Über diesen Service
Do you need a web app to manage your business but don't want to pay thousands for a developer agency?
I build custom web apps using React, Supabase, and Vercel. Clean, fast, and deployed to production. I specialize in internal tools, CRMs, inventory systems, and CRUD apps that replace messy spreadsheets or outdated software.
What you will receive:
- Custom web app built with React and Supabase
- Authentication so only your team can access it
- Database designed and connected from scratch
- Deployed live on Vercel with your domain
- Clean UI your team can use without training
- Full code delivered so you own everything
This service is ideal for small business owners or founders who need an internal tool built fast without paying agency prices.
Message me before ordering and describe what you need to manage or track. I will tell you exactly what I can build for you.

I'm a Junior Data Engineer with hands-on experience in database design, data pipelines, and data-driven web applications.
I deliver ERDs, clean relational schemas, and documentation you can implement and maintain with confidence. I also work with dashboard data modeling, cloud pipeline planning, workflow automation, and building custom internal tools and client-facing apps.
Whether you need a solid database to build on, a pipeline to move your data, or an app to put it in front of your users, I can help you connect the dots.

FAQ
What technologies do you use to build the app?
I use Next.js for the frontend, Supabase (PostgreSQL) for the backend and auth, and Vercel for hosting. Modern, scalable, and with generous free tiers so you won't need expensive hosting.
Can I make changes to the app after delivery?
Yes. The code is clean, well-structured, and fully yours. You or any developer can modify it. Revisions are included in each package, and I'm available for ongoing support.
I'm not sure which package I need. Can you help?
Of course. Message me with a brief description of your business and what you need the app to do. I'll recommend the best package or create a custom offer for your project.

I hired him to build a custom app within Slack, and it was a great experience from start to finish. He made sure the app worked exactly as intended and thoroughly tested everything before and after delivery. Even after the project was completed, he remained available to answer questions and provide support...
