Message

At Brainarcs, I engineered production backend logic across the full Rails MVC stack for platforms including Yulys and AruksWorld.

I standardized secure RESTful API endpoints and designed relational schemas, while refactoring PostgreSQL and MySQL queries and indexes to eliminate latency spikes.

I implemented background queues with Sidekiq and Redis, and integrated payment and messaging APIs using HTTParty. I also deployed authentication with Devise and OmniAuth.

I established automated testing with RSpec and Capybara using Test-Driven Development, and led a technical engineering team sprint initiative that cut production transaction and processing times by 30%.
