AI SaaS & Fintech Developer | Next.js, React, FastAPI

I build AI-powered SaaS platforms from lean MVP to scalable multi-tenant products using Next.js, React, TypeScript, and Python/FastAPI. If you need working software your team can actually ship and extend, not a weekend prototype, that's what I deliver end to end: architecture, backend, frontend, and the AI layer that makes the product different. ✅ AI-Powered SaaS Development OpenAI / LLM API integration into production web and SaaS products Multi-tenant architecture: authentication, role-based access control, subscription & billing (Stripe), admin dashboards AI-driven analytics, recommendation engines, and content-generation workflows (text, image, video) Real-time data pipelines and third-party API integrations Containerized deployments (Docker) with CI/CD pipelines on AWS Core stack: Next.js, React, TypeScript, Node.js/Express, Python (FastAPI, Django), PostgreSQL, MongoDB, Supabase, Firebase RESTful API design & integration ✅ Proven in fintech & real-time trading platforms Built Trade Athletes (Players FX), an athlete-stock trading platform, end to end Built Pick Fantasy, an AI-powered fantasy sports trading exchange Comfortable with the compliance, real-time pricing, and transaction-integrity demands specific to fintech products ✅ Native Android, when the project needs it Need a companion mobile app alongside the web platform? I build those in React Native — MVVM architecture, REST API integration, local storage (Room/SQLite), push notifications, Play Store deployment. ✅ Why clients work with me Top Rated freelancer, 100% Job Success Score Average response time under 4 hours Clean, maintainable code and proper version control built to be extended, not rewritten in six months Regular updates and honest timelines, so you always know where the project stands If you need a SaaS product, an AI-integrated platform, or a fintech application built from the ground up, send me your project details and I'll tell you honestly whether it's a good fit and how I'd approach it.
