Job Success
Patiala, India - 3:23 am local time
I’m a Full Stack SaaS Developer focused on building scalable SaaS products, business platforms, AI-powered applications, and custom software from initial idea through production. I work with startups, founders, and established businesses to turn complex requirements into reliable, maintainable, and user-friendly products.
My core stack includes - React, Next.js, TypeScript, Python, FastAPI, Django, Node.js, PostgreSQL, MongoDB, AWS, Docker, and modern cloud technologies**. I work across the complete product lifecycle from architecture and MVP development to integrations, deployment, performance optimization, and ongoing improvements.
I’ve built and contributed to SaaS platforms, SAAS CRM and business management systems, customer portals, dashboards, subscription platforms, workflow automation tools, AI-powered applications, internal business systems, and data-driven products. I’m comfortable working on both new products and existing applications that need modernization, new features, performance improvements, or a more scalable architecture.
