Agha Irfan Babar
Ruby craftsman. Building robust Rails applications for 9+ years
About
I am a Principal Software Engineer with over 9 years of experience in designing and delivering robust, scalable software solutions. My expertise lies in full-stack development, with a deep focus on the Ruby on Rails ecosystem and modern JavaScript frameworks including Angular, React, and Node.js.
Throughout my career, I have successfully delivered numerous projects as a top-rated freelancer on Upwork, helping clients transform complex ideas into production-ready applications. I specialize in building clean, maintainable code while staying at the forefront of emerging technologies.
My technical versatility spans across cloud platforms (AWS, Firebase, Heroku), containerization (Docker), and both SQL and NoSQL databases (PostgreSQL, MongoDB). I have experience working with massively scaled applications across various verticals including Finance, Healthcare, E-Commerce, and Social Networks.
I excel both as a solo high-impact developer and as a collaborative team member. Whether it's architecting new solutions from scratch, optimizing existing systems, or mentoring development teams, I bring a pragmatic approach focused on delivering real business value.
Currently based in Lahore, Pakistan, I'm available for remote opportunities including full-time positions, contract work, part-time engagements, and freelance projects.
