I build production-ready Flutter and React Native apps for iOS and Android, and I specialize in one thing most developers avoid , cleaning up and scaling AI-generated codebases built with Lovable, Bolt, Cursor, or Claude Code. If your vibe-coded MVP works but needs a real developer to fix the bugs, restructure the code, and get it live on the App Store and Play Store , this is exactly what I do. What I regularly build: Secure authentication & role-based access Subscriptions, in-app purchases & payments Real-time features (chat, live updates, WebSockets) API-driven and data-intensive applications Clean, scalable architecture for long-term growth AI-generated MVP cleanup & production scaling I understand how AI tools generate code, where they cut corners, and how to turn an unstable MVP into a shippable product without rewriting everything from scratch. What clients can expect: Clean, maintainable code Honest timelines & daily/weekly progress updates Clear communication in plain English Smooth App Store & Play Store delivery Tech stack: Flutter, React Native, Firebase, Node.js, Laravel, REST APIs, databases, subscriptions, payments, and real-time systems.

I help founders and teams build and scale SaaS, Web applications, and AI apps from MVPs to production-ready systems that are actually used in the real world. I focus on building systems that are meant to be used, scaled, and maintained, not just delivered. With $100k+ earned and 90+ successful projects on Upwork, I focus on building reliable, scalable systems with clean architecture, not quick prototypes or short-term fixes. I don't do rushed MVPs with throwaway code. If you need something built fast, I'm probably not your person. If you need it built properly, so it actually holds up when users show up, let's talk. 🛠️ Core Expertise: SaaS Platforms & Web Applications: • SaaS platforms with dashboards, user roles, and scalable backend systems • Subscription systems, billing flows, and secure payment integrations • MVP development designed for real users and long-term scaling AI & Automation Integrations: AI is used where it adds real value (automation, workflows, intelligence), not as a shortcut to replace proper system design. • GPT-powered features, AI assistants, and Intelligent chatbots • AI-powered automation and workflow integrations to reduce manual work and errors Frontend Development • Fast, responsive interfaces using React, Next.js, and TypeScript • Modern UI with Tailwind CSS for usability and adoption • Performance-focused frontend architecture Backend & APIs: • Scalable Node.js backend, REST APIs, and real-time systems • Secure authentication, background processing, and microservices • PostgreSQL, MongoDB optimization ☁️ Cloud & DevOps: • AWS & GCP deployments, Dockerized microservices • High-traffic and data-heavy system optimization ⚙️ How I Work 1️⃣ Understand Your Goals – I analyze your product vision, user needs, and technical requirements 2️⃣ Build Reliable Systems – I deliver clean, maintainable, and production-ready code 3️⃣ Support Growth – I help optimize, scale, and improve your product as your business grows ✅ Why Clients Work With Me • 8+ years of full-stack development experience • 4100+ hours and 90+ successful projects on Upwork • Clear communication and structured execution • Clean, maintainable code (not quick fixes) • Systems built for long-term growth, not short-term delivery If you have a clear idea, or even a rough concept, feel free to reach out.
