I will develop your scalable web application or rest api backend
Anton Shvein
About this gig
Need a web application or API built, and want to talk to the engineer doing the work?
I design and build custom web apps and API backends: authentication, database design, third-party integrations, background jobs and deployment.
Elixir/Phoenix is my default stack. For anything else, message me first and I'll tell you honestly whether I'm the right fit.
AI is optional. I can build with AI coding agents under my review, or by hand with no AI at all. You choose. Either way you get tested code in your repository.
What you get:
- Working, tested code in your Git repository
- A README: how to run, configure and deploy it
- Fixed scope per package, agreed before work starts
I'm a systems architect with 15+ years in production systems, from telecom switches to iGaming platforms handling millions of events daily.
Message me with what you want built, your deadline and your preferred stack. I'll confirm which package fits before you order.

FAQ
Which stack will you use?
Elixir/Phoenix by default. If you need something else, tell me in your first message and I'll say whether I'll take it.
Do you use AI to write the code?
Your call. With AI, every change is reviewed by me before delivery. Without it, I write it by hand. The scope and price are the same. But without AI it needs more time.
Can you work in my existing codebase?
Yes, for Basic and Standard. Send me access or a read-only copy first.
Is my code confidential?
Yes. NDA-friendly, and all code is deleted from my machines after delivery.
What if the scope grows?
I'll say so before going over the package and quote the difference as a custom offer.
Who owns the code?
You do. It is delivered to your repository.
