I build web applications, from production-ready SaaS platforms to AI-powered RAG systems and agents.

I’m a Software Engineer who works across both the product and AI layers. I build the application itself: frontend, backend, databases, APIs, authentication and deployment and can also design and integrate the AI layer when it makes sense.

What I build:
- Full-stack web apps & SaaS: Next.js, React, JavaScript, TypeScript, Tailwind
- Backends & APIs: Node.js, Python, FastAPI, PostgreSQL, MongoDB, Supabase
- AI applications: RAG systems, document Q&A, chatbots, AI agents & LLM integrations
- AI engineering: embeddings, vector search, AI workflows & tool-calling
- Authentication, payments & deployment: Clerk, Stripe, Vercel, AWS, Docker, Hostinger, DigitalOcean

- AI technologies I work with: OpenAI, Gemini, Anthropic Claude, Grok, Opensource LLMS, LangChain, LlamaIndex, Pinecone, pgvector, n8n, Vercel AI SDK.

How I work:
Clear scope → regular demos → clean, maintainable code → production deployment.
Tell me what you're building. I’ll be honest about the best approach, what’s actually needed, and whether I’m the right fit.
