SaaS & MVP Developer | React, Next.js, Python & AI Integrations

I help startups and growing businesses **turn product ideas into working SaaS applications, MVPs, dashboards, and web platforms** and improve existing products when they need new features, better performance, or a stronger technical foundation. I work across **React, Next.js, Python, Node.js, Supabase, PostgreSQL, APIs, authentication, payments, and AI integrations**, so I can take ownership of the product across both frontend and backend instead of being limited to one part of the application. Whether you are starting an MVP, extending an existing SaaS product, rebuilding part of an application, or adding AI to an existing workflow, I focus on building the features that matter to the product and its users. What I Build • SaaS products, MVPs & custom web applications • React, Next.js, Python & Node.js development • Dashboards, portals & multi-user platforms • APIs, databases, authentication & payments • AI/LLM integrations and intelligent product features • Existing product enhancements, debugging & optimization AI Product Experience I also integrate AI and LLM capabilities into SaaS and web applications when they provide a clear product benefit. This includes OpenAI and Claude integrations, AI assistants, document processing, RAG, structured outputs, intelligent workflows, and API-based AI features. The focus is not on adding AI for the sake of it. I look at where AI can improve the product whether that's automating a workflow, processing information, assisting users, or reducing manual work. Why Clients Work With Me ✓ Strong experience building SaaS products, MVPs and custom web applications ✓ Comfortable owning both frontend and backend development ✓ Can start from a concept, Figma design, existing codebase, or technical requirements ✓ Strong in APIs, databases, authentication, payments and third-party integrations ✓ Can add AI capabilities without unnecessarily rebuilding the product ✓ Comfortable working on both new products and existing applications ✓ Focus on clean, maintainable development and practical product decisions Technology Stack Frontend: React | Next.js | JavaScript | TypeScript | Tailwind CSS Backend: Python | Node.js | FastAPI | REST APIs Database: Supabase | PostgreSQL | MySQL | Redis AI: OpenAI | Claude | LLM APIs | RAG | AI Integrations Infrastructure: AWS | Vercel | Docker Integrations: Stripe | APIs | Webhooks | SaaS Integrations Best Fit I work particularly well with startups launching an MVP, SaaS companies building new features, businesses modernizing an existing application, and teams looking for a developer who can take ownership of a product feature from frontend through backend. Whether you need to build an MVP, develop a SaaS application, extend an existing platform, build a dashboard or portal, integrate APIs, or add AI to an existing product, I can help turn the requirement into a working, production-ready solution. Send me your product idea, existing application, Figma design, or requirements, and I’ll help map it into a practical development plan.
