About this gig

Hi, I'm Haris a full stack developer and product manager with 8+ years of experience building AI SaaS and web applications.


Most "AI integrations" you see online are surface-level wrappers around ChatGPT. I build production-ready AI SaaS products that actually scale, with clean architecture, proper auth, prompt engineering, and real UX.


WHAT I'LL BUILD FOR YOU:

- AI chatbots, agents, and assistants powered by OpenAI or Claude

- RAG systems with vector databases (Pinecone, Supabase)

- Full SaaS platforms with auth, payments, and dashboards

- AI tools that solve real business problems, not just demos


TECH STACK:

Next.js, Node.js, React, TypeScript, OpenAI API, Claude API, LangChain, PostgreSQL, AWS, Vercel, Stripe.


WHY WORK WITH ME:

- 8+ years building real products, not just prototypes

- Product management background I understand what makes a SaaS actually convert

- Clean, scalable, documented code

- Honest timelines and clear communication


BEFORE YOU ORDER: Message me with your project details so I can scope properly and send a custom offer if needed. Most real AI SaaS builds need a tailored quote.


Let's build something great.
