Building Scalable Backend Systems That Power Modern Applications
10+ years of crafting high-performance APIs, cloud infrastructure, and robust backend architectures using Laravel, Node.js, and AWS. Based in Lahore, Pakistan — working with clients worldwide.
Passionate Backend Engineer
With a Product Mindset
With over 10 years of hands-on experience in backend development, I specialize in building scalable, secure, and high-performance systems. My expertise spans from architecting RESTful APIs to deploying cloud-native applications on AWS.
I've led development teams, introduced CI/CD pipelines, migrated legacy systems to modern microservice architectures, and consistently delivered solutions that reduce costs and improve performance.
Whether you're a startup looking to build your MVP or an enterprise needing to modernize your backend — I bring both the technical depth and the leadership experience to get it done right.
