Hi, I’m Ravi, Senior Backend Developer with 3+ years of experience building scalable, API-driven backend systems in the fintech domain. I specialize in Ruby on Rails, RESTful APIs, JWT authentication, MySQL/PostgreSQL, and performance optimization. Over the years, I’ve led multiple backend initiatives, mentored junior developers, reviewed code for best practices, and helped teams deliver high-quality, production-ready software. I’ve worked extensively on: 🔗 Third-party API integrations (ICICI Bank, TATA Capital, lending partners) 🚀 Performance optimization and reducing system load 🛠 Architecting API-first systems and migrating legacy codebases 🗄 Background job processing using Sidekiq 🧾 Excel/CSV processing (Roo, RubyXL, Axlsx) 🤝 Team leadership, mentoring, and code reviews I enjoy helping developers understand clean architecture, debugging, backend design patterns, ActiveRecord best practices, Git workflows, and how to think like a senior engineer.
