About this gig
Tired of developers who overpromise, disappear, or leave you with a halfbuilt app?
You have a real B2B or B2C AI SaaS product idea. Maybe you have even tried hiring before and got ghosted, received messy code you do not trust, or shipped something users do not actually want.
I help non-technical founders turn AI ideas into clean, launchable web apps and AI SaaS products, using ChatGPT or Claude, with a transparent process and codebase you actually own.
Here is what I focus on:
- Product first, tech second: We define the core use case, users, and success criteria before a single line of code.
- No black boxes: Clear architecture, readable code, and simple documentation so any competent developer can continue after me.
- De-risked build: Milestones, demos, and fast feedback loops so problems surface early, not at the end.
What you get:
- Concept and MVP scoping in plain English
- AI web app or AI SaaS with ChatGPT or Claude integration
- Basic analytics, admin access, and a short handover video
If I do not think your idea has a realistic path to a successful MVP, I will tell you upfront, before you spend a dollar on development.

My work has helped generate over $100 million in on‑chain value across more than 70 projects. I’m Karim, a blockchain engineer based in the Netherlands.
I partner with two types of clients:
• Non‑technical founders who want to launch and scale Web3 products without worrying about security or delivery.
• Technical teams who are strong in Web2 but need deep, battle‑tested Web3 expertise to ship secure, production‑grade blockchain features.
My role: be the Web3 lead you trust with the architecture, security, and implementation so you can focus on users, growth, and capital.

FAQ
I have an AI idea but no detailed spec. Can you help shape the product?
Yes. Most founders come with a concept, not a full spec. I help you clarify the core use case, user journey, and must‑have features, then turn that into a focused MVP that can actually launch and get traction.
How long does it take to launch an MVP?
Most MVPs for a single core use case take several weeks, not years. Timeline depends on scope and complexity, so after we discuss your idea I give you a realistic estimate and break it into milestones to keep things on track.
Can you support the product after launch?
Yes. After the initial MVP, I offer ongoing development in structured sprints so you can refine features based on user feedback, add new capabilities, and keep the product stable as you grow.
How do I know you will not disappear or deliver unusable code?
I work in clear milestones with demos, so you see progress early rather than at the end. You get access to the repo, clear documentation, and a recorded walkthrough so you are never dependent on me as a single point of failure. This structure directly reduces your risk because problems surface fast.
Who owns the code and IP?
You do. Once the project is paid for, you own the code, the architecture, and all project assets. I do not reuse your proprietary business logic in other client projects.
What tech stack do you use for AI web apps?
Typically a modern web stack (for example React or Next for the front end, a secure backend, and ChatGPT or Claude APIs for AI). I choose tools based on stability, speed to market, and how easy it will be for future developers to work with.
What if I am not happy with the direction during the build?
We avoid that by using small, visible steps. You see wireframes, workflows, and interim builds, and you give feedback at each stage. I would rather adjust early than ship something that does not match your vision. This is one of the simplest ways to increase your confidence in the project.
Will my data be safe when using ChatGPT or Claude?
I design around your data sensitivity. That can include not sending raw personal data to the model, masking fields, and limiting what is stored. We will discuss your data model upfront and I will explain, in plain language, what goes where.
