Next.js + Supabase Expert Needed to Fix Auth and Deployment Issues for Web App
I hired this developer to build an app for me and the experience was excellent from start to finish. Communication was clear, he moved quickly, and he consistently delivered exactly what he said he would.
What I appreciated most was that he actually thought through the product, not just the code. When something could be improved, he suggested better approaches instead of just blindly following instructions. That saved time and made the final product much better.
He’s also very strong when it comes to AI systems and RAG architectures. He clearly understands how to design and implement modern AI workflows rather than just stitching things together. That made a big difference for this project.
The quality of the work was strong, the turnaround was fast, and he handled feedback and iterations without any issues. Overall very professional and easy to work with.
I would absolutely hire him again and recommend him to anyone looking for a reliable developer who can execute quickly and deliver solid results.

Next.js SaaS Developer: Build B2B Ad Platform from Starter Kit
Working with Muhammad was a great experience from start to finish. He took our idea and turned it into a fully functioning app - no small feat - and did so with professionalism and skill throughout the entire process. What really stood out was how responsive he was whenever questions or issues came up. He never left us wondering where things stood. If you're looking for a developer who can take a concept and bring it to life, Muhammad is your guy. Highly recommend and very grateful for his support on this project.

Most AI projects fail between the demo and production. The agent works in a sandbox, the RAG pipeline pulls wrong context in the real environment, and the SaaS MVP that looked perfect in staging cannot handle actual users. That gap is what I close.
IBM and Meta certified |Top Rated. FinTech, MedTech, and EdTech.
Here is what I build and what it actually does for your business:
AI Agents and Multi-Agent Systems using LangGraph, LangChain, and CrewAI that execute real business workflows so your team stops doing manually what a system should handle automatically.
2. RAG systems that stop your AI from giving wrong answers to paying customers. Hybrid retrieval, re-ranking, and evaluation pipelines built on Pinecone, pgvector, and ChromaDB.
3. SaaS MVPs and multi-tenant SaaS platforms with auth, Stripe billing, role-based access, and admin dashboards that go live in weeks, not quarters.
4. AI workflow automation connecting n8n, Make, and Zapier to LLM backends that permanently replace manual processes across your operations
5. Production deployments on AWS, GCP, and Supabase with Docker, CI/CD, and observability built in from day one, not patched in after something breaks.
Two products I shipped recently:
Dandalee is a procurement SaaS platform for the Architecture, Engineering, and Construction industry. Built end-to-end on Next.js, Express.js, and n8n automation. It onboarded 2,000+ sellers, closed a $50K bridge round, and secured $1M in seed funding in Q1.
Doclatch is a HIPAA-compliant AI healthcare assistant built on LangChain and FastAPI. It parses unstructured medical documents, extracts clinical context, and generates structured staff task cards with source-level citations so every AI output is liability-proof for the practice.

If you are building an AI agent, RAG system, SaaS MVP, or full stack AI product and need it to work in production, message me with what you are trying to build. I will tell you in the first reply whether it is feasible, what the architecture looks like, and roughly what it costs. No sales call needed to get a real answer.
