Ruby on Rails and React Product Development

I have contributed to an existing Ruby on Rails product across its marketing experience, dashboard workflows, frontend features, and API integrations. At RobinReach, this meant working with Rails, ERB, JavaScript, Tailwind CSS, and existing application behavior rather than replacing the product architecture.

  • Shipped more than five frontend features connected to Rails controllers and APIs.
  • Performance work reduced load time by approximately 45%.

Building inside an established Rails product

Contributing to an existing Rails product requires understanding how views, JavaScript behavior, controllers, and API responses fit together. At RobinReach I rebuilt parts of the marketing experience from Figma, redesigned dashboard workflows, and shipped frontend features within the existing application.

The work used Ruby on Rails, ERB, JavaScript, Tailwind CSS, and REST APIs. I connected frontend interactions to Rails controllers and existing product behavior, keeping the changes integrated rather than introducing a separate frontend application without a product need.

Measured product and performance outcomes

The RobinReach marketing work was associated with approximately 40% higher engagement and a 25% lower bounce rate. Dashboard changes were associated with approximately 30% higher daily active usage and 20% shorter onboarding time. These figures describe reported project outcomes, not a guarantee that the same changes produce the same results elsewhere.

Separate performance improvements reduced load time by approximately 45%. I treat performance work as part of product engineering: identify a real bottleneck, change the implementation, and measure the result in context.
