I will develop scalable web application or api in elixir, phoenix and ash
Anton Shvein
About this gig
Need a web application, JSON API, REST API or GraphQL API built in Elixir and Phoenix? Start with one bug fix or one endpoint.
I build and fix Phoenix LiveView apps and JSON, REST and GraphQL APIs on PostgreSQL, using Phoenix, Ecto and Ash Framework. Every package ends with tested code in your Git repository.
What you get:
- Working, tested code in your repository
- A short README: how to run, configure and deploy it
- Scope agreed before work starts
Typical work:
- Basic: a bug fix, a small change or one endpoint
- Standard: a feature or up to 5 API endpoints with auth
- Premium: a small MVP, new app or module with up to 5 screens or resources
- Extending or rescuing an existing Phoenix codebase
Basic covers one small, clearly defined task. It is not a full application. Bigger work fits Standard, Premium or a custom offer.
I'm an Elixir/OTP architect with 15+ years in production systems: telecom, crypto and iGaming platforms handling millions of events daily.
Message me first with what you want built, your stack and your deadline. I'll confirm which package fits before you order.

FAQ
Can you work inside my existing codebase?
Yes. Send me access or a read-only copy and I'll tell you if the scope fits the package.
Do you build REST, JSON and GraphQL APIs?
Yes. REST and JSON APIs on Phoenix, and GraphQL with Absinthe or Ash GraphQL. Tell me which you need.
What does the $80 Basic package cover?
One small, defined task: a bug fix, a small change or a single endpoint, with a test. If your request is bigger, I'll say so and point you to Standard, Premium or a custom offer before you order. Contact me if you are in doubt, pls.
Do you use Ash, or plain Phoenix and Ecto?
Either. I'll recommend one after reading your requirements, and tell you why.
Do you use AI coding tools?
I do but when I do, I review every change before it reaches your repo. If you'd rather have none, say so in your first message. Without AI it would take longer.
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.
