The full picture

Hello, I’m Gunaseelan. I’m a Google IT Automation–certified Senior Full Stack Developer with 6+ years of experience building scalable SaaS platforms, enterprise integrations, and AI-powered systems. I currently work as a Product Lead & Senior Full Stack Developer at DCKAP Technologies, where I lead engineering initiatives, mentor developers, and architect reliable backend systems for global clients.

I started as a Laravel developer and grew into a product leader, managing cross-functional teams and delivering high-impact software across ERP, eCommerce, and SaaS ecosystems. I’m hands-on across the full development lifecycle — system design, backend APIs, frontend development, DevOps, CI/CD, testing, deployment, and performance optimization. My edge isn't just technical — it's the intersection of deep engineering, product intuition, and leadership. Currently pursuing an Executive MBA to close the loop between technology and business strategy.
