About this gig

Need help fixing or improving a Ruby on Rails API?


I will diagnose and resolve one API issue, improve an existing endpoint, or implement a focused API feature using Ruby on Rails, REST, GraphQL, PostgreSQL, Docker, and automated tests.

Depending on the package, you will receive a clear diagnosis, tested code, documentation, and integration guidance. I focus on maintainable solutions, reliable behavior, and clear communication throughout the work.


Please contact me before ordering so we can confirm the scope, access requirements, and the best package for your project.

I’m a senior backend and full-stack engineer with 10+ years of experience building reliable web products and APIs. I specialize in Ruby on Rails, GraphQL, PostgreSQL, AWS, Docker and performance-focused backend systems. I also build practical AI integrations using LLM APIs, RAG, structured outputs, tool-calling workflows and guardrails. I can help debug existing Rails applications, design clean APIs, integrate third-party services, improve reliability and introduce AI where it creates measurable value. I communicate clearly, work autonomously and collaborate comfortably with product
