Senior React Native & Next.js Developer | Full-Stack & AI Integration

React Native and Next.js Product Architect building cross-platform mobile apps, web SaaS platforms, Python AI backends, and full-stack cloud systems (Node.js, Supabase, Firebase, AWS). I take total technical accountability to eliminate operational friction for founders. Most tech products don't fail because the idea was bad. They fail because of operational friction. A frontend freelancer ignores backend security. A mobile developer points fingers at the API. An AI developer builds a fragile script that breaks under real traffic. You end up managing a fragmented team, burning venture capital, and missing your launch window. I eliminate that entire problem. As your single-point technical authority, I bridge the gap between UI/UX design, cloud databases, mobile apps, and custom APIs—building your platform under one unified, scalable codebase. HOW WE WIN TOGETHER (THE PLAN) - Zero-Friction Cross-Platform Architecture I build iOS and Android apps using React Native and Expo while developing web SaaS dashboards in Next.js and React. Sharing state and business logic across web and mobile cuts build times by 40% without compromising native performance. - Production-Grade AI (Not Toy Wrappers) I design context-aware AI Agent Development workflows and secure Retrieval Augmented Generation (RAG) systems. Pairing Python and FastAPI with the OpenAI API, I connect LLMs directly to your private company data using enterprise security patterns. - Hybrid Backend & Database Engineering Whether leveraging rapid BaaS tools like Supabase and Firebase for immediate MVP speed, or engineering custom Node.js microservices and high-concurrency PostgreSQL hosted on Amazon Web Services (AWS), I build backends designed for scale, offline caching, and real-time syncing. - Codebase Rescue & Refactoring If previous developers left spaghetti code, fragile APIs, or unscalable database schemas, I take over. I audit your system, patch security risks, refactor the architecture, and push your release across the finish line. EXACT TECH STACK & CORE CAPABILITIES - Mobile App Development: React Native, Expo, iOS Development, Android App Development, Offline Caching - Web SaaS & Dashboards: Next.js, React, Web Application, TypeScript, SaaS Development - AI & Machine Learning: AI Agent Development, Retrieval Augmented Generation (RAG), OpenAI API, Python, FastAPI - Backend & Cloud Infrastructure: Node.js, Supabase, Firebase, PostgreSQL, Amazon Web Services (AWS), Software Architecture, API Integration If you are putting capital, revenue, or your market reputation on the line, don't leave your product to fragmented freelancers.
