Expert AI Full Stack Engineer for a SaaS Project

We are building a complex AI powered fintech SaaS platform and we need someone who truly knows their craft, not just another generalist who "knows PostgreSQL." This project involves advanced database architecture, multi tenant data modeling, high performance query design, real time financial data pipelines, and deep AI integration. If that sounds like your day job, read on. What we need from you: PostgreSQL at an expert level. Indexes, partitioning, query optimization, schema design for complex relational data, and you can talk about it in your sleep. React.js and Next.js for a clean performant frontend. You understand SSR, ISR, app router, and component architecture. Python for backend services, AI pipelines, and data processing. FastAPI or Django experience is a strong plus. Real AI integration experience, not just calling an OpenAI API and calling it done. To apply, share your portfolio or past work related to fintech, SaaS platforms, database heavy applications, or AI powered products. GitHub repos, live projects, case studies, whatever shows your depth. On our end, you will get full access to all project resources, architecture docs, prototypes, and MVP specs so you can hit the ground running with complete context. No guessing, no working blind.
