There's a specific kind of full stack development that requires more than building screens and APIs. It's the kind where AI, sensitive data, complex business logic, and third-party integrations all need to work together inside a reliable SaaS product.
That's the kind of work I focus on. I build AI-powered SaaS products across healthcare, fintech, and other data-driven industries using Next.js, Nest.js, Supabase, GenAI, LLMs, and RAG.
AI SaaS is a major part of my work.
I've built AI features including LLM chat, RAG systems, document processing, AI search, workflow automation, structured data extraction, and AI assistants. I work across the full AI pipeline, from data processing and embeddings to retrieval, prompts, model integration, and the final user experience.
For RAG applications, I build the complete flow: document upload, text processing, chunking, embeddings, vector search, relevant context retrieval, and grounded LLM responses. I also focus on making AI features practical and reliable inside real SaaS products.
On the SaaS side, I build multi-tenant applications with secure authentication, user roles, dashboards, subscriptions, APIs, database systems, and third-party integrations. I use Next.js for modern web applications, Nest.js for backend APIs and business logic, and Supabase for PostgreSQL, authentication, storage, and Row Level Security.
Healthcare is another area where security and data privacy are especially important.
I've worked on healthcare applications involving sensitive patient data, AI-assisted workflows, medical document processing, healthcare analytics, and clinical workflows. I build with secure access controls, tenant isolation, audit logging, and careful handling of sensitive information.
I've also worked on fintech applications involving financial data, reporting, automation, payment workflows, and external API integrations where reliability and data accuracy are important.

If you're building an AI SaaS, healthcare, fintech, or data-driven product and need a full stack developer who can handle both the product and AI side, let's talk.
I can work with an existing MVP that needs improvement or help build a product from the ground up, from architecture and development to production.
