What I'm looking for

I'm interested in Full-Stack Engineering, SaaS Development, Enterprise Applications, and Modern Web Technologies.

At Tech Crusades, I develop and maintain full-stack web applications, including SaaS platforms and business management systems. My work spans responsive interfaces, RESTful APIs, and authentication with role-based access control.

On Spotium, I developed a multi-tenant B2B sales intelligence platform for discovering target markets, companies, and decision-makers. I integrated OpenAI and third-party enrichment APIs to support business research workflows.

I also contributed to StaffOS, a workforce management and payroll platform, and developed RizMart, a full-stack e-commerce platform for customers in Pakistan. My independent projects include developer utilities on DevKitly and productivity tools on OutilSimple.
