Muhammad Amir A.
Full-Stack Engineer | Architecting Scalable & Multi-Tenant SaaS
I help startups and businesses build production-ready SaaS platforms, AI-powered systems, and scalable web products that serve real users. With 5+ years of experience as a Full-Stack Engineer, I specialize in designing and deploying multi-tenant SaaS applications, automation platforms, and enterprise-grade systems using modern TypeScript-based architecture. I focus on building complete, business-ready platforms — not just features. Over the years, I have architected and developed systems including: • White-label EdTech SaaS platforms • AI-powered outreach and lead generation tools • Real-time communication and scheduling systems • Subscription-based platforms with complex workflows • Regulatory-compliant certificate generation platforms • High-performance CMS-driven comparison marketplaces Some of the platforms I’ve built include: 🔹 A fully white-label tutoring SaaS that connects students and teachers via live sessions, AI-powered homework support, and multi-role dashboards. 🔹 An AI-driven cold outreach and lead generation system that automates prospect discovery, multichannel campaigns, email personalization, and response management. 🔹 A regulated certificate generation platform used for property-based living space compliance workflows with automated approvals and digital signing. 🔹 A scalable mobile comparison platform optimized for performance, SEO, and structured data management. Across these systems, I’ve implemented: • Multi-portal architectures (Admin, User, Role-based systems) • AI integrations for automation and personalization • Real-time communication and notifications • Subscription and payment infrastructure • Document workflows and approval pipelines • White-label branding capabilities • Scalable cloud deployments Tech I use to build these systems: Languages: JavaScript, Typescript Frontend: Next.js, React, Tailwind CSS, MUI Backend: Node.js, Express, NestJS Database: MongoDB, PostgreSQL AI: OpenAI integrations Payments: Stripe Cloud: AWS & Azure Realtime: WebSockets I build systems that are designed to scale from MVP to real-world usage without needing re-architecture. If you're planning to build: • SaaS platform • AI product • Marketplace • Subscription system • White-label solution I can help turn your idea into a reliable, scalable product.
