Full-Stack Developer | SaaS & Automations Expert | AI Integrations
Islamabad, Pakistan - 8:23 am local time
I design and build scalable SaaS applications, full-stack web platforms, and secure API integrations using React, Node.js, and modern JavaScript/TypeScript ecosystems.
I help startups and growing businesses turn complex ideas into production-ready systems with clean architecture, strong database design, and long-term scalability.
---
I am a Full-Stack Web Developer with professional experience designing and delivering scalable web applications, SaaS platforms, and system integrations for startups and growing businesses.
I specialize in architecting end-to-end solutions including multi-tenant SaaS platforms, analytics dashboards, automation systems, and secure authentication infrastructures.
Recently, I transformed a single-client Meta Ads dashboard into a commercial multi-tenant SaaS platform now supporting 30+ agencies across:
• Meta Ads
• TikTok Ads
• Google Ads
This required restructuring the backend architecture, implementing tenant isolation, optimizing database performance, and building reliable high-volume data synchronization logic.
