Sobre este Serviço

As a Senior Backend Engineer with 5 years of industry experience, I help founders, CTOs, and engineering teams debug, modernize, and scale their server-side applications. Whether you need a quick emergency bug fix, a major gem dependency upgrade, or a complete microservice extraction, I write clean, well-tested, and maintainable code.

What I Can Do For You:

  • Ruby on Rails: Version upgrades (Rails 5/6 to 7+), gem dependency fixes, ActiveRecord query profiling, N+1 query elimination, and background job optimization (Sidekiq).
  • Golang (Go): Building high-concurrency microservices, gRPC/REST APIs, memory optimization, and channel-based thread management.
  • Database & Performance: Diagnosing database locks, query indexing, and schema migrations (PostgreSQL / MySQL).
  • Modernization & DevOps: Refactoring legacy codebases, writing unit/integration tests, and containerizing applications with Docker.

Why Choose Me?

  • Production-Grade Code: Clean, documented, and fully tested pull requests.
  • Architecture-First Mindset: Zero downtime migrations and safe database refactoring.
  • Fast Communication: Clear updates and progress tracking throughout the order.
