, not just promises: I've shipped real, live apps you can download and test today, marketplaces, AI clinical tools, on-demand logistics, wellness, and education platforms. Check the portfolio section below on my profile to download them straight from the App Store and Google Play. ✅ Problems I solve for clients: "My app idea needs to launch on iOS and Android fast" → one Flutter codebase, both platforms, half the cost. "I have designs but no developer" → Figma-to-Flutter conversion into responsive, pixel-accurate UI. "I need AI features in my app" → speech-to-text, LLM/ChatGPT APIs, and automated data workflows integrated cleanly. "I need payments and subscriptions" → Stripe, in-app purchases, and billing systems done right. "My existing app is slow or buggy" → performance tuning, refactoring, and bug rescue on legacy code. "I need it on the stores" → full App Store and Play Store deployment and compliance handled end to end. 🛠️ Technical Stack: Mobile: Flutter, FlutterFlow, Dart, Kotlin, Java State Management: BLoC, Riverpod, Provider, Clean Architecture AI Integrations: Speech-to-text, LLM/OpenAI APIs, automated summarization Backend & Cloud: Firebase, Supabase, MySQL, REST APIs, SQLite, Azure DevOps CI/CD Native: Geofencing, background services, push notifications, Stripe & in-app subscriptions Design: Figma-to-Flutter, Material Design, responsive multi-device layouts 📈 How we'll work: A short discovery call to map your architecture, a clear scope and timeline, clean code with regular check-ins, and a tested app deployed to both stores. If this sounds like what you need, click "Invite to Job" at the top right, share your Figma files or requirements, and let's map out your build.

Most businesses don't need another developer. They need someone who can connect systems, automate processes, and build the missing pieces between them. That's what I do. My background is in Full Stack development and payment systems, where I've spent years building products, integrations, and business-critical workflows. More recently, I've been focused on automation and AI-powered systems that eliminate repetitive work and connect the tools businesses rely on every day. What makes me different from many automation specialists is that I'm not limited to no-code tools. When an automation platform reaches its limits, I can build the custom APIs, backend services, dashboards, and integrations required to make the entire system work reliably. Automation & Integrations n8n | Make | Zapier | AI Workflows | OpenAI Integrations | Webhooks | REST APIs | Business Process Automation Stripe Stripe Connect | Subscription Platforms | Marketplace Payments | Payment Flows | Webhooks | Billing Systems | Checkout & Customer Portals | Revenue Operations Automation Full Stack Development React | Next.js | Node.js | TypeScript | SQL | PostgreSQL | MongoDB | Backend APIs AI Powered Enterprise Solutions | AI Workflow Automation | Fintech Solutions | CRM | MVP | Mobile Application Development | Web Development Projects I Typically Help With - Lead management and CRM automation - AI-powered business workflows - Internal operations systems - Stripe billing and subscription platforms - Custom integrations between multiple SaaS tools - Workflow automation with custom backend logic - Customer onboarding systems - Marketplace and payment infrastructure - Reporting and operational dashboards One thing I've learned from building software is that automation is rarely about the automation itself. The real challenge is designing systems that are reliable, scalable, and easy for teams to operate. That's why I approach every project from a systems perspective first, then choose the right combination of automation tools, APIs, and custom development to solve the problem. If you're looking for someone who understands both automation platforms and the engineering behind them, I'd be happy to discuss your project.
