Abhinav Raj

I’m a Ruby on Rails Developer with 5 years of overall software development experience, including 4.2+ years specialized in Ruby on Rails. I build production-grade, scalable web applications across fintech, digital publishing, and travel domains, with a strong focus on MVC architecture and RESTful APIs.

At Chetu India Pvt. Ltd., I built and scaled a multi-channel fundraising platform using Ruby on Rails and the Stripe API, supporting secure recurring subscription billing for thousands of monthly active donors. I also designed ActiveRecord models and associations for donor management, improving database query efficiency by 15% and reducing load times through better database design and reporting.

I bring disciplined engineering practices with test-driven development using RSpec, background jobs with Sidekiq, and structured Git workflows with code reviews. I’ve also integrated third-party services like Stripe and Sabre GDS/Travelport/Amadeus, and deployed applications on AWS and Heroku, while contributing to audit and compliance tooling using XML processing and Wicked PDF reporting.
