Sufyan I.

Full-Stack Development | REST APIs | PostgreSQL | MySQL | Redis | Elasticsearch | Rails 4–8 I’m a Principal Ruby on Rails Engineer and Full-Stack Developer with 10 years of professional experience, specializing in building scalable, production-ready web applications from scratch. I work across the complete development lifecycle from architecture, backend and frontend development to database management, deployment, optimization, and long-term maintenance. Throughout my career, I’ve worked with companies and projects including Co-Pilot (Elusa Health), Touring Plans USA, Italia Broad, GrapePedia, and Distro Payments, helping businesses turn ideas into fully functional, production-ready platforms. I’ve been responsible for building websites and applications from the ground up, taking them through development, deployment, ongoing maintenance, and scaling. My core expertise includes Ruby on Rails (Rails 4–8), React, JavaScript, REST APIs, PostgreSQL, MySQL, Redis, Elasticsearch, and modern full-stack development practices. I’m also experienced in working with legacy Rails applications, upgrading and modernizing older codebases, optimizing performance, fixing complex production issues, and designing systems that can scale. Beyond development, I focus on business impact. The platforms I’ve helped build and maintain have contributed to $400K+ in generated business through web-based products and platforms, giving me a strong understanding that successful development isn't just about writing code it’s about building reliable software that actually supports a business. If you need a developer who can own the entire technical process, work independently, understand business requirements, and take a product from an idea or legacy codebase all the way to production, I’m ready to help.
