Architecting scalable web systems, APIs, and cloud platforms across the full technology stack — from elegant frontends to robust backend infrastructure.
I'm Jai Wadhwa, a Full Stack Developer with over 15 years of hands-on experience building enterprise applications, scalable web systems, and cloud-hosted platforms for clients across industries worldwide.
My work spans the entire development lifecycle — from designing robust backend APIs and microservices to crafting responsive, performant frontends. Deep expertise in both PHP and JavaScript ecosystems, with proven cloud infrastructure experience on AWS and Azure.
I don't build templates. I build custom business solutions — workflow automation systems, payment integrations, enterprise dashboards, and high-traffic e-commerce platforms built to scale.
A comprehensive skill set built over 15 years of enterprise and commercial development.
