At CodeNote IT Solutions Private Limited, I upgraded applications from Ruby on Rails 6 to Rails 8 and Ruby 3.0.6 to Ruby 3.4.1, improving performance and maintainability.
I developed and maintained RESTful APIs and web applications using PostgreSQL, Hotwire, and Sidekiq. I also optimized SQL queries and background jobs, and monitored production issues with AppSignal and Sentry.
On Kreditz, a FinTech banking platform, I integrated Open Banking APIs and built secure account-connection workflows and RESTful APIs. I processed banking data and developed business logic for financial reports and certificates.
